There are many patterns of hives with different underlying causes. In order to cope with urticaria, it is important to understand exactly which form of urticaria exists because the treatment is directly affected by the diagnosis. It is important to note that there are other skin conditions due to allergy, one of the most common being eczema or dermatitis. Moreover, allergic skin conditions are common and plague people the world over, but not all skin problems are allergic in origin. See a qualified medical for diagnosis and treatment.
If these agents fail, colchicine, hydroxychloroquine, or dapsone may be effective. If all other treatment modalities have failed or if the patient has systemic involvement, consider initiating treatment with glucocorticoids. If the patient requires long-term treatment with corticosteroids, consider every-other-day dosing of the steroid or the addition of azathioprine as a steroid-reducing agent. Response to newer agents, including mycophenolate mofetil[20, 21] and rituximab, has been reported in the literature. Rituximab-based treatment can provide higher response rates compared with corticosteroids and conventional immunosuppressive agents, which supports its use in relapsing, refractory, or severe disease.[12]
If the urticaria remains unresponsive to high-dose H1 anti-histamines, H2 anti-histamine treatment, at standard dosage, may be added. This is an off-licence use of these drugs, but there is evidence that combined H1 and H2 anti-histamine treatment gives better symptom control than H1 anti-histamine treatment alone [52,53]. Unlike cimetidine, ranitidine does not inhibit oxidative hepatic drug metabolism and so has less potential to cause drug interactions.
The symptoms of a stress rash include red bumps and swollen areas on your skin that seem to appear randomly. Quite often, they are incredibly itchy and can also have a prickly or burning sensation when touched. Don’t scratch them! Don’t be surprised if your stress rash appears on your face, neck and chest, as that is where I get mine. Others get them on their arms and legs. Stress hives can be as small as a pencil eraser or as BIG as a dinner plate! Often the smaller hives meld with the bigger hives to make one big messy outbreak that looks absolutely terrible. However, with the right over the counter medication, like OxyHives, you’ll be able to get rid of them in no time.
However, says Anand, “we don’t know if the disease causes urticaria or if the person’s propensity to have an autoimmune reaction causes it. But if we don’t find any triggers when we test for allergens, then we look for an underlying infection or autoimmune disease.” Anand adds that treatment for that condition can help clear the hives.

What we do know: hives, also known as urticaria, can appear anywhere on the body, including your face, torso, arms, legs, and even inside your mouth and ears. They may range in size from as tiny as a pencil tip to as large as a dinner plate. Hives typically crop up when you have an allergic reaction to a substance—pet dander, pollen, latex—triggering your body to release histamine and other chemicals into your blood. That’s what causes the itching, swelling, and other symptoms.  
Special diets appear to have a limited role to play in the management of hives. Unfortunately, it is difficult to predict who will or will not respond to diet on the basis of history or allergy testing. A temporary elimination diet under close medical supervision, followed by challenges may be useful in a small number of cases. 
This list shows the foods that most often cause hives. But an allergy to foods is actually pretty rare, occurring in 1% of hives sufferers. Whether the food additives listed above actually cause hives is controversial. But many people think their hives are caused by food additives and want to try eliminating them.

We classify Urticaria into Acute Urticaria when the rash duration is under 6 weeks and Chronic Urticaria when it persists for over 6 weeks. Physical Urticaria is due to an external physical trigger such as heat, cold, pressure or exercise (also called Inducible Urticaria). While Urticarial Vasculitis is a rare condition associated with underlying auto-immune connective tissue diseases which requires specialist referral.

The common symptoms include a raised, bumpy red rash, with the bumps often looking more like normal skin colour, that is often quite itchy. The raised areas of skin are known as weals, which often fade after a few hours but can sometimes reappear elsewhere on the body.
If your symptoms worsen or last longer than a couple of days, see your doctor. They can identify the cause and provide you with medication to help relieve your symptoms. Understanding what caused the hives is key to preventing future outbreaks.
The most important part of the investigation of a patient with urticaria is to take a detailed history [43]. This should include structured questions about the many possible clinical causes of urticaria (see above); the frequency, timing and duration of attacks; whether the patient has developed more severe allergic symptoms such as angioedema or wheezing in association with the urticaria; and whether there are any symptoms suggestive of an underlying medical condition such as a connective tissue disease and/or urticarial vasculitis. Photographs may be helpful in confirming the diagnosis and patients may have compiled a symptom diary, which is sometimes useful when trying to identify possible triggers for the rash.
In addition, it appears that a large percentage of people without an obvious trigger for chronic hives may actually have an autoimmune disease. With these conditions, the immune system attacks healthy tissue, including the skin. Juvenile rheumatoid arthritis, lupus, and dermatitis herpetiformis (associated with celiac disease) are among those that may cause hives.
urticaria pigmentosa, juvenile urticaria pigmentosa present at birth or in the first few weeks of life, usually disappearing before puberty, taking the form of a single nodule or tumor or of a disseminated eruption of yellowish brown to yellowish red macules, plaques, or bullae.
If that doesn’t work, some doctors may try a short course of cortisone (steroids) to clear the hives completely. Then the patient can maintain the effect with the much safer antihistamines, since steroids have significant side effects if used long term.
Cold-induced urticaria: Urticaria occurs after exposure to cold, cold objects or cold water. The urticaria is usually localised to exposed areas but sudden total body exposure, as in swimming, may cause a drop in blood pressure and can rarely be fatal.
Sometimes hives go away on their own without treatment. Otherwise, hives can generally be treated at home. The most common treatment for hives is an over-the-counter (OTC) antihistamine. Antihistamines can relieve symptoms like itching. You can find a great selection of OTC antihistamines here.
Mechanisms other than allergen-antibody interactions are known to cause histamine release from mast cells. Many drugs, for example morphine, can induce direct histamine release not involving any immunoglobulin molecule. Also, a diverse group of signaling substances, called neuropeptides, have been found to be involved in emotionally induced hives. Dominantly inherited cutaneous and neurocutaneous porphyrias (porphyria cutanea tarda, hereditary coproporphyria, variegate porphyria and erythropoietic protoporphyria) have been associated with solar urticaria. The occurrence of drug-induced solar urticaria may be associated with porphyrias. This may be caused by IgG binding, not IgE.
The Hives are a Swedish rock band that rose to prominence in the early 2000s during the garage rock revival. Their mainstream success came with the release of the album Veni Vidi Vicious, containing the anthem “Hate to Say I Told You So”. The band have been acclaimed by music critics as one of the best live rock bands in current music.[1][2]

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.

It is not clear from the question if the patient had febrile non-hemolytic reaction or urticarial reaction, since fever is described as the sign and symptom, while the patient had continuation of blood transfusion following medication with Benadryl (antihistaminic), which is usually given for an urticarial reaction.
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.
The most prominent symptom of urticaria is swelling of the surface of the skin. The pattern of the hives may get larger, spread out, or join together to alter the pattern as the condition progresses and spreads over a larger surface area. They may also disappear and reappear within a few minutes or within hours. If you press the center of a hive, it affects the entire hive, and it will turn white. An outbreak of hives generally escalates very rapidly and it is possible for the bumps to appear and spread over your skin within 30 minutes. This rapidity is considered to be one of the most characteristic of all urticaria symptoms. The raised patches of skin will be extremely itchy while the rest of your skin may be very sensitive. The welts caused by urticaria may be either pin point, or patch size in area and in some cases it can cause a secondary skin condition known as Angioedema. Single hives that cause much pain will last more than a day and leave bruise marks as they are likely to be a more serious condition known as urticarial vasculitis. Hives that are caused by friction will be linear in appearance and are of a benign condition and require little or no urticaria treatment apart from eliminating the source of friction.

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 and 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.
Hives can be caused by an allergic reaction to foods, drugs, insect bites, infections or substances which can cause other allergic reactions. However not all cases are caused by allergy; frequently they are caused by viruses. It can sometimes be extremely difficult to find the cause. Triggers include medications, food, viruses, latex, heat, cold and direct exposure to sun. If the cause is known, the trigger should be avoided.
Pronounced “ur-ti-kair-ee-uh,” this is the medical term for hives. Urticaria appear as red, itchy bumps or welts on the skin that can appear anywhere on the body. A red hive will turn pale when pressed in the center, which is called “blanching.” For every 10 people whose hives are chronic, at least seven of them have CIU.
The cause of chronic hives can rarely be determined.[28] In some cases regular extensive allergy testing over a long period of time is requested in hopes of getting new insight.[29][30] No evidence shows regular allergy testing results in identification of a problem or relief for people with chronic hives.[29][30] Regular allergy testing for people with chronic hives is not recommended.[28]

Cold urticaria is usually idiopathic, but it may occur patients with cold-dependent antibodies, such as cryoglobulins or cold agglutinins [15] and there is a very rare familial form of cold-induced urticaria which is dominantly inherited [16]. Patients develop itching, erythema and urticaria affecting that part of the body which has been exposed to cold. Symptoms may worsen as the exposed area is warmed. Total immersion in cold water can cause severe symptoms with hypotension and patients should be warned that swimming in cold water can be dangerous. Local heat-induced urticaria is rare [17]. Some unfortunate patients may develop urticaria on exposure to both heat and cold [18]. Generalized heat-induced urticaria or ‘cholinergic’ urticaria is caused by exercise, sweating and hot showers or baths. The term ‘cholinergic’ is used because sweat glands are innervated by cholinergic nerve fibres. The urticarial lesions are often small and intensely itchy. Very severe cholinergic urticaria may cause hypotension and therefore there may be some overlap with the clinical syndrome of exercise-induced anaphylaxis [19,20].

Urticaria results from the release of histamine, bradykinin, kallikrein, and other vasoactive substances from mast cells and basophils in the superficial dermis, resulting in intradermal edema caused by capillary and venous vasodilation and occasionally caused by leukocyte infiltration.
In many cases, mild hives won’t need treatment and will go away on their own. If a definite trigger is found, avoiding it is part of the treatment. If the hives feel itchy, the doctor may recommend an antihistamine medicine to block the release of histamine in the bloodstream and prevent breakouts.
Immunotherapy: Allergy shots help only if a person has hives because of what they breathe. These people can be successfully desensitized. Cross reacting proteins from inhalants that are also found in foods can help drop the degree of reactivity to those foods.

A drug used for psoriasis and kidney transplants, cyclosporin, is almost always effective in clearing even the most severe cases of chronic hives at low doses. However, it causes significant side effects if taken for a long time.
That said, no two people respond to stressful events in the same way either. What may be a source of emotional excitement for you may cause fear for a friend. For instance, you may love to skydive on your weekend while your best friend cringes even thinking about flying in an airplane. That’s because we all perceive and respond to stressors differently. Again, it’s the inappropriate responses that influence your health and may influence your allergy symptoms.

She’ll also ask about the foods you eat and if you have pets, to see if an allergy is to blame. She may check for other illnesses or conditions that could be causing the hives, like an overactive or underactive thyroid.
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]
“Sometimes, it’s just a matter of planting a seed that somatic symptoms respond to stress reduction techniques that can motivate a patient to pursue treatment,” Dr. Howard says. “This can also lead to diagnosis and treatment of previously unidentified psychiatric comorbidities such as mood and anxiety disorders.
“My allergist tested me for everything but we still couldn’t figure out a cause for the hives. It was so frustrating to keep searching for a cause. And as much as I was seeking answers, I wasn’t getting any, and wasn’t getting any relief either. Weeks passed, but the hives didn’t. Friends and family offered suggestions and their own explanations but they didn’t understand what I was going through.
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 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.

Hives causes can be avoided; sometimes only through trial and error. To do this, keep a journal of all the foods, medications and illnesses or activities that you or your child has prior to getting the hives. After a few cases of hives, your hives causes will be seen in the similarities between the cases. If you always get hives after being out in the direct sunlight for a few hours, your physical hives will then have a known allergen. In this way, you can avoid the allergen and be able to avoid the hives as well.
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.
If your reaction involves swelling of your tongue or lips, or you have trouble breathing, your allergist may prescribe an epinephrine (adrenaline) auto-injector for you to keep on hand at all times. These can be early symptoms of anaphylaxis, a potentially fatal allergic reaction that impairs breathing and can send the body into shock. The only treatment for anaphylaxis is epinephrine. If you develop hives and your injector is not nearby – or if using the auto-injector doesn’t cause the symptoms to immediately improve – go to an emergency room immediately. You should also go to the emergency room after using an auto-injector.
Oral steroids:  Although Prednisone  (at least 30mg meticorten daily) is most effective in the short term for rapid symptom control, with long term use will it lead to undesirable side effects and problematic recurrent urticaria on withdrawal. Occasionally long term alternative-day regimens may be necessary to control chronic recalcitrant urticaria.
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.
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.

Patients who have angioedema involving the oropharynx or any involvement of the airway should receive epinephrine 0.3 mL of 1:1000 solution sc and be admitted to the hospital. On discharge, patients should be supplied with and trained in the use of an auto-injectable epinephrine pen.
“Chronic idiopathic hives are itchy red welts that persist for at least six weeks and have no known cause,” says Miriam Anand, MD, an allergist with Allergy Associates and Asthma in Tempe, Arizona. The condition is marked by periods of exacerbation and remission, and for many who have it, the hives may persist for more than five years.
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.
Glucocorticoids are often the treatment of choice. However, given their long-term adverse effect profiles, they are used only for significant cutaneous disease or systemic involvement. For long-term treatment, a combination of prednisone and another medication may be required.
Angioedema is swelling of the deeper tissue that sometimes occurs with hives. Like hives, angioedema can occur on any part of the body. When it occurs around the mouth or throat, the symptoms can be severe, including airway blockage.

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.
An important variant to mention is urticarial vasculitis, which on initial presentation presents like urticaria but the lesions are non-migratory, last for more than 24 hours and resolve with postinflammatory hyperpigmentation.
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.
The most common form of mastocytosis, maculopapular cutaneous mastocytosis is also called urticaria pigmentosa. Itchy brown patches or freckles on the skin are due to abnormal collections of mast cells.
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.
Hives, also known as urticaria, is a kind of skin rash with red, raised, itchy bumps.[1] They may also burn or sting.[2] Often the patches of rash move around.[2] Typically they last a few days and do not leave any long-lasting skin changes.[2] Fewer than 5% of cases last for more than six weeks.[2] The condition frequently recurs.[2]
Stress occurs when forces from the outside impinge on the individual. Stress is a normal part of life. However, over-stress, can be harmful. There is now speculation, as well as some evidence, that points to the abnormal stress responses as being involved in causing various diseases or conditions.
Other medical conditions that can cause pruritus (usually without rash), such as diabetes mellitus, chronic renal insufficiency, primary biliary cirrhosis, or other nonurticarial dermatologic disorders
Genetics. Hereditary angioedema is a rare inherited (genetic) form of the condition. It’s related to low levels or abnormal functioning of certain blood proteins that play a role in regulating how your immune system functions.
You should also avoid using irritating moisturizers or lotions. When in doubt, opt for a formula that targets sensitive skin, such as these options. Applying immediately after bathing may also help soothe the itch.

For some cases of urticaria, especially chronic urticaria, no cause can be found, despite exhaustive efforts. This is known as idiopathic urticaria, [2] although most of these are chronic autoimmune urticaria as defined by a positive autologous serum skin test (ASST). [9]

“cholinergic urticaria cure -viral hives in adults”

Histamine and other proinflammatory substances are released from mast cells in the skin and tissues in response to the binding of allergen-bound IgE antibodies to high-affinity cell surface receptors. Basophils and other inflammatory cells are also seen to release histamine and other mediators, and are thought to play an important role, especially in chronic urticarial diseases.
Other common causes are food, medication, chemicals such as acetone, a polymer such as latex, an viral, fungal, or bacterial infection, pet hair or dander, plants, and physical stimuli such as pressure, temperature, and sun exposure.[5]

A viral infection such as a cold or flu can trigger an urticarial rash in some people. (You react to the virus.) A mild viral infection which causes few other symptoms is probably a common trigger of an urticarial rash that develops without an apparent cause.

Examination of bedding and the children’s play areas for insects may provide a clue to the cause. If insects are found, they must be eliminated by insect repellant or fumigation, and pets should be washed. These bugs are usually not visible to the naked eye. Hanging the bedding in the hot sun may rid these of the bedbugs.
Hives, also known as urticaria, are a type of skin rash that are the result of an allergic reaction to a substance, called an allergen, in the environment. Although the cause of hives is not always known, they are often a response to the body releasing histamines, which it does when you have an allergic reaction to food, medicine, or other allergens. Histamine is also sometimes the body’s response to infections, stress, sunlight, and changes in temperature. Hives typically manifest as small, swollen, itchy, red areas on the skin that may occur singularly or in clusters. Left untreated, hives usually fade within a few hours, but new ones may appear in their place.[1] If you want to try to cure your hives at home, there are many different natural remedies to treat your hives.

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 is a common skin disease characterised by itching weals or hives that can appear anywhere on the surface of the skin. Weals may be pinpoint in size or several inches in diameter. Most sufferers experience hives continuously or intermittently for less than six weeks, but they may last longer (when they are then called ‘chronic’). Urticaria can also be accompanied by angioedema (swelling of a deeper layer of the skin). There are several varieties of urticaria, but the most common forms are acute urticaria and chronic urticaria. Common causes of acute urticaria are infections and adverse reactions to medications and foods, whereas in chronic urticaria the cause is often unknown. Intense itching is common, and it can lead to disturbed sleep and even depression, having a serious impact on a person’s quality of life. As the face and other exposed body parts can be affected, hives and angioedema can prove embarrassing for the individual.
Urticarial vasculitis is a form of vasculitis that affects the skin, causing wheals or hives and/or red patches due to swelling of the small blood vessels. It has two forms: One with normal levels of proteins called complements; the other with low levels of complements; it’s called hypocomplementemic vasculitis.
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.
Antileukotrienes (eg, montelukast), which may provide additional benefit in some selected patients when combined with an H1 antihistamine; there is little evidence that they are effective as monotherapy.
Acute urticaria and/or angioedema are hives or swelling lasting less than 6 weeks. The most common causes are foods, medicines, latex, and infections. Insect bites or a disease may also be responsible.
To do a skin patch test, simply apply a small amount of the product to an unaffected area of skin. If you can, apply to the inside of your forearm. If you don’t experience any irritation within 24 hours, it should be safe to apply to any hives.
Urticaria affects almost 20 percent of the population but the majority of the time, the cause is unknown (idiopathic). Even so, it is a good idea to try to find the trigger so you can possibly avoid it in the future.
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]
Everyone reacts to stress differently. You might experience only a few of these signs or you might notice that more signs develop, especially when you don’t address your stress. Paying attention to your body’s reaction to stress can help you address it immediately, instead of waiting for stress cause you to break out in hives.
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.
A rare autoimmune disease characterized by recurrent urticaria (nettle rash), first described in the 1970s. There is no defined paradigm for the syndrome aetiology and severity in progression. Diagnosis is confirmed with the identification of at least two conditions from: venulitis on skin biopsy, arthritis, ocular inflammation, abdominal pain or positive C1q antibodies to immune complexes.[3] It is this last category, anti-C1q antibodies, that all HUV patients test positive for.[4] In vitro experiments and mouse models of the disease have not thoroughly determined the link between these antibodies and the disease, even though the link is so pronounced.
Hives are welts on the skin that often itch. These welts can appear on any part of the skin. Hives vary in size from as small as a pen tip to as large as a dinner plate. They may connect to form even larger welts.

A. As was said before chronic urticaria is a symptom of many problems. I once took NSAIDs for knee pain and I started to itch myself. It took my doctor 3 weeks to understand that I was allergic to this specific drug. I also know that tomatoes can cause me an allergic reaction. Try to think is there anything new in your life? Tell it to the GP maybe he will be able to tell you if this is the reason for your symptoms.
The autologous serum skin test is sometimes carried out in chronic spontaneous urtciaria, but its value is uncertain. It is positive if an injection of the patien’s serum under the skin causes a red weal.
If your reaction involves swelling of your tongue or lips, or you have trouble breathing, your allergist may prescribe an epinephrine (adrenaline) auto-injector for you to keep on hand at all times. These can be early symptoms of anaphylaxis, a potentially fatal allergic reaction that impairs breathing and can send the body into shock. The only treatment for anaphylaxis is epinephrine. If you develop hives and your injector is not nearby – or if using the auto-injector doesn’t cause the symptoms to immediately improve – go to an emergency room You should also go to the emergency room after using an auto-injector.
An allergic reaction marked by multiple discrete swellings on the skin (wheals) that are intensely itchy and last up to 24 hr. The wheals appear primarily on the chest, back, extremities, face, or scalp. Synonym: hives See: illustration; allergy; angioedema
This process is caused by several mechanisms. The type I allergic IgE response is initiated by antigen-mediated IgE immune complexes that bind and cross-link Fc receptors on the surface of mast cells and basophils, thus causing degranulation with histamine release. The type II allergic response is mediated by cytotoxic T cells, causing deposits of immunoglobulins, complement, and fibrin around blood vessels. This leads to urticarial vasculitis. The type III immune-complex disease is associated with systemic lupus erythematosus and other autoimmune diseases that cause urticaria. [15]

Angioedema is swelling in the deeper layers of a person’s skin. It’s often severe and is caused by a build-up of fluid. The symptoms of angioedema can affect any part of the body, but usually affect the:
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.

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.
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.

The cold type of urticaria is caused by exposure of the skin to extreme cold, damp and windy conditions; it occurs in two forms. The rare form is hereditary and becomes evident as hives all over the body 9 to 18 hours after cold exposure. The common form of cold urticaria demonstrates itself with the rapid onset of hives on the face, neck, or hands after exposure to cold. Cold urticaria is common and lasts for an average of five to six years. The population most affected is young adults, between 18 and 25 years old. Many people with the also suffer from dermographism and cholinergic hives.[citation needed]
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.
Case studies of individuals with HUV have also highlighted other potential complicating factors which it seems the anti-C1q antibodies play a role in. This can mean in some cases the deposition of large immune complexes in the kidney which cannot be cleared by the usual cells of the immune system (e.g. macrophages which are unable to bind the Fc portion of the C1q antibody), leading to further complications.[4] This it seems is rare, but can occur when a pre-existing renal condition is apparent. Also, there has been some speculation as to an additional autoantibody against an inhibitor protein (in the complement pathway) named C1-inhibitor. The inhibition of C1-inhibitor leads to over-activation of the complement pathway and one protein that builds up controls angioedema (vessel – swelling),[4] resulting in excess water building up under the skin (the weal appearance).
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.
Cases of urticaria and angioedema can be acute, lasting less than 6 weeks, or chronic, lasting more than 6 weeks. The length of symptoms can often be a clue as to the cause of the symptoms. For example, the most common cause of acute urticaria and angioedema in children is viral infections.
Allergy shots are given to increase your tolerance to allergens that cause allergy symptoms. At the beginning, allergy shots will be administered once or twice a week for several months. The dose is increased each time until a maintenance dose is reached. Side effects of allergy shots include itchy eyes, shortness of breath, runny nose, tight throat, redness, swelling, and irritation.

Acute urticaria, which is an allergic (IgE-mediated) reaction, is common in both children and adults. This type of urticaria is a self-limiting process that occurs when mast cells in the skin are activated, degranulate, and secrete histamine, leukotrienes, platelet activating factor (PAF), enzymes such as tryptase and chymase, cytokines, and chemotactic cytokines (chemokines). When an allergen (for example, a food) to which the person is allergic arrives via the bloodstream to mast cells in the skin, it binds to the IgE, and the mast cells become activated, and degranulate. Allergens that can result in acute urticaria include foods, drugs (particularly antibiotics such as penicillin), and venoms from bee, wasp, yellow jacket, hornet, or fire ants. Virtually any allergen that can be disseminated throughout the body, and to which there is an IgE response, has the potential to cause generalized urticaria.
I have heard of him before, but after watching the documentary “Last Days of Left Eye” I was turned on to the full story about Dr. Okaben He is a man who has the Cure for AIDS, Cancer, Sickle Cell, Herpes,warts,lupus, Diabetes and every kind of illness, through a whole foods vegetarian diet and natural herbs, what he calls Electric Foods. He never went to school, college or medical school but has thousands of testimonials of healing people with HIV and AIDS, Cancer and several other illnesses. Lisa “Left Eye” Lopes of TLC was cured of Herpes by him and she was so moved by his knowledge that she went on to spread the word about him in every way she could. She also opened a Cultural/Healing Center for Children in Honduras before she passed away tragically. This all inspired me that i had to contact Dr. Okaben, because i was having herpes which could not be cure but was only managed, when i contacted Dr. Okaben, he sent me some herbs which i took, and now i can tell you, i have be totally cured of Herpes, Please if you have any form of illness especially STD,hemorrhoids,Infertility,HIV etc. you can contact him on.

The initial medical treatment for urticaria is a standard dose of a second-generation H1 anti-histamine. These drugs penetrate the blood–brain barrier to only a slight extent and so cause fewer central nervous system side effects than the older first-generation anti-histamines, although symptoms such as sedation and psychomotor impairment may still occur. Seven such anti-histamines are licensed for use in the United Kingdom: Cetirizine, desloratidine, fexofenadine, levocetirizine, loratidine and mizolastine, which are all given once a day, and acrivastine which is given three times a day, and may therefore be less effective and convenient to use. Cetirizine and levocetirizine [49] and loratidine [50] may have clinically useful ‘anti-inflammatory’ properties at therapeutic doses. Cetirizine may cause drowsiness in some patients and mizolastine is contra-indicated in patients with cardiac disease; prolonged Q-T interval; or severe liver disease. Dose reductions may be needed if there is renal impairment. Clinical response and tolerability may be better with one second-generation H1 anti-histamine than another, so if symptoms are not well controlled or the patient notices side effects with the first drug chosen, a second drug should be tried. Often, symptom control is improved if the dose of anti-histamine is increased to twice daily. This is above the licensed recommended dose; however, ‘off-label’ dosages are recommended widely [44,45,51]. A night-time dose of one of the older first-generation, sedating H1 anti-histamines, such as chlorphenamine or hydroxyzine, may help patients to sleep. Empirically, anti-histamine treatment is usually prescribed for 3–6 months (or longer if the patient has angioedema associated with the urticaria) and is tailed off gradually. Episodic urticaria may be treated with stat doses of anti-histamines as required.
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.
Sulfone antibiotics are used for infectious diseases (eg, leprosy); however, sulfones are effective in inflammatory diseases. The mechanism of action may involve inhibiting free radical formation by neutrophils. In most case reports, these medications are effective only in purely cutaneous forms of urticarial vasculitis.

“what hives look like _multivariate”

Allergic reactions, particularly to foods and medications, are another common cause of acute hives. Allergies only cause about 5 percent to 10 percent of chronic hives cases. Pet allergies are usually to blame; pollen, mold, and dust mite allergies cause chronic hives only in rare instances.
Though we may not fight wild animals anymore, there are still “wild animals” facing us daily in the form of arguments, a phone that won’t stop ringing, and perpetually full in-boxes. Now when you add miserable allergy symptoms, you’ve got a recipe for disaster — unless you take time to do something for stress relief.
The most popular treatment for relief from hives is an over-the-counter medication that contains antihistamine. These drugs help fight against an attack of hives and counter the release of histamine from the skin cells that causes the rash. However, antihistamines tend to have side effects such as drowsiness, especially in children. If you prefer an alternative hives treatment, there are several home remedies for hives that are not only effective but safe as well. Do keep in mind that not all home remedies are subjected to scientific testing and results can therefore vary considerably. Some popular methods of home treatment for relief include:
Lin RY, Curry A, Pesola GR, Knight RJ, Lee HS, Bakalchuk L, et al. Improved outcomes in patients with acute allergic syndromes who are treated with combined H1 and H2 antagonists. Ann Emerg Med. 2000 Nov. 36(5):462-8. [Medline].
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.
Protect yourself from pollen. There are some cases where environmental agents can cause hives. If you react to pollen, avoid being outside in the morning and in the evening when pollen levels are at their highest. Keep your windows closed during these times as well and avoid drying clothes outside. Change into “indoor clothes” as soon as possible and wash your “outdoor clothes” right away.
Seek urgent medical attention for yourself or your child if hives are severe and/or cover a large area of your body, or if you have other symptoms, such as difficulty breathing or a fever. Chronic urticaria or chronic hives should be evaluated by an allergist or immunologist to determine proper hives treatment.
It has been suggested that natural salicylates in foods and food additives (‘E’ numbers), including colourings (azo and non-azo dyes), preservatives (sulphites, nitrates and nitrites), anti-oxidants [butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT)] and aspartame (an artificial sweetener), may cause urticaria [9,10], particularly in patients who develop acute allergic symptoms after taking aspirin (acetylsalicylic acid) or non-steroidal anti-inflammatory drugs (NSAIDs); however, randomized controlled trials are lacking [11]. Skin prick testing and SIgE tests to the foods are negative, as the reaction is not IgE-mediated.

Occasionally, a person will continue to have hives for many years. These hives, called chronic urticaria, can be one of the most frustrating problems dermatologists see in their patients. This is defined as hives lasting longer than 6 weeks. Patients like this come in miserable and worried with this problem, often having seen multiple specialists. Neither the patient nor the doctor can determine the cause of the hives. Patients will often say, “It has got to be something causing these hives.” The truth is hard to accept for some patients.

As far as the physical symptoms, you’ll see red bumps and swelling of the skin. They can develop anywhere on your body and be any size. Some people get breakouts as small as a penny, others get stress hives the size of a dinner plate or larger. Urticaria also has a tendency to spread around your body when you leave it untreated which is why you shouldn’t ignore it.
Treatment guidelines for the management of chronic hives have been published.[37][38] According to the 2014 American practice parameters, treatment involves a step wise approach. Step 1 consists of second generation, H1 receptor blocking antihistamines. Systemic glucocorticoids can also be used for episodes of severe disease but should not be used for long term due to their long list of side effects. Step 2 consists of increasing the dose of the current antihistamine, adding other antihistamines, or adding a leukotriene receptor antagonist such as montelukast. Step 3 consists of adding or replacing the current treatment with hydroxyzine or doxepin. If the individual doesn’t respond to steps 1–3 then they are considered to have refractory symptoms. At this point, anti-inflammatory medications (dapsone, sulfasalazine), immunosuppressants (cyclosporin, sirolimus) or other medications like omalizumab can be used. These options are explained in more detail below.
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.
Hives can also be classified by the purported causative agent. Many different substances in the environment may cause hives, including medications, food and physical agents. In perhaps more than 50% of people with chronic hives of unknown cause, it is due to an autoimmune reaction.[6]
If you suspect your rash is the result of a preexisting condition that you’re currently seeking treatment for, you may benefit from a consultation. Your doctor can confirm your suspicions and take appropriate next steps.
Many parents wait to give the antihistamine until new hives have appeared. This means your child will become itchy again. The purpose of the medicine is to keep your child comfortable until the hives go away. Therefore, give the medicine regularly until you are sure the hives are completely gone.

When an allergic reaction occurs, the body releases a protein called histamine. When histamine is released, the tiny blood vessels known as capillaries leak fluid. The fluid accumulates in the skin and causes a rash.
Hives causes can be avoided; sometimes only through trial and error. To do this, keep a journal of all the foods, medications and illnesses or activities that you or your child has prior to getting the hives. After a few cases of your hives causes will be seen in the similarities between the cases. If you always get hives after being out in the direct sunlight for a few hours, your physical hives will then have a known allergen. In this way, you can avoid the allergen and be able to avoid the hives as well.

Urticaria typically looks like a raised rash that may be a normal skin colour or pinkish or red in colour. The rash may occur anywhere on the body and often starts off as small round spots that quickly enlarge and spread.
Other potential triggers of chronic hives include heat and aggravating your skin by scratching it or putting pressure on it (for example, by wearing tight clothes or sitting on a hard surface). Keeping a diary in which you record when and where your symptoms developed or worsened can help you and your doctor find clues and pinpoint your triggers, says Anand. But if even that doesn’t help, don’t lose heart: For most people, even chronic hives whose cause is unknown gradually disappear on their own over time.

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.
Urticaria, commonly referred to as hives, is the most frequent dermatologic disorder seen in the emergency department (ED). It appears as raised, well-circumscribed areas of erythema and edema involving the dermis and epidermis that are very pruritic. Urticaria may be acute (lasting <6 wk) or chronic (lasting >6 wk). A large variety of urticaria variants exist, including acute immunoglobulin E (IgE)–mediated urticaria, chemical-induced urticaria (non-IgE-mediated), autoimmune urticaria, cholinergic urticaria, cold urticaria, mastocytosis, periodic fever syndromes including Muckle-Wells syndrome, and many others. [2, 10] While acute urticaria is generally related to an exogenous allergen or acute infection, chronic urticaria is more likely to be associated with autoimmunity. [8, 11, 12]
Occasionally, a person will continue to have hives for many years. These hives, called chronic urticaria, can be one of the most frustrating problems dermatologists see in their patients. This is defined as hives lasting longer than 6 weeks. Patients like this come in miserable and worried with this problem, often having seen multiple specialists. Neither the patient nor the doctor can determine the cause of the hives. Patients will often say, “It has got to be something causing these hives.” The truth is hard to accept for some patients.
Urticaria due to the direct effects of physical forces on the skin. Cold temperature (cold urticaria), pressure (pressure urticaria), ultraviolet radiation (solar urticaria), and scratching (dermographism) are some causes of physical urticaria.
Saigal K, Valencia IC, Cohen J, Kerdel FA. Hypocomplementemic urticarial vasculitis with angioedema, a rare presentation of systemic lupus erythematosus: rapid response to rituximab. J Am Acad Dermatol. 2003 Nov. 49(5 Suppl):S283-5. [View Abstract]
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.
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.  
Over half of all cases of chronic idiopathic hives are the result of an autoimmune trigger. Roughly 50% of patients with chronic urticaria spontaneously develop autoantibodies directed at the receptor FcεRI located on skin mast cells. Chronic stimulation of this receptor leads to chronic hives. Patients often have other autoimmune conditions, such as autoimmune thyroiditis, celiac disease, type 1 diabetes, rheumatoid arthritis, Sjögren’s syndrome or systemic lupus erythematosus.[6]
Urticaria (chronic, acute, or both) affects 15-25% of the population at some time in their lives. [22] The incidence of acute urticaria is higher in people with atopy, [22] and the condition occurs most commonly in children and young adults. [23]
There are other rashes that may look like hives, but the fact that they remain stable and do not resolve within 24 hours is helpful in distinguishing them from hives. Such rashes may need to have a small specimen of skin removed and examined under the microscope (biopsy) to accurately determine the nature of the skin disease.
In some people hives are caused by physical triggers, including cold (such as cold air, water or ice), heat, sunlight (solar), vibration, rubbing or scratching of the skin (dermatographism) and delayed pressure (such as after carrying heavy bags.  In other people, exercise (sweating), stress, alcohol, spicy food or coffee may cause symptoms.
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:
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 and 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].

Drugs that can cause hives and angioedema include aspirin and other nonsteroidal anti-inflammatory medications such as ibuprofen, high blood pressure drugs (ACE inhibitors), or painkillers such as codeine.
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.
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 long do hives last? Mild hives can appear suddenly and be completely gone a few minutes later. Other times, hives can last for hours and even several weeks to months. Acute episodes of urticaria last for six weeks or less. Hives that last for six weeks or less are acute hives. Those that remain for more than six weeks are chronic hives. It’s nice to know that the majority of hives cases don’t last longer than 24 hours. (4)

Hi everyone, I’m 39 years old male and I contacted the virus in 2004. I did get bad outbreaks for a while, and used to take valtrax. I hated that medicine, so i stopped it however was having outbreaks several times a year. VERY PAINFUL. A year ago I decided to search for the herpes cure, because I too believe there is one somewhere in this world. I came across zeolite (which i tried but did not cure me) and the H2O2 protocol (ingesting 35% food grade hydrogen peroxide for 30 days, per the books written by people claiming their tests came back negative). I could only do 13 days of that because the taste of the h2o2 was making me sick. So needless to say, that did not help either. As of the past 6 months,until i saw a post in a health forum about a herbal doctor from Africa who prepares herbal cure to cure all kind of diseases and virus including ALS, MND,HIV,Epilepsy, Leukemia, Asthma, Cancer, Gonorrhea etc, at first i doubted if it was real but decided to give it a try, when i contact this herbal doctor via his email, he prepared an herpes herbal portion and sent it to me via courier service, when i received this herbal portion, he gave me step by step instructions on how to apply it, when i applied it as instructed, i was cured of this deadly disease within 7 days, I could not walk or talk understandably before but after i took the herbal cure as he instructed i regained strength in my bones and i could talk properly unlike before, I am now free from the deadly virus, all thanks to Dr. Contact this great herbal doctor via his email drnogaduherbalist@gmail.com
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.
Seek urgent medical attention for yourself or your child if hives are severe and/or cover a large area of your body, or if you have other symptoms, such as difficulty breathing or a fever. Chronic urticaria or chronic hives should be evaluated by an allergist or immunologist to determine proper hives treatment.
Key to the prevention of hives is avoiding known triggers. Take note of when hives appears – is it after you eat certain foods? In times of stress? After playing with your dog or cat (animal dander is a common allergen)? You may need to keep a food diary to identify possible allergens in your diet. 
Vital signs should note the presence of bradycardia or tachycardia and tachypnea. General examination should immediately seek any signs of respiratory distress and also note cachexia, jaundice, or agitation.

Dr. Li says sweating can also signal a breakout for those prone to hives. The sweat itself doesn’t cause hives, but indicates your body heat rising. For some, excess warmth on the skin, from a workout or other body-heat inducing activity, is enough to produce hives. “Even taking a hot shower makes them break out,” Dr. Li says.
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.

If that doesn’t work, some doctors may try a short course of cortisone (steroids) to clear the hives completely. Then the patient can maintain the effect with the much safer antihistamines, since steroids have significant side effects if used long term.

To calm hives and help them vanish that much quicker, make sure you’re not using any products on your body that will only make the inflammation and itching worse. You don’t want to be using anything harsh on your body right now. This includes soaps and other body care products, as well as the detergent you use on your clothing. Opt for natural products free of unhealthy synthetic fragrances and other aggravating ingredients. Another simple way to calm hives is to take a cool bath or shower. You can also use a cool compress on the hives to help relieve any itching. (16)
Urticaria typically looks like a raised rash that may be a normal skin colour or pinkish or red in colour. The rash may occur anywhere on the body and often starts off as small round spots that quickly enlarge and spread.
Chronic idiopathic urticaria is the most common type of CU, comprising up to 90% of all cases of CU. It has been estimated that chronic idiopathic urticaria will affect between 0.6% to 5% of the population during their lifetime. Over half of all cases of chronic idiopathic urticaria are thought to be caused by an autoimmune mechanism. This is supported by the observation that 60% of patients with chronic idiopathic urticaria will have a wheal and flare reaction to intradermal autologous serum injections in the autologous serum skin test (ASST). Approximately 50% of patients with chronic idiopathic urticaria have IgG antibodies that are specific for the high affinity IgE receptor (FcεRI). These autoantibodies activate mast cells in the skin, circulating basophils, and the complement system.  Additional immunological abnormalities described to play a causative role in CU include IgG antibodies directed against IgE antibodies and the low affinity IgE receptor (FcεRII), antiendothelial antibodies, and complement C8 alpha-gamma (C8α-γ) deficiency.
In so many words, stress hives are caused by excessive stress. When you’re stressed out, your immune system is thrown off a little bit. In an effort to try to “fix” the problem (stress), your immune system sends out histamine. It’s as if your body becomes allergic to stress.Since histamine can’t cure stress, it causes your body to develop hives instead.
Urticarial lesions itch, have a central white wheal that is elevated, and are surrounded by an erythematous halo. The lesions are typically rounded and circumscribed. Characteristically, hives should blanch with pressure; they generally resolve within 24 hours, leaving no residual change to the skin. The redness, which is augmented by local neural reflexes, is due to dilated blood vessels in superficial layers of the skin; the wheal is due to leakage of these vessels as fluid extravasates and compresses the vessels beneath it so that the central area appears clear.
In some patients, foods such as egg white, shellfish and strawberries seem to trigger direct histamine release from mast cells and episodes of urticaria are related to ingestion of these foods. Again, skin prick testing and SIgE tests to the foods are negative, as the reaction is not IgE-mediated.

Intense emotional responses can trigger a hives outbreak. For those with chronic hives, or hives that persist for more than six weeks at a time, stress and anger can heat up the body and cause it to release histamine.
If hives become a chronic or long-term problem, you should ask your physician for a referral to a specialist. An allergist can test you in order to determine, if possible, the cause of your allergic reaction. These allergy tests will cover foods, plants, chemicals, insects, and insect bites.

Heat-induced urticaria:This is a common form of chronic urticaria (5-7%). It appears as small wheals (1-2 in diameter), with large areas of flares around it. It frequently involves the skin of the neck and chest. It is associated with increased body temperature, e.g., after exercise, hot showers and emotional stimuli.
Protect yourself from pollen. There are some cases where environmental agents can cause hives. If you react to pollen, avoid being outside in the morning and in the evening when pollen levels are at their highest. Keep your windows closed during these times as well and avoid drying clothes outside. Change into “indoor clothes” as soon as possible and wash your “outdoor clothes” right away.
Allergic reactions to foods such as nuts, seafood (including fish), chocolate, berries and milk common causes of ordinary hives. Viral infections, insect bites and medications can also cause ordinary hives.
Urticaria is the medical name for hives. These are welts; pink swellings that come up on any part of the skin. They itch and each individual hive lasts a few hours before fading away, leaving no trace. New hives appear as old areas fade. They can be pea sized or join to cover broad areas of the body. While the itch can be intense, the skin is usually not scabbed or broken. In some people the hives burn or sting.
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.
Hives and stress are close related. The ideal stress hives cure would be to get rid of all the stress and tension in your body, but to be honest that´s impossible. Try at least to manage your stress levels and try and get rid of some tension. Try relaxation techniques such as yoga, meditation and self hypnosis, these methods can relieve your stress rash over time.

When an individual is stressed, his or her body releases hormones such as adrenaline and cortisol. The sudden release of those hormones creates a hormonal imbalance that can cause hives in sensitive individuals.
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.
Treatment depends on the extent of symptoms and organ involvement. When levels of complement are normal and there is no internal organ involvement or underlying disease, the symptoms may improve on their own or with minimal treatment. In this case, antihistamines or nonsteroidal drugs such as ibuprofen or naproxen may be helpful. For more severe cases, other drugs which affect the immune system may be needed, such as corticosteroids (prednisone, others), hydroxychloroquine, colchicine, dapsone; and chemotherapies like azathioprine or cyclophosphamide. Treatment may be intermittent, although it is not uncommon for patients to need treatment for several years.
When my son came in contact with caterpillars he would break out in giant hives all over his body. THANK GOD FOR THE SASAFRASS TREE!!! I would make him a cup of tea and within 30 minutes the hives disappeared completely when Benadryl never did. Can be bought at your local grocers.
In children, urticaria is more often acute than chronic. Acute urticaria is caused frequently by IgE-mediated allergic reactions to foods or by acute infections, usually viral respiratory tract infections. ‘Papular urticaria’ occurs more often in children than in adults, and is due usually to insect bites. There is an immediate IgE-mediated weal and flare reaction, but lesions can develop into intensely itchy, indurated papules which may take several weeks to resolve.
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.
Steroid-sparing options:  The older tricyclic antidepressant Doxepin (10 to 50mg daily) has histamine blocking properties and is useful as an adjunct especially if there is co-existent depression with the urticaria.  Leukotriene Receptor antagonists, Singulair or Montelukast (10mg at night) has been used with variable success, and is most effective when used in combination with non-sedating anti-histamines.  Montelukast is very useful in aspirin sensitive individuals (who are prone to urticaria, nasal polyps and asthma).

“Chronic idiopathic hives are itchy red welts that persist for at least six weeks and have no known cause,” says Miriam Anand, MD, an allergist with Allergy Associates and Asthma in Tempe, Arizona. The condition is marked by periods of exacerbation and remission, and for many who have it, the hives may persist for more than five years.

The most common foods that cause hives are nuts, chocolate, fish, tomatoes, eggs, fresh berries, soy, wheat, and milk. Fresh foods cause hives more often than cooked foods. Certain food additives and preservatives may also be to blame.
The physical urticarias in which some physical stimulus causes urticaria include immediate pressure urticaria, delayed pressure urticaria, cold urticaria, and cholinergic urticaria. [17, 18] For some urticarias, especially chronic urticarias, no cause can be found, despite exhaustive efforts—the so-called idiopathic urticarias, although most of these are chronic autoimmune urticaria as defined by a positive autologous serum skin test (ASST). [19] This test is not specific for autoantibodies against a specific antigen or diagnostic of a specific disease state. [20] To date, no reliable test exists to identify with certainty if chronic urticaria is autoimmune or nonautoimmune in the specific patient. [21, 22]
Swelling of deeper layers of the skin, angioedema, commonly accompanies urticaria (click for picture). This swelling often results from the same inflammatory processes that cause hives. The redness that is seen surrounding superficial lesions is not observed, though the swelling is readily appreciated. Angioedema generally occurs on the extremities and digits as well as areas of the head, neck, face, and in men, genitalia. It is often described as being painful or burning.
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 that causes acute hives is not the same as what causes chronic hives.
Clinical Context:  Hydroxychloroquine is the preferred antimalarial agent because of its low toxicity and high effectiveness profile. It is usually well tolerated if carefully monitored by the prescribing physician. Therapy is required for 4-8 weeks before evaluating effectiveness.
As far as the physical symptoms, you’ll see red bumps and swelling of the skin. They can develop anywhere on your body and be any size. Some people get breakouts as small as a penny, others get stress hives the size of a dinner plate or larger. Urticaria also has a tendency to spread around your body when you leave it untreated which is why you shouldn’t ignore it.
Physical urticaria (for example, heat hives) is a type of chronic urticaria produced by physical stimuli. Common environmental provocations such as sunlight, water, cold, heat, exercise, pressure occasionally induce hives. Dermographism, which literally means “skin writing,” is a common cause of physical urticaria. This is an exaggerated form of what happens to anyone when their skin is scratched or rubbed; a red welt appears at the site of the scratch. In dermographism, raised, itchy red welts with adjacent flares appear wherever the skin is scratched or where belts and other articles of clothing rub against the skin, causing mast cells to leak histamine.
Urticaria affects almost 20 percent of the population but the majority of the time, the cause is unknown (idiopathic). Even so, it is a good idea to try to find the trigger so you can possibly avoid it in the future.
Hives can be caused from allergens as well as physical and environmental factors such as stress, heat, sunlight or water. Untreated, the symptoms can last from a couple hours up to six weeks. As we’ll see throughout this article, many skin disorders share these causes and triggers, so close attention to detail is key when figuring out the mystery of your skin disorder.
If you have a severe episode of hives then you may be referred to a specialist. Skin specialists (called dermatologists) or allergy specialists (called immunologists) may be able to help. In particular, if angio-oedema or anaphylaxis occurred at the same time, you would be referred or admitted to hospital. This is to reverse the reaction quickly. It is also to confirm the diagnosis and, where possible, to identify a cause. For example, if a nut allergy is suspected to have caused a severe episode then this can confirmed by tests. You may then be given advice on how to avoid the cause and on what to do if it should occur again.
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]
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.
On 2 July 2010, the band released an EP titled Tarred and Feathered, which covered “Civilization’s Dying” by Zero Boys, “Nasty Secretary” by Joy Rider & Avis Davis and “Early Morning Wake Up Call” by Flash and the Pan.[12][13] “Nasty Secretary” is also a song on the US release of the Gran Turismo 5 soundtrack. On 9 January 2011, Nicholaus Arson wrote another short diary entry on the band’s website saying that they had recorded some new songs before Christmas, and were planning to continue recording throughout January.[14]
Cholinergic urticaria (CU) is one of the physical urticaria which is provoked during sweating events such as exercise, bathing, staying in a heated environment, or emotional stress. The hives produced are typically smaller than classic hives and are generally shorter-lasting.[13][14]
This is termed scombroid food poisoning. Ingestion of free histamine released by bacterial decay in fish flesh may result in a rapid-onset, allergic-type symptom complex which includes hives. However, the hives produced by scombroid is reported not to include wheals.[21]

Angioedema is similar to hives, but the swelling occurs beneath the skin instead of on the surface. Angioedema is characterized by deep swelling around the eyes and lips and sometimes of the genitals, hands, and feet. It generally lasts longer than hives, but the swelling usually goes away in less than 24 hours.
Acute urticaria is nearly always due to some defined exposure to a drug or physical stimulus or an acute infectious illness. However, the trigger is not always clear from the history, particularly because allergy may develop without warning to a previously tolerated substance.
A single hive generally fades in about 24 hours. But new hives may form as old hives disappear. If you have multiple hives, you may experience these symptoms for about 6 weeks. This is considered a bout of acute hives.
