“chronic hives +hives on neck”

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.
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.

Urticaria is a common condition – it is estimated that lifetime incidence of urticaria is approximately 15%, with females being affected more often than males. Both children and adults may develop urticaria, with the peak age of onset in adults being between 20 and 40 years. Urticaria is defined as ‘acute’ if it lasts for less than 6 weeks and ‘chronic’ if it lasts for more than 6 weeks. ‘Episodic’ urticaria, which occurs intermittently, but recurrently over months or years, is also recognized. Most urticarial reactions are acute and self-limiting; however, patients referred to allergy clinics usually have chronic urticaria or episodic urticaria. Histology shows oedema of the upper dermis, dilatation of blood vessels and lymphatics and a cellular infiltrate in the dermis. The nature of this cell infiltrate varies depending on the type of urticaria and the duration of the weal.
In patients with very severe acute urticaria, associated possibly with angioedema or systemic symptoms, a short course of oral steroids is indicated. Dose and duration of the treatment is determined by the patient’s weight and clinical response. Prolonged courses of oral steroids for chronic urticaria should be avoided whenever possible, and if long-term steroid treatment is considered necessary, the patient should be followed-up regularly and prescribed prophylactic treatment against steroid-induced osteoporosis at an early stage [56]. Oral steroids may be needed for urticarial vasculitis (see below) or severe delayed pressure urticaria.
“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.
Insect bites and exposure to pollen can make you break out in hives, but you probably already knew that. What you may not have realized is that direct sunlight, cold temperatures, or strong winds can also bring on hives. And no, this doesn’t mean you’re allergic to the elements. “It’s really more that your skin is very sensitive,” says Marilyn Li, MD, a Los Angeles-based allergist and immunologist.
Chronic hives can be difficult to treat and lead to significant disability. Unlike the acute form, 50–80% of people with chronic hives have no identifiable triggers. Fortunately, 50% of people with chronic hives will experience remission within 1 year.[36] Overall, treatment is geared towards symptomatic management. Individuals with chronic hives may need other medications in addition to antihistamines to control symptoms. Patients who experience hives with angioedema require emergency treatment as this is a life-threatening children, an objective trial of a low E numbers diet may be helpful, especially if the clinical history suggests that episodes of urticaria may be related to ingestion of foods which are high in E numbers.

Abdominal examination should note any masses, hepatomegaly, splenomegaly, or tenderness. Neurologic examination should note any tremor or hyperreflexia or hyporeflexia. Musculoskeletal examination should note the presence of any inflamed or deformed joints.
If a non-drowsy antihistamine doesn’t work, the doctor may suggest a stronger antihistamine or another medicine or a combination of medicines. In rare cases, a doctor may prescribe a steroid pill or liquid to treat chronic hives. Usually this is done for just a short period (5 days to 2 weeks) to prevent harmful steroid side effects.
Health advice on severe hives: I have had severe hives for 1 week. Treating with 300mg of benadryl ea day, Doxypin 10 mg at bedtime and prednisone 40 mg. I am very concerned about being on Prednisone especially since it is not doing any good. Does pred
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.

Urticaria results from the release of histamine, bradykinin, leukotriene C4, prostaglandin D2, and other vasoactive substances from mast cells and basophils in the dermis. These substances cause extravasation of fluid into the dermis, leading to the urticarial lesion. The intense pruritus of urticaria is a result of histamine released into the dermis. Histamine is the ligand for two membrane-bound receptors, the H1 and H2 receptors, which are present on many cell types. The activation of the H1 histamine receptors on endothelial and smooth muscle cells leads to increased capillary permeability. The activation of the H2 histamine receptors leads to arteriolar and venule vasodilation. [14, 15]
There are many causes of urticaria; allergic and non-allergic. In about 90% of people with chronic urticaria, no cause is found even after exhaustive investigations. In acute urticaria the chances of determining the cause are higher. For example, many cases of acute urticaria in children may be associated with a viral, bacterial or parasitic infection. Stress can certainly make established symptoms worse, but is very rarely the direct cause of urticaria.
Practice positive affirmations. Positive affirmations are phrases you say to yourself to help reduce your stress and bring up your mood. When saying these, use the present tense and repeat as often as you can. Examples of positive affirmations are:
First off, if you think you know what caused your hives, then avoid further contact or consumption with whatever it is. If you suspect that your hives are being caused by a particular food you’re eating or a certain pet you currently have in your home, then it is a good idea to get some allergy testing done. Allergy testing can reveal your hive triggers, which you can then avoid (as much as possible) and you can greatly prevent the likelihood of another undesirable hives rash. (15) Keeping a food diary can also help a hive sufferer to pinpoint any food allergies.

Make a homemade oatmeal bath. Oatmeal is one of the best natural ways to treat the itchy, irritated skin associated with hives. Get a cup of plain, all natural rolled oats and place them in a food processor or coffee grinder. Pulse until there the oatmeal becomes a thick powder. Once it is ground into the fine substance, place one to two cups of rolled oats in a warm or cool bath, which will make the water a white colored, thick consistency. Get into the bath and soak for as long as you want. Repeat as often as needed.
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.
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.
For those with chronic hives from heat-induced or illness-induced activities, Dr. Li suggests visiting a doctor to pinpoint the symptoms and receive an antihistamine prescription. “The solutions are individualized and many times may involve just taking a little more medication,” she says.
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.
Asthma drugs with antihistamines. Medications that interfere with the action of leukotriene modifiers may be helpful when used with antihistamines. Examples are montelukast (Singulair) and zafirlukast (Accolate).

Chronic cases are much more likely to be related to autoimmune causes than allergies. In the autoimmune form of urticaria and angioedema, a person makes antibodies against a component of their mast cells, triggering the release of histamine and causing symptoms.
Systemic cold urticaria yields severe generalized hive formation resulting from systemic cold challenge occurring over covered or uncovered parts of the body. Symptoms are unrelated to exercise or other activities, and the ice-cube test is negative.

NUV is diagnosed where a patient has the main symptoms of Urticarial Vasculitis combined with normal levels of C1q complements. NUV is generally the least severe form of Urticarial Vasculitis. It is less likely to be associated with any other symptoms.
If your child has chronic hives, the doctor may ask you to keep a daily record of activities, such as what your child eats, drinks, and where the hives tend to show up on the body. Diagnostic tests — such as blood tests, allergy tests, and tests to rule out underlying conditions such as thyroid disease or hepatitis — might be done to find the exact cause of the hives.

Antihistamines remain the mainstay of treatment. They must be taken on a regular basis, rather than as needed. Newer oral antihistamines often are preferred because of once-daily dosing and because some are less sedating. Appropriate choices include
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.
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]
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).
Do you know the causes and symptoms of hives? It’s helpful to know both so that you can avoid hives, or recognize them if they do appear on yourself or a loved one. Conventional hives treatment comes with the possibility of unwanted side effects. Why not choose a natural hives treatment? Nobody likes walking around with bumps or welts on their skin. Let’s talk about how to avoid hives, how to identify hives and how to treat hives naturally.

“chronic urticaria treatment +yurtici kargo takibi”

Urticaria predominantly affects adult females and up to 20% of the population sometime in their life.  It presents as a diffusely raised itchy wheal and flare reaction which migrates over the skin surface. All forms of Urticaria may occur in association with deeper skin swelling or angioedema and equally, angioedema may occur in isolation with no apparent urticaria (when Hereditary Angioedema (HAE) due to a deficiency of the C1 Esterase inhibitor enzyme should be suspected).
Lesions of urticarial vasculitis initially appear as erythematous wheals (see image below). As the lesions progress, purpura may develop. Often, the urticarial vasculitis lesions resolve with postinflammatory pigmentation. Annular or targetoid lesions may be observed.
As noted above, many cases of ordinary hives are “idiopathic,” meaning no cause is known. Others may be triggered by viral infections. A few may be caused by medications, usually when they have been taken for the first time a few weeks before. (It is less likely for drugs taken continuously for long periods to cause hives but certainly not impossible.) When a medication is implicated as a cause of hives, the drug must be stopped, since testing is rarely available to confirm the cause. In most cases, drug-induced hives will go away in a few days. If a drug is stopped and the hives do not go away, this is a strong indication that the medication was not the cause of the hives.
TREATMENT FOR CHRONIC URTICARIA: HAVE CHRONIC URTICARIA FOR 11 YEARS,I HAVE BEEN TO SEE EVERYONE AND NOTHING SEEMS TO WORK .THE ONLY TIME I WENT IS WHEN I WAS IN INTENSIVE CARE BUT I CANT SLEEP FOREVER! ANY SUGGESTIONS, YOURS ITCHINGLY LEE GILLOTT
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.
Where possible, identify and treat the cause. Nonspecific aggravating factors should be minimised, such as overheating, stress, alcohol, caffeine and medication likely to cause urticaria (eg, non-steroidal anti-inflammatory drugs (NSAIDs) and angiotensin-converting enzyme (ACE) inhibitors). Topical anti-pruritic agents such as calamine lotion or topical menthol 1% in aqueous cream may help ease symptoms.
Examination of the head should note any swelling of the face, lips, or tongue; scleral icterus; malar rash; tender and enlarged thyroid; lymphadenopathy; or dry eyes and dry mouth. The oropharynx should be inspected and the sinuses should be palpated and transilluminated for signs of occult infection (eg, sinus infection, tooth abscess).
There are other medications that may be added to the antihistamines, but these non-standard therapies are not always effective. However, if the hives are not responding, they are worth a try. Examples are anti-acid pills (cimetidine, ranitidine), dapsone and sulfasalazine (anti-inflammatory antibiotics), nifedipine (a blood pressure medicine), Accolate (an asthma drug), colchicine (a drug for gout), and several others.
Hives are an unpleasant inflammatory skin condition that 20 percent of the population will experience at some point in time. Thankfully, hives typically are  not serious. With some simple natural remedies, you can calm a hives outbreak on yourself or your child quite quickly. Inexpensive, common household items like oatmeal, witch hazel and baking soda are really effective at calming the itching and redness that usually accompany hives. If your child experiences hives, you should make sure you aren’t using any harsh body care products on his or her skin. You should also avoid hot baths and tight-fitting clothes. I hope that you won’t experience hives anytime soon, but if you do, a natural hives treatment will really come in handy.

The first symptom of urticarial vasculitis is an urticarial eruption that is often painful or has a burning sensation. In some cases there may be pruritus. Lesions are red patches or plaques that may have a white centre, and petechiae may appear. They usually last for more than 24 hours in a fixed location, after which they will slowly resolve spontaneously. Ecchymoses or hyperpigmentation may occur in the healing process.

The Hives live show has been highly rated, Spin magazine rating them 8th best in rock music.[26] Pelle is known for his “colourful idiocy” on stage.[27] When asked about their efforts to connect with the audience, Chris Dangerous replied that “there are so many bands out there that don’t say a word to the crowd. I don’t get it. They don’t even look at the audience and that’s ridiculous”.[28] The Hives always dressed in black-and-white uniforms because “it makes [them] look like [they] belong together”.[29]
The most common form of mastocytosis, maculopapular cutaneous mastocytosis is also urticaria pigmentosa. Itchy brown patches or freckles on the skin are due to abnormal collections of mast cells.
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.
Management of urticaria is focused on treating the symptoms and typically is not altered by underlying etiology. The mainstay is avoidance of further exposure to the antigen causing urticaria. Pharmacologic treatment options include the following:

I have had urticaria for 7 years, and in that time I’ve made some discoveries. First, upon the first sensations of an itch, DO NOT SCRATCH IT; slap it instead. If that doesn’t work, I’ve found that a bath in the hottest water possible really helps to releive my discomfort/itch, then put on a long-sleeved cotton shirt that is relatively form-fitting (but not constrictive) and cotton yoga pants. I’ve noticed a link between my consumption of peanuts/peanut butter, coffee, and, yes, even chocolate to uriticaria outbreaks. Since I’ve eliminated peanuts/peanut butter from my diet entirely, I almost never get outbreaks (except the rare days that I have a cup of coffee as a special treat–then I know what I’m in for). Try experimenting with your diet, but I know the above mentioned foods are known to be common allergy-producing foods, so this could be a good starting (and perhaps ending) point… Good luck!
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.

As with adults, any potential triggering factors should be identified and, if possible, avoided. Non-sedating H1 anti-histamines are the first-line medical treatment. All these drugs are licensed for children over 12. Age restrictions and dosage vary for the different drugs in younger children. Cetirizine, desloratidine, levocetirizine and loratidine are all available as syrups, with desloratidine being licensed for the youngest age group (1–5 years). In children under 1 year, only the sedating H1 anti-histamines chlorphenamine and hydroxyzine are licensed. High-dose treatment, or a combination of two different non-sedating H1 anti-histamines, or a combination of a non-sedating H1 anti-histamine in the morning, with a sedating H1 anti-histamine at night may be needed. If symptoms are still not well controlled, an H2 receptor antagonist and/or a LTRA may be tried. Montelukast is licensed for prophylaxis of asthma in children from 6 months of age and is available as granules and as a chewable tablet for younger children as well as in a standard tablet format. Zafirlukast is licensed for prophylaxis of asthma in children from 12 years of age and is available only in a standard tablet format. Finally, if high-dose H1 anti-histamines, H2 receptor antagonists and LTRA are ineffective, oral steroids may be needed; however, even oral steroids may be ineffective if the child has severe physical urticaria. Referral to a specialist centre is suggested if the child has very severe symptoms.
An easy natural cure for hives is to soak a ball of cotton wool in milk of magnesia and apply the lotion all over the rash. Milk of magnesia has alkaline properties that help in soothing the skin and reducing the pain as well. In place of milk of magnesia, you can apply vitamin E oil for the same results. Repeat this process at least twice to three times a day.
Many antihistamines are available without prescription, such as diphenhydramine (Benadryl), taken in doses of 25 milligrams, and chlorpheniramine (Chlor-Trimeton), taken in a dose of 4 milligrams. These can be taken up to three times a day, but because these medications can cause drowsiness, they are often taken at bedtime. Those who take them should be especially careful and be sure they are fully alert before driving or participating in other activities requiring mental concentration.
Try vinegar. There are many healing nutrients in vinegar. Pick any kind of vinegar. Pour 1 tsp of vinegar into 1 tbsp of water and stir. Using a cotton ball or napkin, apply the mixture to your hives. This will help soothe the itching.[11]

“treatment for urticarial vasculitis -is urticaria contagious”

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.
Many medications can cause hives, but only about 10% of hives are caused by medications. Hives will most often occur in the first 36 hours after starting the medication, but hives can occur even after taking a medicine for a long time. You can see that antibiotics are a common culprit.

Systemic cold urticaria yields severe generalized hive formation resulting from systemic cold challenge occurring over covered or uncovered parts of the body. Symptoms are unrelated to exercise or other activities, and the ice-cube test is negative.
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.

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.
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 cholinergic urticaria is quite variable, with most patients experiencing slow resolution over several years.

In most cases of chronic urticaria and angioedema, symptoms last less than a few months to a few years. Some people may experience symptoms for many years, and those who do should be seen by an allergist for an appropriate diagnosis and treatment plan. 
Another common form of physically induced hives is called cholinergic urticaria. This produces hundreds of small, itchy bumps. These occur within 15 minutes of exercise or physical exertion and are usually gone before a doctor can examine them. This form of hives happens more often in young people.

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.
Antihistamines that require a prescription include cyproheptadine (Periactin), which tends to cause drowsiness. A prescription antihistamine that causes little sedation is levocetirizine (Xyzal). Sometimes physicians combine these with other types of antihistamines called H2 blockers, such as ranitidine (Zantac) and cimetidine (Tagamet). This antihistamine list is not exhaustive. Physicians individualize treatment plans to suit specific patients and modify them depending on the clinical response.
In chronic cases, a physician may check various blood and urine tests, and other procedures such as X-rays to look for other causes. If a physical urticaria is suspected, special tests to mimic the physical stimulus may be performed, such as placing an ice cube on the skin to cause a hive to form in people with cold urticaria.

“remedios para la urticaria multivariable function”

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.
The cause of Urticarial Vasculitis is not known in 50 per cent of cases. However it can be associated with or triggered by autoimmune/connective tissue diseases like Systemic Lupus Erythematosus (SLE or simply Lupus) Rheumatoid Arthritis, or occur in the context of a systemic vasculitis syndrome, such as Churg Strauss syndrome (Eosinophillic Granulomatosis with Polyangiitis); infections or viruses such as hepatitis; a reaction to certain drugs such as ACE inhibitors; certain types of diuretics; penicillin and Non-Steroidal Anti-Inflammatory Drugs (NSAIDs); cancer; and Glandular problems, such as Graves’ Disease (overactive thyroid).

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.
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.
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)
Once a diagnosis of urticarial vasculitis is made, follow-up care depends on the patient’s complement levels. If complement level findings are normal, follow patients for symptoms and response to treatment. If complement level findings are low, follow patients for attendant complications related to the cause of their hypocomplementemia (see History).
Acute hives can be triggered by a number of different factors. Common causes include respiratory infections (particularly in young children), contact with animals or plants, allergic reactions to foods or medication (particularly pain relievers and antibiotics), and sometimes, insect stings, heat or cold, stress, food additives or preservatives. 
If you have persistent urticaria, you may be referred to a skin specialist (dermatologist). Treatment usually involves medication to relieve the symptoms, while identifying and avoiding potential triggers.
Cholinergic urticaria is a common physical urticaria that is caused by sweating. It is sometimes referred to as heat bumps, as the rash appears as very small (1-4mm) weals surrounded by bright red flares.
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.
Unusual, recurrent, or persistent cases warrant further evaluation. Referral for allergy skin testing should be done, and routine laboratory tests should consist of CBC, blood chemistries, liver function tests, thyroid-stimulating hormone (TSH). Further testing should be guided by symptoms and signs (eg, of autoimmune disorders) and any abnormalities on the screening tests (eg, hepatitis serologies and ultrasonography for abnormal liver function tests; ova and parasites for eosinophilia; cryoglobulin titer for elevated liver function tests or elevated creatinine; thyroid autoantibodies for abnormal TSH).
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.
Acute and chronic urticaria can result in severely impaired quality of life from pruritus and associated sleeplessness, as well as anxiety and depression. The depression can be severe enough to lead to suicide in rare cases. Additionally, many of the diseases associated with chronic urticaria may cause significant morbidity and mortality.
Papular urticaria is rare in the first year of life. It is most common in children between the ages of 2 and 7 years, but may occur in adults. The incidence decreases with age, presumably because one gets less sensitive with each bite. Papular urticaria is frequently seasonal, especially in temperate climates where they are worst in the summer. However, it can occur throughout the year.
Disorders such as cold urticaria, cholinergic (generalised heat) urticaria, and dermatographism can be treated with antihistamines such as fexofenadine, cetirizine or loratidine. If so severe that responsiveness to these is insufficient, higher than normal doses can be used (example fexofenadine 180 mg twice daily; cetirizine 10 mg up to 4 times a day). The next step is higher concentrations of antihistamines such as hydroxyzine or diphenydramine at 25-50 mg four times a day. In some instances, when severe, a particular drug is tried, eg, cyproheptadine 4-8 mg, 3-4 times a day, to treat cold urticaria or hydroxyzine 50 mg four times a day for cholinergic urticaria. Solar urticaria (light-induced urticaria) is treated with antihistamines and sun-screens, if sensitivity is to u.v. wavelengths. Sensitivity to visible light wavelengths is particularly difficult since symptoms can occur indoors as well as outdoors. Delayed pressure urticaria is an exception where symptoms more closely resemble CSU (with which it is commonly associated) and responds poorly to antihistamines.  It can be treated with cyclosporine or, perhaps, omalizumab.  It does respond to corticosteroid.

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 rare painful non-migratory wealing reaction which persist for more than 24 hours and is often associated with fever, bruising and joint pain.  The associated with an underlying auto-immune diseases such as Serum Sickness, Systemic Lupus and Sjogren’s Syndrome should not be overlooked.  Urticaria Pigmentosa is a diffuse dark freckle-like rash that weals on rubbing the skin (Dariers sign) and is due to excess mast cells in the skin (Cutaneous Mastocytosis).  Children frequently develop discrete linear or grouped itchy Papular Urticaria from insect bite sensitivities.
“I’ve seen kids break out in hives from having a temper tantrum,” Dr. Li says. “Certainly, stress that’s anxiety-related can cause more itching in patients who have hives and they start to have more hives as a result of itching and scratching the existing ones.”
Applying something cool to your skin can help relieve any irritation. To do this, grab a bag of frozen veggies or wrap a handful of ice in a towel and apply to the affected area for up to 10 minutes. Repeat as needed throughout the day.
Acute urticaria is defined as the presence of evanescent wheals which completely resolve within six weeks.[31] Acute urticaria becomes evident a few minutes after the person has been exposed to an allergen. The outbreak may last several weeks, but usually the hives are gone in six weeks. Typically, the hives are a reaction to food, but in about half the cases, the trigger is unknown. Common foods may be the cause, as well as bee or wasp stings, or skin contact with certain fragrances. Acute viral infection is another common cause of acute urticaria (viral exanthem). Less common causes of hives include friction, pressure, temperature extremes, exercise, and sunlight.
Up to 20% of people will develop hives at some time during their life.  In most cases, hives are not due to allergy. Underneath the lining of the skin and other body organs (including the stomach, lungs, nose and eyes) are mast cells. Mast cells contain chemicals including histamine. When these are released into the skin they irritate nerve endings to cause local itch and irritation and make local blood vessels expand and leak fluid, triggering redness and swelling.
In his book Urticaria No More, Yassin Madwin stresses that hives cannot be caused by stress, confirming this theory. He shows how hives occur when there is a spike in certain hormones; these hormones need serotonin to work properly (serotonin, AKA the happiness hormone). The more you’re stressed, the more your cortisol rises and your serotonin drops. When this happens, a set of pro-inflammatory agents (basophils) are released into the blood stream, which requires histamine intervention.
Omalizumab, an anti-IgE antibody[9]. It is effective in 80% but requires monthly injections and relapse is common when it is stopped. The National Institute for Health and Care Excellence (NICE) recommends omalizumab as an add-on treatment for refractory severe chronic spontaneous urticaria[10].
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.
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.
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.
Try coleus forskohlii. Coleus forskohlii is a plant native to Southeast Asia that is used in Ayurvedic medicine. Studies have shown that it reduces the histamine and leukotriene release from mast cells when you get hives.[23]

Starting with 10 minutes of exercise a day can lower your overall feelings of stress. The hormones produced by your exercise session can help you better deal with stressful situations, even long after you have finished exercising.
Your dermatologist may call this type of hives fixed, which means not moving. Fixed hives may happen when a person takes a certain medicine (fixed drug eruption) or gets too much sunlight (fixed solar urticaria).
The intense itching can become unbearable to the point where the individual may inadvertently cause damage to the skin by scratching at the affected areas. The condition can be disturbing to parents who have never experienced it themselves, but observe it in their children. Although you may find yourself exasperated as your child continues to scratch at the skin, despite your warnings against doing so, you need to keep your calm. The intense itching can be unbearable, and even adults find it near impossible to restrain themselves. Instead of admonishing your child, , make sure that you take steps to minimize the discomfort and try to distract a child with hives so that they do not scratch the rash. In severe cases, the individual may also have a fever and may suffer from digestive distress. In most cases, the rash subsides for a couple of hours or even days before it returns. Other severe urticaria symptoms include periodic flushing, headaches, dizziness, respiratory problems, fluid retention, tongue or facial swelling and hypotension. Medical attention is essential, as if neglected, severe cases of utricaria can even cause asphyxiation, resulting in death. There are several ongoing research programs to understand the exact causes of this condition in order to increase effectiveness of existing treatment methods.
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.
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.
Make a homemade oatmeal bath. Oatmeal is one of the best natural ways to treat the itchy, irritated skin associated with hives. Get a cup of plain, all natural rolled oats and place them in a food processor or coffee grinder. Pulse until there the oatmeal becomes a thick powder. Once it is ground into the fine substance, place one to two cups of rolled oats in a warm or cool bath, which will make the water a white colored, thick consistency. Get into the bath and soak for as long as you want. Repeat as often as needed.
The band also won five prestigious Swedish Grammis for Tyrannosaurus Hives at the 23rd annual Swedish Grammis Awards, presented on 7 February 2005 for “Artist of the Year”; “Rock Group of the Year”; “Album of the Year”; “Producer of the Year” (with collaborator, Pelle Gunnerfeldt); and “Walk Idiot Walk” took home the MTV “Best Music Video” prize.[7][8]
Clinical Context:  Dapsone is the preferred sulfone. Other sulfones must be metabolized to dapsone for their effect. The mechanism of action is similar to that of sulfonamides in which competitive antagonists of PABA prevent the formation of folic acid, inhibiting bacterial growth.
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.
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.
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]

When you’re stressed, it isn’t uncommon to experience a flare-up related to an existing skin condition. This is because your body releases extra chemicals, like neuropeptides and neurotransmitters, when you’re stressed. These chemicals can change how your body responds to various functions. This change in response can cause inflammation, sensitivity, and other discomfort to the skin.
“This subset — about 30 percent of patients who have been diagnosed with idiopathic urticaria — is the group in which we most often look to psychological factors for an explanation,” she says. “Many dermatologists will agree that it is not uncommon to see chronic idiopathic urticaria arising after a major life stressor, or for patients who are most impaired by urticaria to be those with more limited stress management skills.”
If you have chronic stress or are experiencing symptoms that interfere with your life, or are causing frequent outbreaks of hives, it might be beneficial to talk to your doctor about medical treatments for stress. There are also a number of lifestyle changes you can make to help reduce overall stress.
Urticarial weals can be a few millimetres or several centimetres in diameter, coloured white or red, with or without a red flare. Each weal may last a few minutes or several hours, and may change shape. Weals may be round, or form rings, a map-like pattern or giant patches.
Hives frequently occur following an infection or as a result of an allergic reaction such as to medication, insect bites, or food.[2] Psychological stress, cold temperature, or vibration may also be a trigger.[1][2] In half of cases the cause remains unknown.[2] Risk factors include having conditions such as hay fever or asthma.[3] Diagnosis is typically based on the appearance. Patch testing may be useful to determine the allergy.[2]

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.
Other options for refractory symptoms of chronic hives include anti-inflammatory medications, omalizumab, and immunosuppressants. Potential anti-inflammatory agents include dapsone, sulfasalazine, and hydroxychloroquine. Dapsone is a sulfone antimicrobial agent and is thought to suppress prostaglandin and leukotriene activity. It is helpful in therapy-refractory cases[44] and is contraindicated in patients with G6PD deficiency. Sulfasalazine, a 5-ASA derivative, is thought to alter adenosine release and inhibit IgE mediated mast cell degranulation, Sulfasalazine is a good option for people with anemia who cannot take dapsone. Hydroxychloroquine is an antimalarial agent that suppresses T lymphocytes. It has a low cost however it takes longer than dapsone or sulfasalazine to work.
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.

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 you’ll be able to get rid of them in no time.

“chronic spontaneous urticaria autoimmune and hives”

There are two types of hives – short-lived (acute) and long-term (chronic). Neither is typically life-threatening, though any swelling in the throat or any other symptom that restricts breathing requires immediate emergency care.
Urticarial weals can be a few millimetres or several centimetres in diameter, coloured white or red, with or without a red flare. Each weal may last a few minutes or several hours, and may change shape. Weals may be round, or form rings, a map-like pattern or giant patches.

This type of urticaria is also termed rare, and occurs upon contact with water. The response is not temperature-dependent and the skin appears similar to cholinergic form of the disease. The appearance of hives is within one to 15 minutes of contact with the water, and can last from 10 minutes to two hours. This kind of hives do not seem to be stimulated by histamine discharge like the other physical hives. Most researchers believe this condition is actually skin sensitivity to additives in the water, such as chlorine. Water urticaria is diagnosed by dabbing tap water and distilled water to the skin and observing the gradual response. Aquagenic urticaria is treated with capsaicin (Zostrix) administered to the chafed skin. This is the same treatment used for shingles. Antihistamines are of questionable benefit in this instance, since histamine is not the causative factor.[citation needed]
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.
Urticaria (hives) is a vascular reaction of the skin marked by the transient appearance of smooth, slightly elevated papules or plaques (wheals) that are erythematous and that are often attended by severe pruritus. Individual lesions resolve without scarring in several hours. Most cases of urticaria are self-limited and of short duration; the eruption rarely lasts more than several days, it but may be recurrent over weeks. Chronic urticaria is defined as urticaria with recurrent episodes lasting longer than 6 weeks).
The attack begins with red, raised, spongy welts on the skin that develop on a certain part of the body. These welts itchy and may increase in size over time. Sometimes they even join together to form a large raised rash
Hives can be triggered by some food additives, including artificial colors, flavoring agents, and preservatives, according to research published in June 2013 in the Indian Journal of Dermatology. However, food intolerances that trigger hives can’t be tested as easily as typical food allergies, since their underlying mechanism is different. If you suspect that your diet may be a trigger for your hives, your doctor may prescribe an elimination diet, which, over a period of several weeks, will test for a food intolerance.

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.
The majority of stinging insects in the United States are from bees, yellow jackets, hornets, wasps, and fire ants. Severity of reactions to stings varies greatly. Avoidance and prompt treatment are essential. In selected cases, allergy injection therapy is highly effective.

Non-sedating H1 antihistamines are the mainstay of treatment. Cetirizine, loratadine and fexofenadine are usual choices. Studies comparing antihistamines are limited and so far no single antihistamine has shown itself to be superior for chronic spontaneous urticaria[6]. Once symptom control has been achieved, the antihistamine should be continued for 3-6 months.
Understanding the mechanisms of allergy is recent — just over the past 35 to 40 years, says Marshall, who is director of the division of clinical immunology and allergy at the University of Mississippi Medical Center. While allergic diseases have both genetic and environmental components there’s still so much about allergy we don’t know.
San Francisco — Although the expression “I was so stressed I broke out in hives” is quite common, it can be a challenge for dermatologists to identify the psychosocial precipitants of chronic urticaria, according to Josie Howard, M.D., a psychiatrist in private practice, and clinical instructor departments of psychiatry and dermatology, University of California, San Francisco. But that is beginning to change, she says.
Hives, also called urticaria, are itchy, red bumps on the skin. They typically appear as an allergic reaction to food or medication, but can also be caused from emotional stress and environmental factors. Treatment for hives includes antihistamine medication, topical lotion and lifestyle change. Roughly 15 to 20 percent of all adults will be affected by hives during their lifetime, according to healthy-skin-guide.com.
An allergy refers to 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.
Rubbing or scratching (simple dermographism). This is the most frequent cause of physical urticaria. Symptoms appear within a few minutes in the place that was rubbed or scratched and typically last less than an hour.

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
An unusual, but well-recognized non-IgE-mediated, food-related cause of urticaria is histamine poisoning, which occurs if food containing a very high content of histamine is eaten. The best-known example is ‘scombroid poisoning’ which is due to ingestion of scombroid fish (spiny-finned fish of the mackerel genus), such as tuna, mackerel and swordfish, which has not been stored properly and in which bacteria have decarboxylated histidine to produce histamine. (Ingestion of spoiled non-scombroid fish including herring, sardines and anchovies may also cause histamine poisoning.) Symptoms usually begin within 1 h of ingestion of the fish and patients develop urticaria and gastrointestinal symptoms. In severe cases there may be bronchospasm and hypotension [12,13].
Chronic spontaneous urticaria (click for picture) is characterized by a non-necrotizing perivascular mononuclear-cell infiltrate (CD4 positive T lymphocytes and monocytes) with variable accumulation of eosinophils, neutrophils, and mast cells (click for picture). Patients with vasculitis and urticaria appear to be a separate sub-population in whom the cause and pathogenesis of hive formation probably involves immune complexes, complement activation, anaphylatoxin formation, histamine release, and neutrophil accumulation, activation, and degranulation.
In this rare form of physical urticaria, hives occur after exposure to the sun or to certain artificial light sources. It is believed that the condition is an allergic reaction to an antigen formed by the interaction of light waves on the skin. Antihistamines are helpful to relieve the itch.
