An allergy refers to a misguided reaction by our immune system in response to bodily contact with certain foreign substances. When these allergens come in contact with the body, it causes the immune system to develop an allergic reaction in people who are allergic to it. It is estimated that 50 million North Americans are affected by allergic conditions. The parts of the body that are prone to react to allergies include the eyes, nose, lungs, skin, and stomach. Common allergic disorders include hay fever, asthma, allergic eyes, allergic eczema, hives, and allergic shock.
Chronic urticaria is estimated to affect between 0·1–3% of children in the United Kingdom [1]. Physical factors, such as pressure and cold, are the most common identifiable trigger children with chronic urticaria usually also have angioedema. Approximately 30% of children with chronic urticaria have a positive ASST [39] and approximately 4% have positive thyroid peroxidase antibodies. It is suggested that thyroid function be monitored in children with chronic urticaria and positive thyroid autoantibodies, even though it has not been well established that treatment of clinical thyroid disease, if it develops, will improve the urticaria [65]. It has also been reported that children with severe chronic urticaria have a higher incidence of coeliac disease than controls [66].
Dermatographic urticaria (also known as dermatographism or “skin writing”) is marked by the appearance of weals or welts on the skin as a result of scratching or firm stroking of the skin. Seen in 4–5% of the population, it is one of the most common types of urticaria,[11] in which the skin becomes raised and inflamed when stroked, scratched, rubbed, and sometimes even slapped.[12]
For chronic hives, the doctor may suggest a non-sedating (non-drowsy) prescription or over-the-counter antihistamine to be taken every day. Not everyone responds to the same medications, though, so it’s important to work with a doctor to find the right one for your child.
Both urticaria and angioedema are a result of histamine and other chemicals released from mast cells in the skin and mucous membranes. This may occur through an allergic process or one in which mast cells release chemicals without IgE being involved.
Other measures may be appropriate, such as continuous ECG, blood pressure and pulse oximetry monitoring; administering intravenous crystalloids if the patient is hypotensive; and administering oxygen.
If non-sedating antihistamines are not effective, a 4 to 5-day course of oral prednisone (prednisolone) may be warranted in severe acute urticaria, particularly if there is angioedema. Systemic steroids do not speed up resolution of symptoms.
It occurs in both men and women, but appears to be more common in men than women. The condition tends to first appear in people aged between 10 and 30 years and persists for a number of years before it becomes less severe or goes away altogether. The natural course of cholinergic urticaria is quite variable, with most patients experiencing slow resolution over several years.
About 20% of people are affected.[2] Cases of short duration occur equally in males and females while cases of long duration are more common in females.[4] Cases of short duration are more common among children while cases of long duration are more common among those who are middle aged.[4] Hives have been described at least since the time of Hippocrates.[4] The term urticaria is from the Latin urtica meaning “nettle”.[5]

Antihistamines are also prescribed to treat chronic (lasting longer than 6 weeks) hives. When prescribed for chronic hives, you take this medicine every day to prevent hives from forming. There are many antihistamines on the market. Some make you drowsy, and some do not.
Certain foods or beverages, such as spoiled fish (scombroidosis), aged cheeses, or red wine, can contain histidine, which is closely related to histamine. These foods are often listed as causes of urticaria in the literature, but experimental evidence is scarce.
The rash appears rapidly, usually within a few minutes of sweating, and can last from 30 minutes to an hour or more before fading away. The mean duration is around 80 minutes. Typical signs and symptoms of the rash include:

My rash ravaged my body after the prednisone ended and I drank a glass of wine…. Big mistake. I thought it was poison ivy but nothing helps. I’m getting it yearly and it follows the nerve paths so if you have some helpful guidance I will check it out.
Individuals who have urticaria due to aspirin may need to avoid foods that contain high levels of salicylates. As well as this, antihistamines are the mainstay of drug treatment for urticaria and angioedema. They may be taken just when required or regularly to prevent episodes occurring in chronic spontaneous urticaria.
Urticaria. This is a close-up view of wheals with white-to-light-pink color centrally and peripheral erythema. These are the classic lesions of hives, or urticaria. Some hives are caused by allergies to such things as foods, medications, and insect stings, but the large majority of cases are not allergic, and no specific cause for them is ever found. It is characteristic that they are transient and highly pruritic. The goal of treating most cases of ordinary urticaria is to relieve symptoms while the condition goes away by itself.
Urticarial vasculitis tends to run a chronic course. Mortality is low, unless renal or pulmonary disease occurs. The goal of treatment is to achieve long-term control with the least amount of toxicity.
What we are referring to is allergens, or substances that cause the body to react in the form of an allergic reaction. This reaction can take many forms from fever, to swelling, stuffy nose, and depending on the severity of the allergy, possible even death. However, for this purpose of this article, we are going to focus on one of the most common reactions to allergens, and that is hives.

In addition to this, it would be wise to stick to a bland diet for a few days or until the symptoms subside. Avoid foods like shellfish, eggs, and pineapples as they could aggravate your condition. It would also be best if you also avoid milk and milk products, eggs, and soy products.
Hives, also known as urticaria, affects about 20 percent of people at some time during their lives. It can be triggered by many substances or situations and usually starts as an itchy patch of skin that turns into swollen red welts.
A much rarer type of urticaria, known as urticaria vasculitis, can cause blood vessels inside the skin to become inflamed. In these cases, the weals last longer than 24 hours, are more painful, and can leave a bruise.
This is variable. Most cases of idiopathic urticaria resolve over a period of six months but a minority can persist for many years. Some remit and then relapse. 50% of cases of chronic urticaria have resolved within 3-5 years. At least 20% of chronic urticaria patients requiring referral to secondary care are still symptomatic 10 years after first presentation. Factors associated with lasting duration include severe symptoms, associated angio-oedema and positive antithyroid antibodies.
Urticaria is due to activation of mast cells in the skin, resulting in the release of histamine and other mediators. These chemicals cause capillary leakage, which causes the swelling of the skin, and vasodilation causing the erythematous reaction. There may be a trigger identified which causes this release but often the cause is not identifiable, particularly in chronic urticaria. An autoimmune reaction is thought to be involved in many such cases.
Mast cells are the cells in the skin and mucous membranes that contain histamine. Release of histamine causes the allergic symptoms of hives and angioedema (swelling of large areas of the body). Itching is a common symptom when histamine is released. Anti-histamines are often prescribed to help control this symptom.
Urticaria is diagnosed in people with a history of weals that last less than 24 hours with or without angioedema. A family history should be elicited. A thorough physical examination should be undertaken.
Another possible explanation for your stress hives is that due to your weakened immune system, your skin is reacting to irritants that it never had problems with before: cold, heat, soaps, shampoos, lotions, laundry detergents, certain fabrics, sunlight, etc. In fact, there are even doctors that specialize in stress hives, known as psychodermatologists. These specialists work with skin illnesses and stress, and strongly feel that emotions that have not been properly dealt with can induce a rash in patients and that these deep seated emotions are the major cause of chronic hives.
Chronic hives (defined as lasting six weeks or more) can last from months to years. The evaluation of this condition is difficult, and allergy testing and other laboratory tests are only occasionally useful in such cases. The accurate evaluation of this condition requires the patient to give his or her physician precise information regarding their complete medical history, personal habits, and oral intake. Occasionally, it may be necessary to limit specific foods or drugs for a time to observe any affect upon the skin condition. Certain systemic diseases and infections, including parasitic infestations, may occasionally present in the skin as hives. If an inciting cause can be determined, then specific treatments for that condition ought to be effective, or in the case of food or drug allergy, strict avoidance would be necessary. There are additionally rare forms of chronic urticaria that are produced when the patient makes antibodies against molecules on the surface of their own mast cells. There are tests available to identify this type of hives.

They released their second studio album Veni Vidi Vicious in April 2000 through Burning Heart Records. The band themselves described the album as being like “a velvet glove with brass knuckles, both brutal and sophisticated at the same time”. The album yielded the singles “Hate to Say I Told You So”, “Main Offender”, “Die, All Right!”, and “Supply and Demand.”
Identification of causative allergens, from the clinical history and blood testing for specific IgE antibodies, will enable the individual with urticaria and angioedema to avoid pathogenic allergens. Where a reaction to medication has been implicated, for example, NSAID’s or antibiotics, the physician should identify alternative drug groups for future treatment, and if possible perform skin testing with antibiotics to confirm or refute the diagnosis of specific antibiotic allergy. Acute attacks of urticaria or angioedema can be treated with H1 antihistamines. Treatment with 1% menthol in aqueous cream may suppress itching. As wheals can occur where tight clothing is in contact with the skin, loose clothing should be recommended. Itching is worse in warm conditions, and a cool temperature, particularly in the bedroom, is recommended. If urticaria and angioedema have occurred during a systemic anaphylaxis reaction, the patient should be prescribed an auto-injector of epinephrine to carry. Very often an episode of urticaria occurs without any explanation or lasting clinical significance, and without any risk of recurrence. Patients unresponsive to antihistamines can be treated with a tapering course of corticosteroid.  
Usually no tests are needed. The rash is very typical and is easily recognised as hives by doctors. In many cases you will know what caused the rash from the events leading up to it. (For example if you have just been put on a new medicine, or if your skin came into contact with a nettle, or if you were stung by a bee.) In some cases it may be helpful to have some allergy tests such as skin prick tests to help determine the specific cause. Sometimes blood tests for allergies can be helpful. Occasionally, if urticarial vasculitis is suspected, a sample of the skin may be taken (a skin biopsy) for further analysis.
If you are constantly worried about what causes hives then you should understand that when you expose your body to excessive stress either for a small amount of time or perhaps a long period of time your own body’s immune system sets out to falter and it starts sending histamine for the body to handle what is causing problem.
Mast cells are like land-mines, and contain bags filled with chemicals including histamine. When these are released into the skin in small amounts, they cause itching and irritation. When large amounts are released into the skin, fluid leaks out of blood vessels, resulting in swelling of the skin (hives). 
Loratadine (Claritin, 10 milligrams) and fexofenadine (Allegra) are antihistamines available over the counter that are less likely to cause drowsiness. Also approved for over-the-counter use is hydroxyzine (Atarax, Vistaril), which causes drowsiness, and its breakdown product, cetirizine (Zyrtec, 10 milligrams), which is less sedating.
To diagnose chronic hives the doctor will first make sure that the hives are not caused by infection or an underlying disease state. However, in the evaluation of patients with chronic urticaria, it is their history which is the most important diagnosis tool. The physician will look for clues regarding drug or chemical exposure, changes in dietary habits, changes in personal habits, alterations in residence or place of employment. She/he will also look for a pattern such as: Is there a relationship to eating? Does the patient wake-up with hives? Are they as likely to occur at home as at work/school? Are weekends or weekdays different in any way? The physician will often place a patient with chronic urticaria on a diet to see if elimination of the hive-trigger will bring relief. It is important to see a doctor before going on an elimination diet. Systemic diseases should be ruled out with this appointment. Sometimes these diseases can cause hives that are painful or burning in nature.
In acute (short-lived) hives, the weals may come and go for a few days or weeks. Rarely, they persist for more than six weeks. Chronic hives is much less common. The weals come and go for months or even years. 
The skin is the body’s largest organ, so it’s not uncommon for a variety of other medical conditions to affect it and this may result hives. For instance, people with cancers like lymphoma may be prone to hives, as are those dealing with carcinomas (skin cancer).​

The medical term for hives is urticaria (ur-tih-CARE-ee-uh). When large welts occur deeper under the skin, the medical term is angioedema (an-gee-oh-eh-dee-ma). This can occur with hives, and often causes the eyelids and lips to swell.
Hives are patches of puffy, red, itchy or inflamed skin also known as urticaria, and they can be caused or worsened by significant stress in your life. In fact, stress is one of the most common causes of acute hives (hives that last less than six weeks), along with infectious causes and allergies. Stress has also been known to worsen chronic hives (hives that last more than six weeks), even when the chronic hives are primarily due to another cause.
Chronic or recurrent urticaria (>6 wk) – Basic laboratory studies should include complete blood count (CBC), erythrocyte sedimentation rate (ESR), thyroid-stimulating hormone (TSH), and antinuclear antibody (ANA) [4]
Diagnosis is by skin biopsy, taken ideally from a ‘new’ lesion (within 12 h of appearance), which shows a small vessel leucocytoclastic vasculitis involving post-capillary venules, with endothelial cell swelling, a neutrophil cell infiltrate, extravasation of red blood cells and fibrinoid deposits in and around blood vessels [75]. The condition is thought to be mediated via a type III/immune complex hypersensitivity reaction, in which antigen/antibody complexes deposit in vessel walls. This results in complement activation, neutrophil chemotaxis and infiltration and the release of proteolytic neutrophil enzymes, such as collagenases and elastases, which cause tissue damage. Immunofluorescence shows deposition of immunoglobulin and complement.

In rare cases, hives or angioedema can be early symptoms of anaphylaxis. Anaphylaxis requires immediate medical attention. If you suspect you are having  an anaphylactic reaction, seek urgent medical treatment. Without proper treatment, anaphylaxis can be deadly.
In general, if an allergic reaction causes hives or swelling, it is usually ingested (food, oral drug) or injected (drugs, stings). If an allergen can penetrate the skin locally, hives will develop at the site of exposure. For example, contact urticaria may occur following exposure to latex gloves if sufficient latex penetrates through the skin.

So, what’s changed? While genes don’t change that fast, probably our environment has. Marshall believes more air pollution, along with a “squeaky clean society,” each play a role in increasing allergies.
Chronic hives may be treated with antihistamines or a combination of medications. When antihistamines don’t provide relief, oral corticosteroids may be prescribed. A biologic drug, omalizumab (Xolair), is also approved to treat chronic hives in those at least 12 years of age.
Hives are red and sometimes itchy bumps on your skin. An allergic reaction to a drug or food usually causes them. Allergic reactions cause your body to release chemicals that can make your skin swell up in hives. People who have other allergies are more likely to get hives than other people. Other causes include infections and stress.

The main symptom of urticaria is a red, raised skin rash. They can appear anywhere on the body, including the face, hands, lips, tongue, throat or ears. Hives vary in size (from a pencil rubber to a dinner plate), and may join together to form larger areas known as plaques.
Although systemic treatment is best avoided during pregnancy and breast feeding, there have been no reports that second-generation antihistamines cause birth defects. If treatment is required, loratidine and cetirizine are currently preferred.

Hives can further be categorized by how long they last. Acute hives last for less than six weeks; chronic hives can last longer. In many cases, a trigger causes acute hives is not the same as what causes chronic hives.

In the overwhelming majority of cases it is not “something” causing the chronic hives, it is “nothing.” That is, in about 95% of chronic hives cases, the hives are “idiopathic” (a medical term that means there is no discernible cause). Because of those 5% of cases with a cause, it is worthwhile to see a physician to determine if any underlying disease is present (e.g. thyroid problems, liver problems, skin diseases, sinusitis) or if there is an allergic cause (i.e. a reaction to a drug, insect, food, etc.). This can be accomplished by a good history and physical, a few blood and urine tests and sometimes a skin biopsy. Some patients with chronic hives and elevated anti-thyroid antibodies in the blood improve when given thyroid supplement even if the thyroid function is normal.
Psoriasis is a buildup of too many skin cells that form silvery, scaly patches on the body. It’s caused by inflammation, which can be fueled by stress. That’s why people with psoriasis often get flare-ups when they’re tense.

Research shows that stress can play a major role in many physical and mental illnesses, including chronic idiopathic hives. “Stress can bring on and exacerbate chronic hives,” says Anand. “It’s not uncommon to see chronic idiopathic hives developing following a stressful period of time.” In several studies, people with chronic hives have been found to have higher levels of stress. Researchers have also found a link between post-traumatic stress disorder and hives. To lower stress, try relaxation techniques — for example, mindfulness meditation, which was found to lower the stress hormone cortisol in a study published in 2013 in the journal Health Psychology.
Stress hives are also known as a stress rash or as stress bumps. They develop due to chronic stress or tension, and appear as red raised areas and swollen areas on the skin that seem to suddenly appear. They cause itching most of the time, and some people report having a burning or stinging sensation wherever they appear. Learn more about how stress can cause chronic urticaria on our stress rash page.
A hive often goes away in 24 hours or less. New hives may appear as old ones fade, so hives may last for a few days or longer. A bout of hives usually lasts less than 6 weeks. These hives are called acute hives. If hives last more than 6 weeks, they are called chronic hives.

In this study 5 persons reported with lice and fleas (same species of parasites had been collected from the pigeons nest) and all of them had itching in their head and allergic urticarial reaction, Haag wackermagel (2004) has reported concerns a married couple who were repeatedly invaded by pigeon fleas (Ceratophyllus columbae) over a period of 2 months.
Curing a stress rash is actually pretty simple and doesn’t require any type of medical procedure. In fact, it’s as simple as reducing the amount of stress in your life. As you become less stressed, the hives will naturally go away. Read my post — 170 Stress Management Techniques — to help lower the amount of stress in your life.
Hives can also develop as a result of sun or cold exposure, infections, excessive perspiration, and emotional stress. The reason why stress seems to precipitate an outbreak of hives in many people is not completely understood but is likely related to the known effects of stress on the immune system. In many cases, the cause of hives in a given individual cannot be identified.
I went in some hay and got the hives on the back of my legs so close together it looked like one big red/pink spot on the back of my legs so i took 2 cold rags and put them on the back of my legs for about 8-10 minutes and TOTALLY relieved itching.
Check CH50, C3, C4, Clq, and antibodies to Clq in urticarial vasculitis patients. If these test results are positive, evaluate renal function and urinalysis to check for the effects of vasculitis on the kidneys.
When you have an allergic reaction to a substance, your body releases histamine and other chemicals into the blood. This causes itching, swelling, and other symptoms. Hives are a common reaction. People with other allergies, such as hay fever, often get hives.
Urticaria and angioedema are commonly classified by duration. Lesions of less than six weeks’ duration are considered acute; episodes that persist beyond six weeks are designated chronic. The causes mechanisms of hive formation are different in each instance, as are the prognosis and approaches to treatment.
Chronic spontaneous urticaria is mainly idiopathic (cause unknown). An autoimmune cause is likely. About half of investigated patients carry functional IgG autoantibodies to immunoglobulin IgE or high-affinity receptor FcεRIα.
In a small percentage of patients with chronic urticaria, perhaps about 2% [71], there is an underlying small vessel vasculitis. It is important to diagnose these patients because they may have an associated systemic illness which can lead to severe complications and because the treatment of urticarial vasculitis differs from that of ordinary chronic urticaria. Clinically, the lesions of urticarial vasculitis are longer-lasting (3–7 days) than those of ordinary chronic urticaria. They are often painful or ‘burning’ and they may leave residual bruising or hyperpigmentation of the skin. Approximately 40% of patients with urticarial vasculitis will have associated angioedema. Urticarial vasculitis may occur at any age, but the median age of incidence is 43 years. Women are affected twice as often as men. Two categories of urticarial vasculitis are recognized – hypocomplementaemic and normocomplementaemic [72]. Patients with hypocomplementaemic urticarial vasculitis syndrome (HUVS) are more likely to have an associated connective tissue disease and systemic symptoms than patients with normal complement levels [73] and may have IgG antibodies to the collagen-like domain of C1q [74]. There may be associated fever, arthralgia (50%), gastrointestinal involvement with abdominal pain, nausea, vomiting and diarrhoea (20%); pulmonary disease with dyspnoea or pulmonary effusions (20%); and glomerulonephritis with haematuria and proteinuria (5–10%). Progressive renal disease is rare, unless the urticarial vasculitis is associated with SLE. Other rare manifestations include eye involvement, lymphadenopathy, splenomegaly and pericardial effusions.
Complement-mediated urticaria includes viral and bacterial infections, serum sickness, and transfusion reactions. Urticarial transfusion reactions occur when allergenic substances in the plasma of the donated blood product react with preexisting IgE antibodies in the recipient. Certain drugs (opioids, vecuronium, succinylcholine, vancomycin, and others) as well as radiocontrast agents cause urticaria due to mast cell degranulation through a non-IgE-mediated mechanism. Urticaria from nonsteroidal anti-inflammatory drugs (NSAIDs) may be IgE-mediated or due to mast cell degranulation, and there may be significant cross-reactivity among the NSAIDs in causing urticaria and anaphylaxis. [6]
Get away from the allergens. The first step in treating hives is to ensure you are away from the source of the allergic response. If you know what it is, which is how most cases of hives are, remove the substance that is causing the allergic reaction from your skin or environment. Common allergens that are easy to determine are poison ivy, poison oak, insect bites, wool clothing, a cat, or a dog. Avoid these or any other known allergen as much as possible.

Acute urticaria is diagnosed in people with a short history of weals that last less than 24 hours, with or without angioedema. A thorough physical examination should be undertaken to look for underlying causes.
These red areas will usually appear small, but can easily multiply and singular welts join together forming rashes. The area affected will be slightly elevated with a blanched center, especially when you press down your finger on the area of the rash. It is estimated that 20% of people will experience urticaria at some point in their lives. While it is common for the appearance of welts to form on the skin during an allergic reaction, it is also important to note that they can occur internally, which is why it is so important to speak to a doctor immediately, especially if you are unaware as to the cause of the reaction.
Exercise daily. Even if you only have time to take a walk, exercise helps reduce stress hormones that may cause you to feel keyed up. And remember, exercise produces epinephrine, which acts as a natural decongestant, helping you breathe better.
Food allergy should be considered in acute urticaria and urticaria in children. Such foods as tree nuts, peanuts, eggs, shellfish, and tomatoes should be considered (the involvement of food additives or preservatives is controversial). [10] ) Please visit our main article to learn more about food allergies.
No. Seriously, stress is a mental state. And we treat mental problems with mind treatment, not with supplements. This advice, unfortunately, fails to find and explain the real cause of your stress problem.
Antihistamines are the first line medication for acute or chronic urticaria. Some of these are over-the-counter preparations. The newer anti-histamines are less sedating and therefore can be used in the daytime as well. Most of them are long-acting and can be taken once-a-day only. Normal prescribed dosages may not be of benefit and your doctor may often prescribe larger doses or the addition of a second medication. Sometimes a specific anti-ulcer treatment which also has some effect on blocking urticaria may be used. If no relief is obtained a doctor should be consulted.
The most common stressful events that were related to the occurrence of hives included the death of a family member, family conflicts, financial problems, sexual dysfunction, illness of a family member, problems in the workplace, and extramarital affairs. Even forms of good stress—such as getting married or engaged, and going on a vacation—can cause hives. The authors propose that the treatment of stress through relaxation techniques and stress management programs may be useful for the treatment of hives caused or worsened by stress.
The best treatment for hives and angiodema is to identify and remove the trigger, but this is not an easy task. Antihistamines are usually prescribed by your doctor to provide relief from symptoms. Antihistamines work best if taken on a regular schedule to prevent hives from forming in the first place.
Oral glucocorticoids are effective in controlling symptoms of chronic hives however they have an extensive list of adverse effects such as adrenal suppression, weight gain, osteoporosis, hyperglycemia, etc. Therefore, their use should be limited to a couple of weeks. In addition, one study found that systemic glucocorticoids combined with antihistamines did not hasten the time to symptom control compared with antihistamines alone.[41]
Acute urticaria may be, in a short time, associated with life-threatening angioedema and/or anaphylactic shock, although it usually presents as rapid-onset shock without urticaria or angioedema. (See Emergency Care and Complications.)
It occurs in both men and women, but appears to be more common in men than women. The condition tends to first appear in people aged between 10 and 30 years and persists for a number of years before it becomes less severe or goes away altogether. The natural course of cholinergic urticaria is quite variable, with most patients experiencing slow resolution over several years.
The Hives have released five studio albums: Barely Legal (1997), Veni Vidi Vicious (2000), Tyrannosaurus Hives (2004), The Black and White Album (2007) and Lex Hives (2012). They have one compilation album, Your New Favourite Band (2001) and they have issued a live DVD, Tussles in Brussels (2005).[3] The Black and White Album has been their most successful as of December 2017.
Clinical Context:  Although prednisone is most effective, adverse effect profiles preclude it from use as a first-line agent. Consider it only after failure of antihistamines, indomethacin, colchicine, dapsone, or hydroxychloroquine. Its effect on urticarial vasculitis likely is mediated by its anti-inflammatory effect. This class of medications decreases capillary permeability and inhibits the mitotic rate of lymphocytes.

Stress hives are red, raised swollen areas and bumps (AKA stress bumps) that appear on your skin, that develop due to too much stress or anxiety in your life. Stress hives can itch like crazy, giving you the feeling like ants or spiders are crawling over your skin. The only way to get rid of your stress hives is to remove all the stress and anxiety form your life. Because this is a near impossibility for most people, there is one stress hives treatment, known as OxyHives, that can be taken that reduces the swelling and itchy feeling within 2 hours.
Early lesions show a perivascular neutrophilic infiltrate involving postcapillary venules. Leukocytoclasis is present, expansion of the vessel wall occurs, and the endothelium is intact. Eosinophils may be noted early. Fibrin deposition and extravasation of red blood cells ensue.
Fortunately, it’s easy to find out whether cold is one of your triggers: Your doctor can administer a simple test that involves placing an ice cube on your skin for five minutes to see if a reaction occurs. If it turns out that cold is a trigger for you, your doctor will recommend that you protect your skin from the cold and take your medications as prescribed.
Hives usually cause itching, but may also burn or sting. They can appear anywhere on the body, including the face, lips, tongue, throat, or ears. Hives vary in size (from a pencil eraser to a dinner plate), and may join together to form larger areas known as plaques. They can last for hours, or up to one day before fading. Read more about hives (urticaria and angioedema).
Angioedema is another skin allergy and is the name given to deeper swelling affecting the skin over the arms, legs, torso or face. It may also affect the tongue, mouth, throat and sometimes the upper airway. These swellings commonly last for more than 24hrs, and usually there is no itching. It is not possible to identify an underlying cause for angioedema in the vast majority of cases.
Your doctor will need to ask many questions in an attempt to find the possible cause of hives or angiodema. Since there are no specific tests for hives — or the associated swelling of angioedema — testing will depend on your medical history and a thorough exam by your primary care doctor or dermatologist.
Most chronic urticaria is idiopathic. The next most common cause is an autoimmune disorder. The causative autoimmune disease is sometimes clinically apparent. Urticarial vasculitis sometimes is associated with connective tissue disorders (particularly SLE or Sjögren syndrome). In urticarial vasculitis, urticaria is accompanied by findings of cutaneous vasculitis; it should be considered when the urticaria is painful rather than pruritic, lasts > 48 h, does not blanch, or is accompanied by vesicles or purpura.
The most common food allergies are to eggs, nuts, milk, peanuts, fish, shellfish, strawberries and tomatoes. Symptoms and signs include nausea, vomiting, diarrhea, abdominal pain, itching, hives, eczema, asthma, lightheadedness, and anaphylaxis. Allergy skin tests, RAST, and ELISA tests may be used to diagnose a food allergy. Though dietary avoidance may be sufficient treatment for mild allergies, the use of an Epipen may be necessary for severe food allergies.
Question on Papular Urticaria: Is Urticaria & Papuller Urticaria the same? My 15 yr old sis is suffering from Papullar Urticaria since 2 yrs. We tried all medication including Allopathic (also Steroids), homeopathy. But no improvement. Pls suggest a remed
Idiopathic cold urticaria is characterized by the rapid onset of pruritus, erythema, and swelling after exposure to a cold stimulus. The location of the swelling is confined to those parts of the body that have been exposed. When suspected, an ice-cube test can be performed in which an ice cube is placed on the subject’s forearm for 4-5 minutes. A positive reaction leads to formation of a hive in the shape of the ice cube within 10 minutes after the stimulus is removed (click for picture). The time course of this reaction (i.e., cold challenge followed by hive formation as the area returns to body temperature) demonstrates that a two-step reaction has occurred in which exposure to cold is a prerequisite, but hive formation actually occurs as the temperature increases.
Information regarding history of previous urticaria and duration of rash and itching is useful for categorizing urticaria as acute, recurrent, or chronic. For chronic or recurrent urticaria, important considerations include previous causative factors and the effectiveness of various treatments, as follows [2] :
Acute viral illnesses in children can be associated with urticarial eruptions which last a few weeks and then spontaneously subside. This typically accompanies symptoms of viral rhinitis, pharyngitis, or bronchitis. When such patients are given an antibiotic, the cause of the hives becomes less clear because a drug reaction becomes an alternative possibility. If penicillin or related antibiotics have been given it is worth performing skin testing for penicillin and/or cephalosporin allergy, rather than making unsubstantiated assumption that the child is “penicillin allergic.” Hepatitis B, infectious mononucleosis (EB virus) and a large number of helminthic parasites may be associated with hives in all age groups.
Get away from the allergens. The first step in treating hives is to ensure you are away from the source of the allergic response. If you know what it is, which is how most cases of hives are, remove the substance that is causing the allergic reaction from your skin or environment. Common allergens that are easy to determine are poison ivy, poison oak, insect bites, wool clothing, a cat, or a dog. Avoid these or any other known allergen as much as possible.

“que es la urticaria _what is urticaria”

While there are several different types of hives that can appear as a result of a reaction, most of their signs and symptoms are similar. Bearing that in mind, we have taken the time to put together 10 of the most common signs of hives, so you can be prepared in the event they occur, and can reach out to a medical professional to get to the bottom of it.
How do you get hives? Hives are not something you can “catch” from anyone. Rather, they are your body’s response to something it ingests or experiences. The cause of hives can be a certain food, drug, infection or stress. You might be surprised to learn that stress is one of the most common causes of acute hives, along with allergies and infectious causes. Hives can literally occur at any age and appear anywhere on the body. It is estimated that one in every five people will be affected by a hives outbreak at some point in his or her life. (2)
Acute hives can be related to other infections such as strep throat, athlete’s foot, mononucleosis, and coxsackie viruses. Though they’re not viral infections, both intestinal worms and malaria can also cause urticaria.
Professional Reference articles are written by UK doctors and are based on research evidence, UK and European Guidelines. They are designed for health professionals to use. You may find the Hives (Chronic Urticaria) article more useful, or one of our other health articles.
When we’re exposed to a stressful situation, our bodies prepare for confrontation. This “fight or flight” response is controlled by our hormones and nervous system and dates back to prehistory, as we prepared to fight or flee our stressor.
There are no routine diagnostic tests in chronic spontaneous urticaria apart from blood count and C-reactive protein (CBC, CRP), but investigations may be undertaken if an underlying disorder is suspected.
Antihistamines are also prescribed to treat chronic (lasting longer than 6 weeks) hives. When prescribed for chronic hives, you take this medicine every day to prevent hives from forming. There are many antihistamines on the market. Some make you drowsy, and some do not.

Codeine and other opiate-derived medications can cause degranulation of mast cells by stimulation of opiate receptors. Urticaria and angioedema can result from agents that alter the metabolism of arachidonic acid, such as aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs). These responses to NSAIDs have the potential to be fulminant with generalized hives swelling. Angiotensin-converting enzyme inhibitors (ACEIs), drugs used to treat hypertension, (eg, Captopril) can cause recurrent episodes of angioedema, but urticarial skin lesions are not observed. Because ACE normally inactivates bradykinin, the angioedema is thought to be due to elevated bradykinin levels causing dilation and leaking of vessels in deep layers of the skin. This is the most common cause of angioedema seen in emergency rooms. Tongue, throat and laryngeal swelling can be extremely severe and intubation may be necessary. The swelling resembles that seen in hereditary or acquired C1 inhibitor deficiency where bradykinin is also the mediator of swelling.
The most common food allergies in adults are shellfish and nuts. The most common food allergies in children are shellfish, nuts, eggs, wheat, and soy. One study showed Balsam of Peru, which is in many processed foods, to be the most common cause of immediate contact urticaria.[8] A less common cause is exposure to certain bacteria, such as Streptococcus species or possibly Helicobacter pylori.[9]
In patients with chronic idiopathic urticaria, approximately 35% will experience episodes of angioedema and 25% are positive for dermatographism. Like many autoimmune diseases, chronic idiopathic urticaria has a higher incidence in women than men, with the reported ratio of females to males ranging from 2:1 to 4:1. Numerous autoimmune conditions have been associated with chronic idiopathic urticaria, including thyroid disease, celiac disease, and rheumatoid arthritis (RA).
Yang, H. Y., Sun, C. C., Wu, Y. C, & Wang, J. D. (2005, April). Stress, insomnia, and chronic idiopathic urticaria, a case-control study. Journal of the Formosan Medical Association,104(4):254-63. Retrieved from https://www.ncbi.nlm.nih.gov/pubmed/15909063
Drugs that block histamine-1 (H1) receptors (antihistamines) are the primary treatment for urticaria. The use of both H1 and H2 receptor blockers has been recommended but has not been proven more effective. Patients should avoid identified allergens. Doxepin, calcium channel blockers, or immunosuppresive drugs may be needed for symptoms that are not well controlled with antihistamines. Known triggers of urticaria should be avoided.
They also play a central role in allergy. Mast cells contain sacks filled with chemicals, including histamine. These chemicals are released in response to certain external triggers, e.g., allergens, physical causes. Some individuals’ mast cells are unstable and cause urticaria without being triggered by an external factor. When these chemicals are released in small amounts, they cause local itch, irritation and redness of the overlying skin. In larger amounts, they will cause fluid to leak out of blood vessels, resulting in swelling of the skin. When released in massive amounts, it may result in shock (anaphylaxis).
Have you ever had red, raised, itchy bumps that came out of nowhere? If the answer is “yes,” then you likely have already experienced hives at some point in your life. Hives can really startle you when they suddenly appear on your skin. Most often they are due to some type of allergic reaction. Thankfully, they’re typically not long lasting and relatively harmless. But, sometimes hives can indicate a life-threatening allergic reaction, or they can become chronic. (1)
Urticaria results from the release of histamine, bradykinin, leukotriene C4, prostaglandin D2, and other vasoactive substances from mast cells and basophils in the dermis. [2] These substances cause extravasation of plasma into the dermis, leading to the urticarial lesion. The intense pruritus of urticaria is a result of histamine released into the dermis. One study showed that D-dimer levels correlate with the severity of acute urticaria and may serve as a marker of disease severity. [75]  
Studies have shown that a substantial number of patients with chronic urticaria have a positive autologous skin test, meaning that injection of the patient’s serum in a skin test leads to a significant wheal and flare reaction. A proportion of such patients (about 35%) have been found to have an IgG antibody directed against the alpha- subunit of the IgE receptor which experimentally can cause degranulation of histamine-containing cells (blood basophils or mast cells). A smaller proportion have anti-IgE antibodies (5%). This accounts for 40% of patients with CSU. Fifty percent of patients with CSU have circulating basophils that are hyporesponsive to activation by anti IgE due to high intracellular phosphatase levels and this reverts to normal during therapy or remission.  Mechanisms for histamine release caused by the aforementioned autoantibodies have been described but proof of their pathogenicity is lacking.  Yet virtually all diseases strongly associated with autoimmunity turn out to be autoimmune.
If you suffer with allergy symptoms, you know all about the stress of having a chronic condition. Not only is it difficult to breathe with allergy symptoms, but poor sleep can lead to fatigue and problems concentrating. Allergy medicines can cause appetite changes, low energy, and even irritability. All you want is relief: from the stress, the symptoms, all of it.
Idiopathic cold urticaria is characterized by the rapid onset of pruritus, erythema, and swelling after exposure to a cold stimulus. The location of the swelling is confined to those parts of the body that have been exposed. When suspected, an ice-cube test can be performed in which an ice cube is placed on the subject’s forearm for 4-5 minutes. A positive reaction leads to formation of a hive in the shape of the ice cube within 10 minutes after the stimulus is removed (click for picture). The time course of this reaction (i.e., cold challenge followed by hive formation as the area returns to body temperature) demonstrates that a two-step reaction has occurred in which exposure to cold is a prerequisite, but hive formation actually occurs as the temperature increases.
When a patient has hives, a dermatologist can often make the diagnosis by looking at the skin. Finding the cause of hives, however, can be a challenge. This is especially true for hives that have been around for more than 6 weeks.
In 50% of patients with acute urticaria, a specific etiology can be identified. Brief episodes of urticaria can be associated with identifiable causes, and the method of exposure (ie, direct contact, oral or intravenous routes) is usually known. Urticaria is often associated with a recent infection.
Psychological stress exacerbates chronic urticaria through a variety of mechanisms, including heightened basophil response to corticotrophin releasing factor and adrenocorticotropic hormone (ACTH) and a derangement of the hypothalamic-pituitary-adrenal (HPA) axis (Dyke SM, Carey BS, Kaminski ER. Clin Exp Allergy. 2008;38(1):86-92).
I viewers, I was diagnosed officially in March 2015. I’ve SO MANY symptoms! The “diabetic nerve pain”-tho I’m NOT Diabetic! Just LOTS of it! The tingling, & numbness & fatigue and ALL the rest! Do I HAVE to live the remainder of my life this way? I don’t even have the energy to get my NORMAL tests, let alone an M.S. one! To get out of bed& go out is BEYOND a chore for me! Nobody would understand it! My life was a living nightmare – in ADDITION to what I have to endure with one of my sons.(I can’t even take care of him) – I desperately search for an alternative cure to save my life till a friend of mine from UK told me about Dr. MOHAMEND from AFRICA who cured her husband from ALS, PLS, and FSHD with His Herbal Healing OIL, ROOT and HERBS. I contacted Dr. MOHAMEND through His what’sapp number and told him about my MS problem and he assured me that I will be CURED that he has CURES to any disease and VIRUS. I was very happy to hear that from him. I place an ORDER and he sent it through a courier delivery service to my address which I sent to him. I received it within 4 days and immediately commerce usage as prescribed by Dr. MOHAMEND In the first one week of usage, I started noticing great change all over my body, I was now gaining STRENGHT gradually, after three weeks, I was able to move my arms and legs, talk and also swallow. I was totally CUREDof MS disease after six weeks. You can contact Dr. MOHAMEND via his email: drmohamendherbalremedy@gmail.com or call/whatsapp on +2348148010628. My FAMILY and I refer people to HIM everyday and everyone who has contacted him is recovering and seeing REVERSAL in SYMPTOMS. Please share this with anyone you know is suffering from ALS, PLS, MS, MSA, FSHD, Parkinson’s, and Fibromyalgia. I believe he treats more than those things, so if you have questions please just call. Can’t hurt. Let me know if you have any questions! I’ll be Happy to help through my email: zandrasmithon@gmail.com. I don’t want anyone else to die with this hideous disease! God bless.
Acute urticaria may be, in a short time, associated with life-threatening angioedema and/or anaphylactic shock, although it usually presents as rapid-onset shock without urticaria or angioedema. (See Emergency Care and Complications.)

“urticaria dermatographism |baby hives treatment”

To check for physical hives, a doctor may put ice on your child’s skin to see how it reacts to cold or place a sandbag or other heavy object on the thighs to see if the pressure will cause hives to appear.
Many different drugs may cause urticaria. The cyclo-oxygenase (COX)-inhibitor drugs such as aspirin [22] and NSAIDs [23] are a common cause. Opiates, including codeine, may trigger direct histamine release from mast cells [24]. Many different over-the-counter analgesics contain aspirin, NSAIDs and/or codeine and it is therefore important to be specific as to exactly which painkillers patients may or may not be able to take. These reactions are not IgE-mediated and specific IgE testing for aspirin, NSAIDs and opiates is not indicated. Evidence of oxidative damage, as shown by increased protein carbonylation and lipid peroxidation, and of increased anti-oxidant enzyme activity has been found in patients who develop non-IgE-mediated drug-related urticaria [25]; however, it is not known if this oxidative stress is the cause or the effect of the reaction. [Drugs such as angiotensin converting enzyme inhibitors (ACEI) and statins cause isolated angioedema much more commonly than urticaria]. Radio-contrast media and plasma substitutes may also cause urticarial reactions.
The immune system normally protects us by making antibodies against foreign invaders such as bacteria and viruses. These antibodies are called IgG and are often referred to as gammaglobulins. Usually, IgG is not formed to any normal body tissue but occasionally, by error, this does happen. If antibody binds to normal tissues it can cause damage to the body or create other disease symptoms. Rheumatoid arthritis is a good example of an autoimmune disease. Antibodies that react with body tissues are felt to contribute to joint swelling and pain. Many other common diseases are caused by autoimmunity such as juvenile diabetes and low thyroid disease.
Chronic hives can be a telltale sign of a larger problem, and extensive blood work may be necessary to pinpoint the underlying issue. Dr. Jaliman says patients with lupus, lymphoma, thyroid disease, hepatitis, or HIV may have hives as a symptom of their illness. Since these people tend to suffer from chronic hives, medications are the most reliable form of relief.
Take quercetin. Quercetin can also be effective in reducing inflammation and swelling. It is a flavonoid produced in the body from rutin.[18][19] Eat more fruits and vegetables, such as apples, citrus fruits, onions, sage, parsley, dark cherries, grapes, blueberries, blackberries, and bilberries, to get more quercetin in your diet. You can also drink more tea and red wine or use more olive oil to increase your intake of it. You can take quercetin as a dietary supplement as well.[20]
The #1 best proven method of eliminating stress hives from your life forever is to remove ALL stress and tension from your life. Aside from that, the only other way is to take an OTC medication like OxyHives that has proven to get rid of hives within 1-2 hours. OxyHives has been around for over 10 years now and is effective without any of the harmful side effects other hives medications have. OxyHives recently received approval to sell their hives treatment over the counter and thus no longer requires a prescription. Please see our hives treatment page for more information.
Winter is not exactly the most popular season, and with good reason for those who live with chronic hives: The cold can trigger a flare-up in some. Besides the weather, other cold-related triggers include chilly foods and swimming pools. For people who are allergic to the cold, full-body immersion in a swimming pool, in particular, can trigger a severe reaction that involves not just hives but allergic shock (anaphylaxis) and loss of consciousness.

Urticaria has been reported with infectious diseases. Viral infections associated with acute urticaria include acute viral syndromes, hepatitis (A, B, and C), Epstein-Barr virus, and herpes simplex virus. Streptococcal infection (see the photograph below) has been reported as the cause of 17% of acute urticaria cases in children. [12] Urticaria has also been reported with chronic parasitic infections. [13]
In acute forms of urticaria and angioedema, a history of the events surrounding the outbreak is the most important information that can be obtained. Here are three common questions your allergist may inquire about:
This oral antihistamine can reduce the rash and other symptoms, like itching, by working from the inside out. Be sure to follow the dosage instructions on the package. The medicine usually kicks in within an hour, and you should see symptom reduction the same day.

“cures for urticaria giant urticaria”

These types of antihistamines usually work well and do not cause drowsiness. Occasionally an older antihistamine which makes you sleepy may be useful, particularly if the itch keeps you awake at night. In this case an antihistamine such as chlorphenamine may be useful.
When hives are severe, some doctors may suggest a course of oral steroids. Some common side effects of oral steroids include acne, blurred vision, cataracts or glaucoma, easy bruising, difficulty sleeping, high blood pressure, increased appetite and weight gain, increased growth of body hair, insomnia, lower resistance to infection, muscle weakness, nervousness, osteoporosis, stomach irritation or bleeding, sudden mood swings, puffy face, water retention, swelling and worsening of diabetes. (13)
Omalizumab, or Xolair, is an injectable drug that blocks immunoglobin E, a substance that plays a role in allergic responses. It can reduce symptoms of chronic idiopathic urticaria, a type of hives of unknown origin that can last for months or years.
When we’re exposed to a stressful situation, our bodies prepare for confrontation. This “fight or flight” response is controlled by our hormones and nervous system and dates back to prehistory, as we prepared to fight or flee our stressor.
We all experience stress at some time in our lives. In small amounts, stress can help you. For stress might keep you alert when studying for a test, or give you a boost of adrenaline when faced with a deadline. But stress is also a warning sign that something is wrong. It can set off a number of physical, cognitive and emotional symptoms that make it more difficult to deal with a situation. When you ignore the signs of stress, it may in some cases, grow stronger and can cause you to break out in hives.
Your body runs like a machine. I like to use the analogy of your body being like a car. You need to care for it, fuel it, get it checked up regularly, and do everything you can to prolong it’s life. When there’s an issue with your car’s engine, your check engine light pops up. That light is your car telling you, “Hey there’s something wrong with me. You might want to check it out”. Similarly, your body gives out physical signs when something’s not right. If you have an unhealthy diet, you have less energy. If you’re smoking a pack of cigarettes a day, you start to have trouble breathing. And if you’re too stressed out, you can develop Stress Hives (also known as stress Urticaria).
Drugs that block histamine-1 (H1) receptors (antihistamines) are the primary treatment for urticaria. The use of both H1 and H2 receptor blockers has been recommended but has not been proven more effective. Patients should avoid identified allergens. Doxepin, calcium channel blockers, or immunosuppresive drugs may be needed for symptoms that are not well controlled with antihistamines. Known triggers of urticaria should be avoided.
Frequently, more than one type of physical urticaria may occur in a patient and it may be difficult for the individual to avoid the triggering stimulus/stimuli. The physical urticarias may, therefore, be difficult to treat and may be long-lasting.
Unfortunately there are no known specific therapies for HUV. The regime of prescription steroids and other immunosuppressive drugs aims to dampen the body’s production of anti-C1q antibodies.[3] However, this again renders the individual immunocompromised.
urticaria pigmento´sa the most common form of mastocytosis, occurring primarily in children, manifested as persistent pink to brown macules or soft plaques of various size; pruritus and urtication occur on stroking the lesions.
About 20% of people are affected.[2] Cases of short duration occur equally in males and females while cases of long duration are more common in females.[4] Cases of short duration are more common among children while cases of long duration are more common among those who are middle aged.[4] Hives have been described at least since the time of Hippocrates.[4] The term urticaria is from the Latin urtica meaning “nettle”.[5]
Urticarial vasculitis carries a good prognosis, with most occurrences resolving in months to years. Urticarial vasculitis associated with hypocomplementemia is associated with a greater incidence of coexisting disease (ie, angioedema, connective-tissue disease [primarily SLE], chronic obstructive pulmonary disease).[10, 11] Mortality is rare. Some cohorts have demonstrated systemic involvement in roughly half of the patients, including musculoskeletal and ocular complications.[12]
If your hives are uncomfortable or disrupting your life, consider seeing an allergist or physician to determine the underlying cause, especially if you have never had hives before. In many cases, a doctor can prescribe or recommend an over-the-counter medication that can help relieve your symptoms or calm down your hives as they occur.
Clinical Context:  Colchicine is an alkaloid extract that inhibits microtubule formation. It is often used for the treatment of acute gout. Colchicine has been reported effective for urticarial vasculitis. It concentrates well in leukocytes and reduces neutrophilic chemotaxis and motility. Histologically, urticarial vasculitis presents with neutrophil involvement; therefore, colchicine possibly is useful. However, drug’s effect has not been proven in clinical trials.
If the bumps are hard or filled with something other than fluid, they may be a sign of an underlying medical condition. Hives that occur along with peeling of the skin or blisters can be a sign of a serious allergic reaction. If you develop a rash or hives after taking a medication, you should consult your doctor immediately.
Using methods such as deep breathing, yoga, meditation and mindfulness techniques can increase your ability to deal with stressful situations as well as lower your body’s reaction when stress does appear.
In many cases, a single attack of hives is due to an infection or virus and these go away within a few days to a few weeks. Some people get repeated attacks that occur as an allergic reaction to a variety of things (foods, most commonly nuts, chocolate, fish, tomatoes, eggs, fresh berries and milk, insect stings, and medications). In this case, they usually break out within a few hours of the exposure. Usually, the patients figure out the cause by themselves, and they never bother coming to a doctor.
Urticaria occurs when a trigger causes high levels of histamine and other chemical messengers to be released in the skin.These substances cause the blood vessels in the affected area of skin to open up (often resulting in redness or pinkness) and become leaky. This extra fluid in the tissues causes swelling and itchiness.
Antihistamines: The once-daily non-sedating antihistamines are the mainstay of current urticaria treatment, but quadrupling the normal recommended dose is often necessary to obtain symptom control (for example Cetirizine 10 to 30mg, Loratadine 10 to 30mg or Fexofenadine 180 to 540mg).  Once the urticaria is controlled, the dose can slowly be reduced.  Older sedating antihistamines such as Chlorpheniramine, Diphenhidramine or Hydroxyzine may help at night with sleep disturbance from itching.  Tolerance to antihistamines can develop and it may help to periodically rotate through different antihistamines. Ketotifen may be effective in children with its antihistamine and mast cell stabilising properties. If it is necessary to use antihistamines in pregnancy, Chlorpheniramine although sedating, is safest. Stomach ulcer treating Histamine H2 blockers such as Ranitidine or Cimetidine offer additive antihistamine effective if used with conventional antihistamine medication.
If you are constantly worried about what causes hives then you should understand that when you expose your body to excessive stress either for a small amount of time or perhaps a long period of time your own body’s immune system sets out to falter and it starts sending histamine for the body to handle what is causing problem.
Symptoms of chronic urticaria usually resolve, although this can take months or several years. Most people with chronic urticaria manage with appropriate doses of non-drowsy antihistamines. People with severe symptoms interfering with quality of life may be referred to a clinical immunology/allergy specialist or dermatologist for assessment and consideration of additional medications.
Urticaria may be confused with a variety of other dermatologic diseases that are similar in appearance and are pruritic including atopic dermatitis (eczema), maculopapular drug eruptions, contact dermatitis, insect bites, erythema multiforme, pityriasis rosea, urticarial vasculitis, and others. Usually, however, the experienced clinician is able to distinguish urticaria from its mimickers owing to its distinctive appearance (see the images below), intensely pruritic nature, and complete blanching with pressure. [1]
Your doctor will need to ask many questions in an attempt to find the possible cause of hives or angiodema. Since there are no specific tests for hives — or the associated swelling of angioedema — testing will depend on your medical history and a thorough exam by your primary care doctor or dermatologist.
Applying a cold compress to the affected areas of skin can offer some relief from pain and itching. Cooling the skin can decrease the swelling and reduce the histamine content in the bloodstream. Avoid hot baths and showers during an attack of hives as this dilates blood vessels and increases the skin flare up. Stay away from direct sunlight as well as this can aggravate a hives attack.
My name is Mr. Manishkumar Mishra. I have started treatment of Urticaria for my child Mast Kartik Mishra(5 years age) PIN 33099. I started the treatment on 8 th August 2017, since then day by day with the medicines he is feeeling better nowadays. I have observed that there is very good improvement in Urticaria since last 2 months. I did not see any rash of urticaria.

The rash may be triggered by an allergy, or by another factor such as heat or exercise. In most cases the rash lasts 24-48 hours and is not serious. You may not require any treatment; however, medicines called antihistamines can ease the symptoms until the rash clears.
Hives are a common skin condition and rarely require serious medical intervention. Hives have a tendency to resolve on their own, but cause discomfort and pain during an attack. In very rare cases, hives may lead to a marked drop in blood pressure and shock. This is referred to as ‘anaphylactic shock’ and requires immediate medical treatment. Hives are generally caused by an allergic reaction to certain foods, medication or insect bites. There are also some cases of hives where no specific cause is determined. In such situations, changes to diet and lifestyle may help in preventing the condition. Contrary to popular belief, hives are not caused by stress or anxiety.
Aloe vera gel can also be applied over the affected area to reduce inflammation. Aloe vera gel is know to have a cooling effect and this will help provide relief, especially if you have the urge to scratch the inflamed area.
In rare cases, hives or angioedema can be early symptoms of anaphylaxis. Anaphylaxis requires immediate medical attention. If you suspect you are having  an anaphylactic reaction, seek urgent medical treatment. Without proper treatment, anaphylaxis can be deadly.

If you’ve contracted a virus, that could be a cause for hives as well. Dr. Li says hives caused by viruses typically last for six weeks, so if your rash persists for longer, see an allergist to determine another possible cause.
How do you get hives? Hives are not something you can “catch” from anyone. Rather, they are your body’s response to something it ingests or experiences. The cause of hives can be a certain food, drug, infection or stress. You might be surprised to learn that stress is one of the most common causes of acute hives, along with allergies and infectious causes. Hives can literally occur at any age and appear anywhere on the body. It is estimated that one in every five people will be affected by a hives outbreak at some point in his or her life. (2)
Leukotrienes are released from mast cells along with histamine. The medications, montelukast and zafirlukast block leukotriene receptors and can be used as add on treatment or in isolation for patients with CU. It is important to note that these medications may be more beneficial for patients with NSAID induced CU.[42][43]
Past medical history should include a detailed allergy history, including known atopic conditions (eg, allergies, asthma, eczema) and known possible causes (eg, autoimmune disorders, cancer). All drug use should be reviewed, including OTC drugs and herbal products, specifically any agents particularly associated with urticaria (see Table: Some Causes of Urticaria). Family history should elicit any history of rheumatoid disease, autoimmune disorders, or cancer. Social history should cover any recent travel and any risk factors for transmission of infectious disease (eg, hepatitis, HIV).
Winter is not exactly the most popular season, and with good reason for those who live with chronic hives: The cold can trigger a flare-up in some. Besides the weather, other cold-related triggers include chilly foods and swimming pools. For people who are allergic to the cold, full-body immersion in a swimming pool, in particular, can trigger a severe reaction that involves not just hives but allergic shock (anaphylaxis) and loss of consciousness.
An eruption of itching wheals, colloquially called hives, usually of systemic origin; may be due to a state of hypersensitivity to foods or drugs, foci of infection, physical agents (heat, cold, light, friction), or psychic stimuli.
Infections and Infestations: Insect bites, frequent fungal and bacterial infections of the urinary tract, viral infections like hepatitis, worm infestations such as tapeworms and round worms can cause acute allergies.
Urticarial Vasculitis is a form of cutaneous vasculitis characterised by inflammation of the small blood vessels. Urticarial Vasculitis can be classified into three subtypes. All are defined by a measure of the “complement” levels in the blood. The complement system is a set of proteins that contribute to and amplify immune responses. They play a role in some, but not all, autoimmune disorders including some forms of Urticarial Vasculitis.
If sunlight triggers your hives, you’ll probably know within just a few minutes of exposure to one of these three types of light: long-wavelength ultraviolet (UVA), short-wavelength ultraviolet (UVB), and sunlight that doesn’t contain ultraviolet rays, such as sunlight through a window covered with a protective film that blocks UVA and UVB light. Hives triggered by sunlight usually disappear within a day, but in the majority of cases, they recur. Fortunately, sunlight is a rare trigger, and it’s easier to test for than other potential triggers.
Acupuncture is another option for natural hives treatment, especially for chronic hives. It is a holistic health technique that stems from Traditional Chinese Medicine practices. Trained practitioners stimulate specific points on the body by inserting thin needles into the skin. When it comes to hives, acupuncture aims to provide immediate relief from the swelling and itching. Acupuncture also tries to get to the root of the hives, including any underlying imbalances or triggers that are causing the hives. Some common acupuncture points for hives include Spleen 10 (SP 10)  and Large Intestine 11 (LI 11).  One double-blind study placebo-controlled study treated 40 patients with chronic urticaria using either real acupuncture or “sham acupuncture” for three weeks. The subjects treated with real acupuncture experienced partial remissions of symptoms after three weeks. The effectiveness of the acupuncture treatments appeared to increase with each additional treatment. (22)
Simply put, external stressors plus cognitive, behavioral and social stressors have been shown to play a significant role in the intensity of itch, often providing an ever greater correlation than the actual dermatologic disease severity, according to Dr. Howard.
The natural history of urticarial vasculitis depends in part upon the blood complement levels. In cases where these are normal, the prognosis is generally good. In cases where the complements are low, the disease may be more severe. When urticarial vasculitis is related to a disease such as lupus or cancer, its prognosis is often governed by the prognosis of the underlying disease
Insect bites are localised, often clustered in groups of 3–5 lesions, and they appear in crops. Bites persist for days. Close inspection reveals a central punctum. Chronic hypersensitivity to insect bites is often called papular urticaria.
Drugs: antibiotics like penicillin, vaccinations, anti –inflammatory drugs like aspirin and contraceptive pills are just some of the many drugs that can cause an allergic reaction. Animals treated with penicillin secrete a small amount of the drug in their milk, and sensitive individuals may experience a reaction after consuming this milk.
In other words, when a person is stressed, any inflammatory reactions are likely to be more severe in a person who is susceptible to a reaction. In this way, hives, or urticaria, can be linked to stress.
Q. I was diagnosed with chronic urticaria. What is the reason for this condition? I was diagnosed with chronic urticaria last week after more than two months of urticaria (I have more than twenty 1 dollar coin area no my trunk that are red swollen and itchy). when I was younger I had a similar reaction too a bee sting and I was treated with an shoot. Since that one time I never suffered from this kind of symptoms till two months ago. What can be the reason for this condition?
Once you know what triggers your outbreaks, limiting your exposure to these will reduce your risk of developing hives. Keep in mind though that sometimes hives appears to be spontaneous with no known trigger. 
After seeing the video for “Hate to Say I Told You So” on German TV, Alan McGee (Oasis, Creation Records) decided to sign the band to his newly formed Poptones label. Poptones released the ‘best of’ compilation Your New Favourite Band in 2001, which proved to be their breakthrough record, reaching No. 7 in the UK album charts. Following the success of the album, the band re-released singles “Hate to Say I Told You So” and “Main Offender” which reach numbers No. 23 and No. 24 respectively in the UK Singles chart. The band also re-released Veni Vidi Vicious in the US. “The Hives – Introduce the Metric System in Time” was included on the punk rock sampler album Punk-O-Rama Volume 5 from Epitaph Records.[6]
In acute (short-lived) hives, the weals may come and go for a few days or weeks. Rarely, they persist for more than six weeks. Chronic hives is much less common. The weals come and go for months or even years. 
Loratadine is commonly used to treat both acute (sudden) and chronic (long-term) urticaria (hives). It is considered safe to use long-term, but talk to your doctor to make sure you should continue after about six months.
Benadryl (diphenhydramine) is the most commonly used drug for hives, and is available without a prescription. The main side effect of this drug is drowsiness in some people. Other antihistamines (for example, store brands of any drug for hay fever) will also help. When you give Benadryl, give it 3 to 4 times a day until the hives are gone for 12 hours. Use the dosage given on the product.
Pityriasis rosea typically fades without treatment in six to eight weeks. During this time, you can use an OTC anti-itch medication, like diphenhydramine (Benadryl) or cetirizine (Zyrtec) to ease your symptoms.
The clinical history should indicate if a vasculitic process is likely, with the lesions lasting for several days, instead of hours, and being painful or burning, instead of itchy. Patients should be asked about drug treatment and joint, gastrointestinal and pulmonary symptoms. Examination may show purpura or hyperpigmentation at the sites of earlier lesions and, possibly, signs of an associated underlying disease such as SLE. Investigations which may be relevant include skin biopsy to confirm the diagnosis; FBC and ESR; renal and liver function tests; urine analysis; complement C3 and C4 levels and anti-C1q antibodies; ANA and extractable nuclear antigens (ENA) (often positive for Ro/SS-A and La/SS-B if the patient has Sjögren’s syndrome); hepatitis, Borrelia or Epstein–Barr virus serology; immunoglobulins and protein electrophoresis and cryoglobulins and chest X-ray (CXR) and pulmonary function tests if symptoms suggest lung involvement. [Anti-neutrophil cytoplasmic antibodies (ANCA) are rarely found in urticarial vasculitis and if ANCA testing is positive an alternative diagnosis such as Wegener’s granulomatosis or microscopic polyangiitis should be considered.]
Acute urticaria can be divided into two general types, depending on the rate at which hive formation occurs and the length of time it is evident. One type produces lesions that last 1-2 hours and is typically encountered in physically induced hives. The inciting stimulus is present only briefly, and there is prompt mast cell degranulation. Biopsy of such lesions reveals little or no cellular infiltrate. The second type produces a prominent cellular infiltrate, and individual lesions can last as long as 36 hours. This type is encountered with food or drug reactions, delayed pressure urticaria, chronic spontaneous urticaria, and urticarial vasculitis  (click for picture).
A food allergy attack can last for quite a while as the allergen remains within your system and this increases the severity of the reaction. Drink plenty of fluids such as fresh fruit and vegetable juices as this will help to get rid of the allergen and reduce the recovery period.
Get medical help. In rare cases, hives can cause swelling in the throat and can cause an emergency situation that requires epinephrine. Epinephrine can also be used as an EpiPen in those who are severely allergic to a particular substance and require epinephrine to avoid anaphylaxis, which is a severe allergic reaction that may occur with or without the appearance of hives. The symptoms of an anaphylactic reaction include:
This skin disease is common, and it often goes away on its own. It typically starts with a large patch of red, raised skin. This “mother patch” or “herald patch” may be surrounded by small red bumps, or “daughter patches,” that are typically oval in shape.
Immunological: Some hives are caused by changes in the immune system. A typical scenario would be coming in contact with something that causes cells in the immune system to trigger the release of histamine from certain white blood cells called mast cells.
Figure out what’s adding to your stressful feelings and remove or reduce the source. If your stress is from overwork, learn to delegate, especially during allergy season. If your stress is from overextending yourself, rethink your priorities.
My rash ravaged my body after the prednisone ended and I drank a glass of wine…. Big mistake. I thought it was poison ivy but nothing helps. I’m getting it yearly and it follows the nerve paths so if you have some helpful guidance I will check it out.

“treatment for urticarial vasculitis hives on back”

The pathophysiology of urticarial vasculitis is similar to other forms of cutaneous small vessel leukocytoclastic vasculitis. Urticarial vasculitis is a type III hypersensitivity reaction in which antigen-antibody complexes are deposited in the vascular lumina. This reaction results in complement activation and chemotaxis of neutrophils. These cells release various proteolytic enzymes, such as collagenase and elastase, resulting in damage to the vascular lumina. Some authors have speculated that eosinophils may be involved in the early stages of the vasculitic lesions. Patients with hypocomplementemic urticarial vasculitis are more likely to show autoantibodies to C1q and vascular endothelial cells.[6, 7] The presence of antineutrophilic cytoplasmic antibodies is rare. Many patients ultimately prove to have SLE. Other etiologies include drug reactions and parasitic infections.[8]
While there are several different types of hives that can appear as a result of a reaction, most of their signs and symptoms are similar. Bearing that in mind, we have taken the time to put together 10 of the most common signs of hives, so you can be prepared in the event they occur, and can reach out to a medical professional to get to the bottom of it.
Swellings, known as wheals, appear as a rash on the skin. They are usually pink or red, with an oval or round shape. They can range from a few millimeters to several inches across. They be extremely itchy, and they have a red flare around them.
In Chronic Urticaria it is far more difficult to identify a specific cause and the actual trigger in over 50% of cases remains unknown (Spontaneous Urticaria).  We call this urticaria due to unknown cause Chronic “Idiopathic” Urticaria (CIU) or Chronic Spontaneous Urticaria (CSU). Chronic Urticaria may be triggered by generalised illnesses such as autoimmune thyroid disease, collagen joint and vascular disease, chronic parasitic infections, chronic sinusitis, urinary infections, Helicobacter pylori and chronic dental infections. About one third of cases are due to auto-antibodies directed against IgE or the Mast Cell IgE receptor.  Sometimes food additives and preservatives (Benzoate, Sulphites and Artificial dyes) can continuously trigger chronic urticaria, but true food allergy is unlikely to cause Chronic Urticaria.
Evidence of systemic autoimmune disease, including hypothyroidism or hyperthyroidism (autoimmune thyroiditis); hepatitis, renal failure, and polyarthritis (cryoglobulinemia); malar rash, serositis, and polyarthritis (SLE); dry eyes and dry mouth (Sjögren syndrome); cutaneous ulcers or hypopigmented lesions after resolution of urticaria (urticarial vasculitis)
Topical therapies for hives are available but are generally ineffective. They include creams and lotions which help numb nerve endings and reduce itching. Some ingredients which can accomplish this are camphor, menthol, diphenhydramine, and pramoxine. Many of these topical preparations require no prescription. Cortisone-containing creams (steroids), even strong ones requiring a prescription, are not very helpful in controlling the itch of hives.

Hives (AKA urticaria) is not contagious by any means. They are a skin disorder that results in red, sometimes itching patches of raised skin. The patches of skin can be small or large, and generally appear quite fast and disappear on their own within hours or days. They can be as small as a few millimeters and as large as inches, and can even join together to become large areas called plaques. When they join together all over your body, they are generally known as body hives. This form of rash is often quite itchy in nature and can burn. Learn more on our page title “Are Hives Contagious?”
Clinical Context:  Colchicine is an alkaloid extract that inhibits microtubule formation. It is often used for the treatment of acute gout. Colchicine has been reported effective for urticarial vasculitis. It concentrates well in leukocytes and reduces neutrophilic chemotaxis and motility. Histologically, urticarial vasculitis presents with neutrophil involvement; therefore, colchicine possibly is useful. However, drug’s effect has not been proven in clinical trials.
See an allergist, who will try to look for triggers to your hives and may recommend medications to prevent the hives or reduce the severity of symptoms. Whether the treatment is available only by prescription or over the counter will depend on several factors, including how uncomfortable the hives are making you.
The stress and anxiety bought on by an attack of hives can be countered with herbal teas such as peppermint or chamomile tea. These teas also have sedative properties and can help soothe the pain and itching symptoms of hives. Other stress busting activities like yoga and meditation can also help.
I viewers, I was diagnosed officially in March 2015. I’ve SO MANY symptoms! The “diabetic nerve pain”-tho I’m NOT Diabetic! Just LOTS of it! The tingling, & numbness & fatigue and ALL the rest!

Can’t hurt. Let me know if you have any questions! I’ll be Happy to help through my email: zandrasmithon@gmail.com. I don’t want anyone else to die with this hideous disease! God bless.
If your GP thinks that it’s caused by an allergic reaction, you may be referred to an allergy clinic for an allergy test. However, if you’ve had urticaria most days for more than 6 weeks, it’s unlikely to be the result of an allergy.
Urticaria has been reported with infectious diseases. Viral infections associated with acute urticaria include acute viral syndromes, hepatitis (A, B, and C), Epstein-Barr virus, and herpes simplex virus. Streptococcal infection (see the photograph below) has been reported as the cause of 17% of acute urticaria cases in children. [12] Urticaria has also been reported with chronic parasitic infections. [13]

I found that my urticaria arose whenever i ate a particular type of chocolate. This was small chocolate chips found in Biscuits like Hide & Seek / Choconut etc and also when i ate ‘Selbourne’ chocolate. This appears to also happen when i have indigestion problem and i eat this chocolate. Never happens when i eat other chocolates. I get relief by applying a little Axe Oil or PakFahYeow
A single episode of hives does not usually call for extensive testing. If a food allergy is suspected, consider keeping track of what you eat. This will help you discover whether there is a link between what you’re eating and when you break out with hives.
Insect bites are localised, often clustered in groups of 3–5 lesions, and they appear in crops. Bites persist for days. Close inspection reveals a central punctum. Chronic hypersensitivity to insect bites is often called papular urticaria.
Insect venoms, animal danders and/or saliva, penicillin, protease enzymes in biological detergents [6] and latex proteins are other common causes of IgE-mediated urticaria, which again are often identified by the patient. Patients who are latex-protein allergic may also react to a wide variety of foods [7] (Table 2) because of cross-reactivity between the latex protein antigens and food antigens or, if they are highly sensitized, they may develop symptoms after eating foodstuffs which have been handled by workers wearing latex gloves [8].
Physical urticaria: Where the skin is affected by things like cold, heat, sun exposure, vibration, pressure, sweating and exercise. The hives may only be found where the skin was affected can appear within an hour of the exposure.
Antihistamines are also prescribed to treat chronic (lasting longer than 6 weeks) hives. When prescribed for chronic hives, you take this medicine every day to prevent hives from forming. There are many antihistamines on the market. Some make you drowsy, and some do not.

Next, if any obvious triggering factors have been identified from the history these should be eliminated, wherever possible. For example, specific food triggers should be excluded from the diet; treatment with aspirin, NSAIDS and codeine should be stopped; physical triggers such as coldand heat should be avoided whenever possible; and clinical thyroid disease or underlying infection treated. Anti-pruritic, cooling skin lotions such as calamine lotion or 1% menthol in aqueous cream may help to relieve itching.
Lastly, some forms of urticaria and angioedema are related to other diseases, such as autoimmune diseases (for example, lupus and rheumatoid arthritis), certain cancers, chronic infections (for example, viral hepatitis, and some hereditary forms.

Chizzola maculae is a very specific skin lesion due to fluoride exposure. The size of a coin, these lesions may resemble small blue bruises or be wholly pink. Doctors George Waldbott and V. A. Cecilioni named the lesions after a town in Italy, where they were common in young women and children.[17] According to Waldbott, chizzola maculae are early symptoms of fluoride intoxication.[18][19]
There are two forms of heat urticaria. The more common form is also called cholinergic urticaria or generalized heat urticaria. In this form, it occurs when the body temperature is raised such as in a hot bath or shower, from a fever or exercise. The outbreak begins with a few small hives and gradually become more widespread. If the reaction is very severe, the wheals will run together, leading to a drop in blood pressure and loss of consciousness. Cholinergic urticaria is helped by antihistamines given regularly in severe cases or intermittently upon exposure to milder cases.
Diet plays a very important role in the treatment of urticaria, especially in the case of a food allergy. The first step in planning your diet for urticaria is to avoid the food that is causing the reaction. If you are unsure as to what food caused your reaction, you would need to make a list of all the foods that you have consumed in the last 24 hours and avoid all of them if possible. Try to recall if your diet in the last 48 hours included foods that you do not usually consume. Take away food, especially Chinese food is often associated with food allergies due to the spices and condiments that are used to prepare them. 
Urticarial vasculitis can be treated similarly but other agents (that are typically less effective for CSU) may be tried, such as dapsone, hyroxychloroquine, or colchicine. Hydroxychloroquine can be particularly helpful for the treatment of the hypocomplementaemic urticarial vasculitis syndrome. The various types of urticarial vasculitis account for less than 1% of all chronic urticarias.
CIU & You is an educational program focused on supporting the specific needs of people suffering with chronic idiopathic urticaria. Developed in partnership with the Asthma and Allergy Foundation of America (AAFA), and made possible by Novartis Pharmaceuticals Corporation and Genentech, CIU & You aims to educate patients and encourage patients to better communicate their symptoms to their healthcare provider.
Drugs that have caused allergic reactions evidenced as hives include codeine, dextroamphetamine,[7] aspirin, ibuprofen, penicillin, clotrimazole, trichazole, sulfonamides, anticonvulsants, cefaclor, piracetam, vaccines, and antidiabetic drugs. The antidiabetic sulphonylurea glimepiride, in particular, has been documented to induce allergic reactions manifesting as hives. Drug-induced hives has been known to have an effect on severe cardiorespiratory failure.[medical citation needed]
Other forms of chronic urticaria include the physical urticarias, in which the rash is triggered by stimuli such as heat, cold, sunlight, pressure, and vibration. It is important to note that many forms of urticaria get worse with heat (such as from hot baths, exercise or wearing too much clothing) and pressure (such as around tight waistbands from clothing).
The cause of most cases of urticarial vasculitis is unknown. It may be associated with a number of diseases, especially systemic lupus erythematosus, rheumatoid arthritis and Sjögren’s syndrome. Some cancers, including leukemias, colon and pancreatic, and infections like Hepatitis B and C can cause this form of vasculitis. So can some drugs, including antibiotics, ACE inhibitors used for treating high blood pressure, and certain diuretics.
Other natural remedies for hives include applying aloe vera gel on the affected skin or making a paste with oatmeal and cornstarch and coating the rash with it. Keep this paste on for thirty minutes before washing it off with water. Lotions containing aloe vera as an ingredient are also effective.
