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).
I bought some Sovereign Silver from a health shop in America. It is an immune builder. My Urticaria was gone I swear within THREE days. You have to buy it online here but if you haven’t tried it then please do as it may work for you as it has for me. My rash was horrendous and covered every bit of my body.
Urticaria is a skin condition commonly known as hives. It produces an itchy rash that tends to come and go and can last for a variable period of time. The condition can be acute (lasting less than 6 weeks) or chronic (lasting longer than 6 weeks). Most cases of urticaria have no known cause.
This means there is no explanation for what’s causing it. This can be difficult for some people to accept when they receive the CIU diagnosis from their doctor. Because these chronic hives symptoms come and go without a known cause, many who have been diagnosed with CIU continue to look for possible triggers for their disease. This can turn into a cycle of elimination diets, changing of detergents and other changes in addition to tests for allergies – none of which prove to be the cause of these patients’ hives.
1. Mint juice in small quantity of water without any additives to be taken twice a day. In winter, mint leaves can be boiled, water thereafter can be drunk. 2. 5 Gms of Soda Bicarbonate (cooking soda) dissolved in ordinary water at room temperature, can be applied to affected areas.
When you have an allergic reaction to a substance, your body releases histamine and other chemicals into the blood. This causes itching, swelling, and other symptoms. Hives are a common reaction. People with other allergies, such as hay fever, often get hives.
The immediate symptoms of this type are treated with antihistamines, epinephrine and airway support. Taking antihistamines prior to exercise may be effective. Ketotifen is acknowledged to stabilise mast cells and prevent histamine release, and has been effective in treating this hives disorder. Avoiding exercise or foods that cause the mentioned symptoms is very important. In particular circumstances, tolerance can be brought on by regular exercise, but this must be under medical supervision.[citation needed]
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!
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.

While your morning jog or post-work weightlifting regimen can boost endorphins, your daily dose of exercise could also be causing you to break out in hives. Why? According to Dr. Jaliman, the body produces acetylcholine, a chemical that can inhibit cell breakdown, as a response to exercise. For some people, the acetylcholine will disrupt skin cells, thus irritating the skin and creating a rash the same way histamine does.
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:
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.

A variation called vasculitic hives occurs in a small number of cases. In this condition the weals last more than 24 hours, they are often painful, may become dark red and may leave a red mark on the skin when the weal goes. Technically, this type of rash is not urticaria.
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.
Your doctor will be able to tell if you have hives by looking at your skin. If you suffer from any allergies and have a history of hives, it is even easier to reach a diagnosis. If you need to find out the cause of the allergic reaction, a blood test or a skin biopsy may be needed.
Diseases and medications can also cause low blood pressure. When the flow of blood is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidneys; the organs do not function normally and may be permanently damaged.

Many people have a sensitivity to latex which causes a contact dermatitis. The foods listed in the second table above contain chemicals that are similar enough to those found in latex that eating them can cause an allergic reaction. If you have a latex allergy, these foods off your shopping list.

Urticaria is diagnosed in people with a history of weals that last less than 24 hours with or without angioedema. A family history should be elicited. A thorough physical examination should be undertaken.
One study was performed on 45 medical students taking final exams to see if stress negatively affected their resistance to disease. Specifically, these students were studied three to four weeks prior to exams, then again during exams to see how they responded to a hepatitis vaccine. Compared to students who received the vaccine under relaxed conditions, the stressed students showed much weaker immune system responses to the vaccine.
Oral steroids (prednisone, [Medrol]) can help severe cases of hives in the short term, but their usefulness is limited by the fact that many cases of hives last too long for steroid use to be continued safely. Other treatments have been used for urticaria as well, including montelukast (Singulair), ultraviolet radiation, antifungal antibiotics, agents that suppress the immune system, and tricyclic antidepressants (amitriptyline [Elavil, Endep], nortriptyline [Pamelor, Aventyl], doxepin [Sinequan, Adapin]). Evidence to support the benefit of such treatments is sparse. In ordinary cases, they are rarely needed. A new treatment now indicated for chronic urticaria is the monthly subcutaneous injection of a monoclonal antibody, omalizumab (Xolair), directed against the IgE receptor on human mast cells.
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.
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.
Hi I have found out I have this and been on many antihistamines to try and control it but I am now on fexafenidine and these don’t seem to work at all some days when I have a flare up I look like I…

Patients with CSU have an increased frequency of Hashimoto’s thyroiditis. An association has been noted with the presence of antibodies to thyroglobulin, or a microsomal-derived antigen (peroxidase) even if patients are euthyroid. The incidence of thyroid autoantibodies in patients with chronic urticaria is approximately 24%. Thyroid function and thyroid antibodies should be checked in all patients with chronic urticaria. There are no data to suggest that either of these antibodies are pathogenic in terms of hive formation and it is believed that these are associated, parallel, autoimmune events.

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].
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 physician for diagnosis and treatment.
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 long time.
Angioedema, on the other hand, is usually not red or itchy, but tends to sting and burn, and can be described as “numbness.” This swelling can be severe, and if it affects a person’s ability to breathe, can be life-threatening.
Beyond allergic reactions, some medications are also associated with chronic hives. Non-steroidal anti-inflammatory drugs (NSAIDs) are the most notable, so your reaction could be due to something as common as aspirin. Antibiotics, codeine, morphine, and radiocontrast dye are also known to be triggers.
Hives caused by the radiocontrast dye, codeine, morphine, and aspirin are usually not triggered by the immune system, rather these drugs cause the direct release of histamine from specialized white blood cells called mast cells.
Inducible urticaria – sometimes called physical urticaria. This is a type of hives in which a rash appears when the skin is physically stimulated. The most common is called dermatographism (dermatographia) when a rash develops over areas of skin which are firmly stroked. In other cases, an urticarial rash is caused by heat, cold, emotion, exercise, or strong sunlight. See separate leaflet called Hives (Inducible Urticaria) for more details.
To know exactly what kind of hives one has, or to learn more about research into the immune basis of hives or about rarer forms of this condition, consult a physician. It is important, however, to keep in mind that most cases of urticaria are annoying, not serious, and almost always temporary.
If your hives last more than a month or if they recur over time, see an allergist, who will take a history and perform a thorough physical exam to determine the cause of your symptoms. A skin test and challenge test may also be needed to identify triggers.
Both Flonase and Nasacort are available without a prescription. These medications contain different steroids but both are meant to treat sinus congestion due to allergies.  Neither should be used in children without talking to your doctor first.  You can substitute Flonase for Nasocort, but you should use it regularly but shouldn’t use more than 1 spray in each nostril twice a day.  If you have diabetes, glaucoma, cataracts or liver disease, ask your doctor before using.

The older oral antihistamines (eg, hydroxyzine, diphenhydramine) are sedating and can cause confusion, urinary retention, and delirium. They should be used cautiously to treat urticaria in elderly patients.
Weals are due to release of chemical mediators from tissue mast cells and circulating basophils. These chemical mediators include histamine, platelet-activating factor and cytokines. The mediators activate sensory nerves and cause dilation of blood vessels and leakage of fluid into surrounding tissues. Bradykinin release causes angioedema.
It’s important that you talk to your doctor about your experience with CIU, sharing details about your symptoms. Think about your condition and write down what you are going through. In close partnership, you and your doctor can manage your disease together.
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.
Some people react to anything that makes them hot or sweaty with hives. This can be sunlight, exercise, hot baths, blushing or anger. These are tiny intensely itchy hives with a big red blotch around them and are called cholinergic urticarial.
Urticaria or hives, can be allergic or also non-allergic disease. For chronic and recurring Urticaria, you need homeopathy. After all, for how long will you keep taking antihistamines? At Life Force, Dr Shah is Urticaria expert having experience of Urticaria treatment of over 2700 cases.
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.

“hives pictures |cold urticaria underlying causes”

The most common foods that cause hives are nuts, chocolate, fish, tomatoes, eggs, fresh berries, and milk. Fresh foods cause hives more often than cooked foods. Certain food additives and preservatives may also be to blame.
Urticarial vasculitis is an eruption of erythematous wheals that clinically resemble urticaria but histologically show changes of leukocytoclastic vasculitis.[1, 2] Urticarial vasculitis may be divided into normocomplementemic and hypocomplementemic variants. Both subsets can be associated with systemic symptoms (eg, angioedema, arthralgias, abdominal or chest pain, fever, pulmonary disease, renal disease, episcleritis, uveitis, and Raynaud phenomenon). The hypocomplementemic form more often is associated with systemic symptoms and has been linked to connective-tissue disease (ie, systemic lupus erythematosus [SLE]).[3, 4, 5]

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.
The presence of systemic symptoms could mean the urticarial rash is not ordinary urticaria,” he said, suggesting that vasculitis, Schitzler’s syndrome, adult-onset Still’s disease, an autoinflammatory syndrome, or urticarial dermatitis could be at play.
Initially it is helpful to explain to patients what urticaria is and that very often it is not due to ‘an allergy’. They may be reassured that in nearly all cases there is no serious underlying medical problem causing the rash; that safe, effective treatments are available and the long-term prognosis is usually good. A patient information leaflet, such as that available from the British Association of Dermatologists [48], is helpful.
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.
The stress and anxiety bought on by an attack of hives can be countered with herbal teas such as peppermint or chamomile tea. These teas also have sedative properties and can help soothe the pain and itching symptoms of hives. Other stress busting activities like yoga and meditation can also help.

There are no routine diagnostic tests in chronic spontaneous urticaria apart from blood count and C-reactive protein (CBC, CRP), but investigations may be undertaken if an underlying disorder is suspected.
There has been a high incidence of autoantibody to thyroid glands reported among those with anti-Fc-receptor antibodies and it is suggested that yearly thyroid testing be done by the primary care physician.
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.
Simply put, external stressors plus cognitive, behavioral and social stressors have been shown to play a significant role in the intensity of itch, often providing an ever greater correlation than the actual dermatologic disease severity, according to Dr. Howard.
If hives are making it difficult to sleep, then it may be necessary to see a physician. This would be especially important if you are taking nonprescription antihistamines. If your hives last longer than two months, it is also likely you will benefit from visiting a physician.
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.
Oatmeal is a very effective natural remedy for urticaria. Place 2 heaped tablespoons of oatmeal in a bowl and add about half a cup of water to it. Make sure that the water is just enough to cover the oatmeal and keep the bowl aside. After 10 minutes or so you will find that the oatmeal has absorbed all the water in the bowl. Place a clean strip of cloth over a mug and then place the soaked oatmeal on the cloth. Slowly pour about ½ a cup of water over the oatmeal and allow it to collect in the mug below. This water will be slightly murky as it contains mucilage from the oatmeal. Apply this to your skin to reduce the itching and discomfort.

Most of the time, a doctor can diagnose hives just by looking at the skin. To find the cause, you be asked questions about your child’s medical history, recent exposure to allergic triggers, and daily stressors.
The important thing is that the patient is given enough medication (antihistamines, perhaps in conjunction with other drugs) to suppress the hives. Whatever it is that controls a patients hives, should be the daily regimen, taking the drugs every day, whether or not they have the hives on any given day. The idea is that one is preventing the hives from breaking out.

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.
The pathophysiology of urticarial vasculitis is similar to other forms of cutaneous small vessel leukocytoclastic vasculitis. Urticarial vasculitis is a type III hypersensitivity reaction in which antigen-antibody complexes are deposited in the vascular lumina. This reaction results in complement activation and chemotaxis of neutrophils. These cells release various proteolytic enzymes, such as collagenase and elastase, resulting in damage to the vascular lumina. Some authors have speculated that eosinophils may be involved in the early stages of the vasculitic lesions. Patients with hypocomplementemic urticarial vasculitis are more likely to show autoantibodies to C1q and vascular endothelial cells.[6, 7] The presence of antineutrophilic cytoplasmic antibodies is rare. Many patients ultimately prove to have SLE. Other etiologies include drug reactions and parasitic infections.[8]
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]
Can stress cause hives? The answer is definitely “yes.” Hives and stress can go hand-in-hand. When you experience excessive short or long term stress, it takes a toll on body’s immune system. Since the stress is throwing off your immune system, your body responds by internally sending out histamine to fend off your current health problem, which in this case is stress. Histamine release doesn’t make stress go away, but it can cause hives to start popping up in various places. Basically, this is an allergic reaction to stress and your body is sending out visible signals (hives) to let you know that it’s time to chill out. (18)
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.
Hives are a very itchy rash usually caused by an allergic reaction. Hives look like raised pink spots with pale centers on the skin. The spots range from 1/2 inch to several inches wide (hives often look like mosquito bites). The spots may be different shapes. The spots rapidly and repeatedly change in location, size, and shape. Giant hives are called angioedema. This can cause large swelling beneath the skin, especially of the face.

When we’re exposed to a stressful situation, our bodies prepare for confrontation. This “fight or flight” response is controlled by our hormones and nervous system and dates back to prehistory, as we prepared to fight or flee our stressor.
The immediate symptoms of this type are treated with antihistamines, epinephrine and airway support. Taking antihistamines prior to exercise may be effective. Ketotifen is acknowledged to stabilise mast cells and prevent histamine release, and has been effective in treating this hives disorder. Avoiding exercise or foods that cause the mentioned symptoms is very important. In particular circumstances, tolerance can be brought on by regular exercise, but this must be under medical supervision.[citation needed]
Localized cold urticaria, in which only certain areas of the body urticate with cold contact, has been reported after predisposing conditions such as cold injury; it has also been reported at sites of intracutaneous allergen injections, ragweed immunotherapy, or insect bites.
Antihistamines should be avoided where possible in pregnancy. There are no systematic studies of safety in pregnancy, and chlorphenamine is often the first choice if an antihistamine is required in this situation. Loratadine or cetirizine are preferred in women who are breast-feeding.
This chronic condition can also make your skin red and itchy. Although it’s most common in children, it can occur at any age. It generally starts as small, raised bumps. These bumps may leak fluid if scratched. The rash can form thickened areas of skin over a larger area, called plaques.
Delayed-pressure urticaria: Application of deep pressure to the skin produces swelling after 1-5 hours, like sitting on one spot for a prolonged period of time. The area will be deep and tender to touch.
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.
The hallmark red raised welts of hives sometimes have a pale center, can appear in clusters, and can change shape and location in a matter of hours. They can be from a few millimeters wide to as big as a dinner plate, and can itch, sting, or cause a burning sensation.

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 a person also has angioedema, there might be puffiness, swelling, or large bumps around the eyes, lips, hands, feet, genitals, or throat. In severe cases, swelling in the throat can cause breathing trouble and lead to a loss of consciousness.
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).
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.

Use rutin supplements. A number of herbs and supplements have natural anti-inflammatory activity. Rutin is a natural bioflavonoid found in citrus fruits and buckwheat. It can function to reduce inflammation and swelling by limiting the leakage from blood vessels.[15][16]
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.
Patients with chronic idiopathic urticaria often do not respond to antihistamines or other drugs commonly used. Omalizumab, a monoclonal antibody that can suppress certain allergic reactions, may help relieve symptoms, but experience with this use is limited.

Urticarial vasculitis is a condition characterized by inflammation of the small blood vessels in the skin. Signs and symptoms include an itching and burning sensation in the affected skin. Lesions (wheals) caused by urticarial vasculitis may also leave behind a bruise.
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!
Antihistamines: The once-daily non-sedating antihistamines are the mainstay of current urticaria treatment, but quadrupling the normal recommended dose is often necessary to obtain symptom control (for example Cetirizine 10 to 30mg, Loratadine 10 to 30mg or Fexofenadine 180 to 540mg).  Once the urticaria is controlled, the dose can slowly be reduced.  Older sedating antihistamines such as Chlorpheniramine, Diphenhidramine or Hydroxyzine may help at night with sleep disturbance from itching.  Tolerance to antihistamines can develop it may help to periodically rotate through different antihistamines. Ketotifen may be effective in children with its antihistamine and mast cell stabilising properties. If it is necessary to use antihistamines in pregnancy, Chlorpheniramine although sedating, is safest. Stomach ulcer treating Histamine H2 blockers such as Ranitidine or Cimetidine offer additive antihistamine effective if used with conventional antihistamine medication.
Your doctor may prescribe a cream or antihistamines to help with the itching. Good skin care is essential for prevention of an infection. For isolated or minor infected lesions, an antiseptic e.g. betadine can be applied. However, antibiotics may be necessary for severe or extensive infection.
Environmental Factors:  Exposure to pollen, dust, fungi, sudden changes in temperature, and even extreme temperatures are some of the triggers of acute urticaria. Some people may experience allergic reactions to high humidity levels.

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.
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
Diseases and medications can also cause low blood pressure. When the flow of blood is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidneys; the organs do not function normally and may be permanently damaged.
Clinical Context:  Although prednisone is most effective, adverse effect profiles preclude it from use as a first-line agent. Consider it only after failure of antihistamines, indomethacin, colchicine, dapsone, or hydroxychloroquine. Its effect on urticarial vasculitis likely is mediated by its anti-inflammatory effect. This class of medications decreases capillary permeability and inhibits the mitotic rate of lymphocytes.
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.
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:
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]
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.
Drugs that have caused allergic reactions evidenced as hives include codeine, dextroamphetamine,[7] aspirin, ibuprofen, penicillin, clotrimazole, trichazole, sulfonamides, anticonvulsants, cefaclor, piracetam, vaccines, and antidiabetic drugs. The antidiabetic sulphonylurea glimepiride, in particular, has been documented to induce allergic reactions manifesting as hives. Drug-induced hives has been known to have an effect on severe cardiorespiratory failure.[medical citation needed]
Recognize the symptoms. The symptoms and appearance of hives can be very short-lived, lasting only minutes, to very long term. The symptoms and appearance of hives can last for months and years. Hives can also appear on any area of the body, though the most common are the raised, itchy bumps that appear in the same area that was exposed to the allergen.

Acute viral illnesses in children can be associated with urticarial eruptions which last a few weeks and then spontaneously subside. This typically accompanies symptoms of viral rhinitis, pharyngitis, or bronchitis. When such patients are given an antibiotic, the cause of the hives becomes less clear because a drug reaction becomes an alternative possibility. If penicillin or related antibiotics have been given it is worth performing skin testing for penicillin and/or cephalosporin allergy, rather than making an unsubstantiated assumption that the child is “penicillin allergic.” Hepatitis B, infectious mononucleosis (EB virus) and a large number of helminthic parasites may be associated with hives in all age groups.
They released their second studio album Veni Vidi Vicious in April 2000 through Burning Heart Records. The band themselves described the album as being like “a velvet glove with brass knuckles, both brutal and sophisticated at the same time”. The album yielded the singles “Hate to Say I Told You So”, “Main Offender”, “Die, All Right!”, and “Supply and Demand.”
Hives caused by the radiocontrast dye, codeine, morphine, and aspirin are usually not triggered by the immune system, rather these drugs cause the direct release of histamine from specialized white blood cells called mast cells.

The purpose of this review is to discuss the association of CU with thyroid disease and other autoimmune diseases, as well as the implications that these associations hold for therapeutic intervention in CU.
Urticaria is characterized by itchy bumps or areas of raised skin that are light red in color and cause intense itching. This condition is commonly known as hives and while it is most commonly caused by an allergic reaction it can also have non-allergic causes. Urticaria is classified as either acute or chronic and this is dependant on how long the outbreak lasts. Outbreaks that last for less than 6 weeks are referred to as acute urticaria cases while those that last for longer periods are termed as chronic. Acute urticaria is generally the result of an allergic reaction while chronic urticaria often has autoimmune causes. An acute viral infection can also be a cause of acute urticaria. Hives are also known to be caused by local pressure, friction, extremes of temperature, and sunlight.
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.
“This subset — about 30 percent of patients who have been diagnosed with idiopathic urticaria — is the 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.”
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.

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.
Typically, acute and chronic display round or oval hives, occur over virtually any part of the body and last for hours or days. There are others forms of urticaria which show up in lines or odd shapes, appear on specific parts of the body and appear then disappear within two hours. This is urticaria which is triggered by a physical cause. There are several possible causes:
Mint oil cools the skin and reduces swelling and pain. Freeze fresh mint leaves and water to form ice cubes and place them over the rash for an alternative relief treatment. Make sure that you wrap the ice cubes in a cloth before applying them to the skin, as the direct application of ice can cause further skin damage.
The main treatment for acute urticaria in adults and in children is with an oral second-generation antihistamine chosen from the list below. If the standard dose (eg 10 mg for cetirizine) is not effective, the dose can be increased fourfold (eg 40 mg cetirizine daily). They are best taken continuously rather than on demand. They are stopped when the acute urticaria has settled down. There is not thought to be any benefit from adding a second antihistamine.
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.
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.
Studies have shown that a substantial number of patients with chronic urticaria have a positive autologous skin test, meaning that injection of the patient’s serum in a skin test leads to a significant wheal and flare reaction. A proportion of such patients (about 35%) have been found to have an IgG antibody directed against the alpha- subunit of the IgE receptor which experimentally can cause degranulation of histamine-containing cells (blood basophils or mast cells). A smaller proportion have anti-IgE antibodies (5%). This accounts for 40% of patients with CSU. Fifty percent of patients with CSU have circulating basophils that are hyporesponsive to activation by anti IgE due to high intracellular phosphatase levels and this reverts to normal during therapy or remission.  Mechanisms for histamine release caused by the aforementioned autoantibodies have been described but proof of their pathogenicity is lacking.  Yet virtually all diseases strongly associated with autoimmunity turn out to be autoimmune.
Insect bites are localised, often clustered in groups of 3–5 lesions, and they appear in crops. Bites persist for days. Close inspection reveals a central punctum. Chronic hypersensitivity to insect bites is often called papular urticaria.
This chronic condition can also make your skin red and itchy. Although it’s most common in children, it can occur at any age. It generally starts as small, raised bumps. These bumps may leak fluid if scratched. The rash can form thickened areas of skin over a larger area, called plaques.

Delayed-pressure urticaria: Application of deep pressure to the skin produces swelling after 1-5 hours, like sitting on one spot for a prolonged period of time. The area will be deep and tender to touch.
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.

Chronic idiopathic hives has been anecdotally linked to stress since the 1940s.[22] A large body of evidence demonstrates an association between this condition and both poor emotional well-being[23] and reduced health-related quality of life.[24] A link between stress and this condition has also been shown.[25] A recent study has demonstrated an association between stressful life events (e.g. bereavement, divorce, etc.) and chronic idiopathic urticaria[26] and also an association between post-traumatic stress and chronic idiopathic hives.[27]
Some people find it relaxing to engage in a hobby, others find spending time with a pet, drawing, painting or writing is helpful. Experiment with different activities, paying attention to how you feel after participating. Then, make sure to include time each day for those activities that make you feel more relaxed.

Alcohol: Alcohol allergies are rather rare and in most cases the reaction is brought on by the ingredients used to prepare the alcoholic beverage rather than the alcohol itself. For instance a person may suffer from an allergic reaction after drinking wine but the root cause would probably be the grapes that were used to make the wine. In the same way a person may believe that they are allergic to the alcohol in beer although they are actually allergic to the wheat or barley that is used to make the beer. Some people may even be allergic to the yeast that is used in the fermentation process.
Hives usually appear suddenly, sometimes because of an allergic reaction or being stung by a nettle. They form in response to histamine, which causes surrounding tissues to swell and become red. Histamine and other chemicals cause blood vessels to dilate and become leaky allowing fluid from the blood to leak out of the blood vessels causing itchiness and swelling.
An allergic skin condition featuring itchy, raised, pink areas surrounded by pale skin. These patches persist for periods of half an hour to several days and then resolve. Urticaria may result from sunlight, cold, food or drug allergy, insect bites, scabies, jelly fish stings or contact with plants. Treatment is with antihistamine drugs or corticosteroids. Also known popularly as nettle rash or hives.
Stress hives suck, but they’re not the end of the world. If you have chronic urticaria, it’s a good sign that stress is really eating away at you and having a negative effect on your life. My goal with TSM is to help you manage stress and live a more enjoyable life. Don’t let stress control your life.
A food allergy attack can last for quite a while as the allergen remains within your system and this increases the severity of the reaction. Drink plenty of fluids such as fresh fruit and vegetable juices as this will help to get rid of the allergen and reduce the recovery period.
It stands in contrast to the linear reddening that does not itch seen in healthy people who are scratched. In most cases, the cause is unknown, although it may be preceded by a viral infection, antibiotic therapy, or emotional upset. Dermographism is diagnosed by taking a tongue blade and drawing it over the skin of the arm or back. The hives should develop within a few minutes. Unless the skin is highly sensitive and reacts continually, treatment is not needed. Taking antihistamines can reduce the response in cases that are annoying to the patient.[citation needed]
These are distinguished by finding normal or lowered levels of complement proteins on blood testing. Although both types may be associated with systemic symptoms such as angioedema, abdominal or chest pain, fever, and joint pain, this is more apparent in the hypocomplementaemic form. This form has also been linked to the connective tissue disease systemic lupus erythematosus (SLE).
Chronic hives don’t put you at any sudden risk of a serious allergic reaction (anaphylaxis). If you do experience hives as part of a serious allergic reaction, seek emergency care. Signs and symptoms of anaphylaxis include dizziness, trouble breathing, and swelling of your lips, eyelids and tongue.
Relax. While it is not known exactly how stress and hives are related, stress does seem to put a person at higher risk for having hives. Reduce your stress levels by trying to relax. Take time out of you schedule everyday to take part in relaxing activities, such as a leisurely walk, reading a book, gardening, or watching a movie.
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.
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. 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.
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.
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.
If your GP thinks that it’s caused by an allergic reaction, you may be referred to an allergy clinic for an allergy test. However, if you’ve had urticaria most days for more than 6 weeks, it’s unlikely to be the result of an allergy.
When you’re all stressed out, your body releases hormones and other chemicals, including histamine, the powerful chemical that leads to allergy symptoms. While stress doesn’t actually cause allergies, it can make an allergic reaction worse by increasing the histamine in your bloodstream.
Chronic urticaria is usually treated with antihistamine medication. Antihistamines are commonly available as over-the-counter medications. They can often be effective in stopping itch and preventing future outbreaks of urticaria.  Medication usually needs to be continued for many weeks and long term treatment may be required in some cases to keep the condition under control.
Diet plays a very important role in the treatment of urticaria, especially in the case of a food allergy. The first step in planning your diet for urticaria is to avoid the food that is causing the reaction. If you are unsure as to what food caused your reaction, you would need to make a list of all the foods that you have consumed in the last 24 hours and avoid all of them if possible. Try to recall if your diet in the last 48 hours included foods that you do not usually consume. Take away food, especially Chinese food is often associated with food allergies due to the spices and condiments that are used to prepare them. 
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 very best way to get rid of stress hives is to remove as much stress from your life as possible. There are so many effective ways to reduce stress on a daily basis. Find what works best for you and make it a part of your routine. Exercise is always one of my stress boosters. Other great ideas for stress hives treatment, and hives treatment in general, include yoga, massage, journaling and prayer.
If your hives last more than a month or if they recur over time, see an allergist, who will take a history and perform a thorough physical exam to determine the cause of your symptoms. A skin test and challenge test may also be needed to identify triggers.
Urticaria has been reported with infectious diseases. Viral infections associated with acute urticaria include acute viral syndromes, hepatitis (A, B, and C), Epstein-Barr virus, and herpes simplex virus. Streptococcal infection (see the photograph below) has been reported as the cause of 17% of acute urticaria cases in children. [12] Urticaria has also been reported with chronic parasitic infections. [13]
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.
Urticaria results from the release of histamine, bradykinin, leukotriene C4, prostaglandin D2, and other vasoactive substances from mast cells and basophils in the dermis. [2] These substances cause extravasation of plasma into the dermis, leading to the urticarial lesion. The intense pruritus of urticaria is a result of histamine released into the dermis. One study showed that D-dimer levels correlate with the severity of acute urticaria and may serve as a marker of disease severity. [75]  
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]

Stress hives are indeed caused by too much stress, tension or anxiety in your life. When you expose your body to excessive stress, whether it be over a short period of time or a long period of time, your body’s immune system starts to falter. When your immune system is off kilter, it starts sending histamine into the body to fight off what is ailing you – stress. In essence, your body forms an allergic reaction to stress. Unfortunately, stress can not be eliminated with histamine, so instead, the histamine just causes hives to appear on your face, neck, chest and other parts of your body.
Diagnose hives. The diagnosis of hives is generally straightforward and requires only a visual examination. If you were unable to find the allergen causing your hives on your own, your doctor can run tests when you are diagnosed to determine what causes your hives. He or she does this by performing an allergy test that test for skin reactions to a variety of substances.

Angioedema, on the other hand, is usually not red or itchy, but tends to sting and burn, and can be described as “numbness.” This swelling can be severe, and if it affects a person’s ability to breathe, can be life-threatening.
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.
Research shows that up to 50% of people with CIU continue to have hives after treatment with antihistamines. Omalizumab, which is injected under the skin, has been shown to relieve the itch and clear hives in some people with CIU. In one research study, 36% of patients treated with omalizumab reported no itch and no hives after 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 physician for diagnosis and treatment.
This medication must be injected under the skin. This option is only available if your hives have lasted for months or years. Common side effects are headache, dizziness, inner ear pain, and cold symptoms.
Hives (urticaria) are raised, red spots on the skin that often itch. Hives are usually indicative of an allergic reaction. Hives are a common reaction in people who have allergies. A number of substances can trigger an outbreak of hives, including foods, medications, pollen, animal dander, or insect bites.
Like other medications used to treat urticarial vasculitis, antimalarials are believed to exert their effect by their anti-inflammatory properties. Antimalarials reduce neutrophilic chemotaxis. In addition, they increase pH in lysosomes, which may affect antigen presentation. This class of medications usually is effective only in cutaneous disease.
“There is more and more evidence that antidepressants may be less useful than psychotherapy and cognitive behavioral therapy in treating mild-to-moderate depression,” Dr. Howard says. “Any patient who starts an antidepressant needs to be followed closely and monitored for the emergence of manic or hypomanic symptoms.”

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.
In 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.
Cold urticaria is usually idiopathic, but it may occur in 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].

Where a standard dose of a non-sedating H1 antihistamine is ineffective, doses of up to four times the standard dose may be used, or another antihistamine added. Evidence for up-titrating the dose varies[7]. An additional sedating antihistamine such as chlorphenamine may be useful if itch is interfering with sleep. Avoid hydroxyzine if the person has a prolonged QT interval or risk factors for QT interval prolongation in line with recent guidance from the Medicines and Healthcare products Regulatory Agency (MHRA)[8].
A food allergy attack can last for quite a while as the allergen remains within your system and this increases the severity of the reaction. Drink plenty of fluids such as fresh fruit and vegetable juices as this will help to get rid of the allergen and reduce the recovery period.
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.
Physical Urticaria (Inducible Urticaria) in its most simple form usually presents as linear scratches or Dermatographism.   Physical Urticaria is triggered by common physical stimuli such as heat, cold, sun exposure, vibration, exercise, deep pressure and even occasionally from water exposure (Aquagenic). The weals occur within minutes of the stimulus and disappear rapidly within an hour or two. Just to complicate matters, Physical Urticaria may occur together with Chronic Idiopathic Urticaria.  While Contact Urticaria an immediate allergy occuring after skin contact with fresh foods (potato, shellfish), pet saliva or latex and settles within a few hours.
Heat-induced urticaria:This is a common form of chronic urticaria (5-7%). It appears as small wheals (1-2 mm 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.
The weals are commonly 1-2 cm across but can vary in size. There may be just a few but sometimes many develop over various parts of the body. Sometimes weals next to each other join together to form larger ones. The weals can be any shape but are often circular. As a weal fades, the surrounding flare remains for a while. This makes the affected area of skin look blotchy and red. The blotches then fade gradually and the skin returns to normal.
Angioedema – swelling of tissue beneath the surface of the skin – can be mistaken for or associated with hives. It can be caused by allergic reactions, medications or a hereditary deficiency of some enzymes. The following symptoms may indicate angioedema:

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.
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]
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.
Pressure hives produces deep and painful local swelling. The swelling can occur immediately or several hours later. This type of urticaria can be triggered by prolonged sitting. It is also triggered but the wearing of tight clothing and consequently is seen in areas such as the waist/belt line, under elastic bands such as panties, socks or wristbands. Choosing appropriate clothing and/or taking regular breaks from sitting, usually controls pressure urticaria. If medication is needed, steroids are usually administered for a short time.
