“define urticaria _hives caused by stress”

According to the American Osteopathic College of Dermatology, about half the cases of chronic idiopathic hives are due to immune systems that attack the body’s own tissues (also known as autoimmunity). Thyroid disease is the most commonly reported autoimmune condition in people with chronic hives, followed by rheumatoid arthritis and type 1 diabetes. A study published in September 2013 in the European Journal of Dermatology found that celiac disease is also associated with chronic hives.
Tests are sometimes done when hives go on for long periods or when unusual symptoms are occurring around the same time. This is to exclude other diseases, which may appear as hives first and other conditions later. If hives are associated with high fever, bruising, bleeding into the skin, purple lumps that last for several days or sore joints a doctor’s appointment should be arranged promptly.
In addition, the mission of AAFA’s Web site is to provide online access to AAFA’s reliable, validated asthma and allergy information and tools to families, patients, parents, healthcare providers, policymakers and others.
There is a lot that we still do not understand about urticaria causes although we do know that there are certain triggers and certain reactions that could cause the symptoms associated with utricaria to flare up. The absence of any well defined or clear cause of urticaria does to a large extent limit our ability to deal with the problem. The point to note is that urticaria is not always caused through or because of an allergy and there is no definitive urticaria cure. Non–allergic causes are connected to auto- immunity, to hormone interplay to stress factors, and more. These are some of the more common urticaria causes or triggers:
The following pictures are from other people that got a rash from stress. While a stress rash is very common, it is not an incurable condition. So if you are wondering “can anxiety cause a rash?” the answer is yes, and the solution is OxyHives. If none of these pictures look like your stress related rash, please keep in mind that everyone’s rash will look differently depending on various other factors.
What causes hives? Hives are typically caused by an allergic reaction. The allergy can be to a food or medication. When your body is allergic to something, it can release chemicals that make your skin develop hives. An infection or emotional stress can also cause hives.
Angioedema is a similar skin issue to hives, but it usually last longer than hives. Swelling is under the skin instead of on the surface. With angioedema, a person typically has deep swelling around the eyes and lips and, sometimes, of the genitals, hands and feet. In rare cases, angioedema of the throat, tongue, or lungs can block the airways, making it hard to breathe. This can be life threatening. (23)
cold urticaria urticaria precipitated by cold air, water, or objects, occurring in two forms: In the autosomal dominant form, which is associated with fever, arthralgias, and leukocytosis, the lesions occur as erythematous, burning papules and macules. The more common acquired form is usually idiopathic and self-limited.
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.
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.
If home and natural remedies aren’t enough to help your hives, over-the-counter (OTC) treatments may be your best bet. Not only can OTC options relieve itching and irritation, they can target your body’s histamine response, which is what causes hives to appear.
In many cases, a single attack of hives is due to an infection or virus and these go away within a few days to a few weeks. Some people get repeated attacks that occur as an allergic reaction to a variety of things (foods, most commonly nuts, chocolate, fish, tomatoes, eggs, fresh berries and milk, insect stings, and medications). In this case, they usually break out within a few hours of the exposure. Usually, the patients figure out the cause by themselves, and they never bother coming to a doctor.
This corticosteroid is taken orally. You should only use it for a short period of time as directed by your doctor. Corticosteroids can have side effects, especially if taken for extended periods of time. Side effects can include:
While hives do have many factors that can be used in the distinguishing of them, perhaps the most common of all symptoms is the appearance of urticaria, or welts. These welts are red, itchy and usually appear quickly, only to dissipate shortly after, but depending on the allergen, can come back and are replaced by others.

Omalizumab, or Xolair, is an injectable drug that blocks immunoglobin E, a substance that plays a role in allergic responses. It reduce symptoms of chronic idiopathic urticaria, a type of hives of unknown origin that can last for months or years.
When my son came in contact with caterpillars he would break out in giant hives all over his body. THANK GOD FOR THE SASAFRASS TREE!!! I would make him a cup of tea and within 30 minutes the hives disappeared completely when Benadryl never did. Can be bought at your local grocers.

“urticaria and angioedema +hives and itching”

Patients with urticarial vasculitis present with an urticarial eruption, often accompanied by a painful or burning sensation. Lesions are generalized wheals or erythematous plaques, occasionally with central clearing, lasting for more than 24 hours in a fixed location (in contrast to urticaria, which resolves in minutes to hours or migrates continually). Petechiae may be noted within the lesions, and they may resolve with ecchymoses or postinflammatory hyperpigmentation. Patients may have photosensitivity, lymphadenopathy, arthralgia, angioedema (40%), fever, abdominal pain, dyspnea, and pleural and pericardial effusions.[4] Most cases of urticarial vasculitis are idiopathic.
Despite the reputation of hives being an “allergic” condition, there is often no obvious connection to any provoking substance. In this situation, random allergy testing is not usually helpful. If you know what is causing your hives, then avoiding the cause, if possible.
Anti-inflammation medications. Oral corticosteroids, such as prednisone, can help lessen swelling, redness and itching. These are generally for short-term control of severe hives or angioedema because they can cause serious side effects if taken for a long time.
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.
Understand what causes the hives. Anyone can get hives. About 20% of the population have experienced them at some point in their lives.[2] During an allergic reaction, certain skin cells, such as the mast cells that contain histamine and other chemical messengers like cytokines, are stimulated to release the histamine and other cytokines. These increase the amount of leakage from the tiny blood vessels in the skin and cause the swelling and itching that is so characteristic of hives.[3]
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.
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, and 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).
In a November 2008 interview with leading Swedish newspaper Dagens Nyheter, Swedish rapper Petter announced that the Hives were working on a new version of his track “Repa skivan” for his upcoming album.[24]
If a specific urticarial trigger can be found, then avoiding that trigger is the most sensible course of action, but most often no underlying cause is ever found.  The main focus of treatment is trying to alleviate symptoms while the urticaria slowly “burns” itself out and eventually clears – a process that may take many months or even some years.
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.
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.
Skin biopsy in patients in whom vasculitis is suspected: the lesions last for more than 24 hours, are painful and usually heal by leaving hyperpigmentation on the area of the lesions in urticarial vasculitis (24).
Clinical Context:  Colchicine is an alkaloid extract that inhibits microtubule formation. It is often used for the treatment of acute gout. Colchicine has been reported effective for urticarial vasculitis. It concentrates well in leukocytes and reduces neutrophilic chemotaxis and motility. Histologically, urticarial vasculitis presents with neutrophil involvement; therefore, colchicine possibly is useful. However, drug’s effect has not been proven in clinical trials.
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.
Infections and Infestations: Insect bites, frequent fungal and bacterial infections of the urinary tract, viral infections like hepatitis, worm infestations such as tapeworms and round worms can cause acute allergies.
The skin reaction usually becomes evident soon after the scratching, and disappears within 30 minutes. Dermatographism is the most common form of a subset of chronic hives, acknowledged as “physical hives”.[citation needed]

Exercise daily. Even if you only have time to take a walk, exercise helps reduce stress hormones that may cause you to feel keyed up. And remember, exercise produces epinephrine, which acts as a natural decongestant, helping you breathe better.

“hives and swelling _chronic rash”

Kids with bad allergies should carry an injectable shot of epinephrine to prevent life-threatening allergy attacks. If your child is at risk, the doctor will teach you and your child how to safely give an injection in the event of a severe allergic reaction.
“So, on the flip side of this, we can ask, ‘How can psychological interventions bolster the immune system and relieve somatic symptoms?’ Buffet in 2003 showed improvement in urticarial wheals after subcutaneous injection with histamine when treated with hypnosis and relaxation techniques (Buffet M. Ann Dermatol Venereol. 2003;130(1):S145-S159),” she says.
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 most common symptoms are hives that cause itching, pain and a burning feeling. Skin patches often are red-rimmed with white centers, and unlike common hives may have petechia, or bleeding under the skin. The patches can be present for days and result in skin discoloration as they heal. Some patients may also have fevers, joint and abdominal pain, shortness of breath and swollen lymph glands. Sometimes urticarial vasculitis even causes injury to vital organs including the gut, lungs and kidneys.

Angioedema is similar to hives,[34] but in angioedema, the swelling occurs in a lower layer of the dermis than in hives,[35] as well as in the subcutis. This swelling can occur around the mouth, eyes, in the throat, in the abdomen, or in other locations. Hives and angioedema sometimes occur together in response to an allergen, and is a concern in severe cases, as angioedema of the throat can be fatal.
This antibiotic is available topically and as an oral medication. This medication can treat inflammation caused by hives or other skin conditions caused by bacterial infection. It’s important to take all antibiotics prescribed.
What causes hives? Hives are typically caused by an allergic reaction. The allergy can be to a food or medication. When your body is allergic to something, it can release chemicals that make your skin develop hives. An infection or emotional stress can also cause 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 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.

Low blood pressure, also referred to as hypotension, is blood pressure that is so low that it causes symptoms or signs due to the low flow of blood through the arteries and veins. Some of the symptoms of low blood pressure include:
a pruritic skin eruption characterized by transient wheals of varying shapes and sizes with well-defined erythematous margins and pale centers. It is caused by capillary dilation in the dermis that results from the release of vasoactive mediators, including histamine, kinin, and the slow reactive substance of anaphylaxis associated with antigen-antibody reaction. It may be a reaction to drugs, food, insect bites, inhalants, emotional stress, exposure to heat or cold, or exercise. Treatment includes antihistamines and removal of the stimulus or allergen. Also called hives. See also angioedema, cholinergic urticaria. urticarial, adj.

Over half of all cases of chronic idiopathic hives are the result of an autoimmune trigger. Roughly 50% of patients with chronic urticaria spontaneously develop autoantibodies directed at the receptor FcεRI located on skin mast Chronic stimulation of this receptor leads to chronic hives. Patients often have other autoimmune conditions, such as autoimmune thyroiditis, celiac disease, type 1 diabetes, rheumatoid arthritis, Sjögren’s syndrome or systemic lupus erythematosus.[6]

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
Past medical history should include a detailed allergy history, including known atopic conditions (eg, allergies, asthma, eczema) and known possible causes (eg, autoimmune disorders, cancer). All drug use should be reviewed, including OTC drugs and herbal products, specifically any agents particularly associated with urticaria (see Table: Some Causes of Urticaria). Family history should elicit any history of rheumatoid disease, autoimmune disorders, or cancer. Social history should cover any recent travel and any risk factors for transmission of infectious disease (eg, hepatitis, HIV).
In addition to the skin lesions, patients with urticarial vasculitis may also develop systemic symptoms including photosensitivity, swollen lymph nodes, joint pain (50%), fever, abdominal pain (20%), difficulty breathing, and lung and kidney problems.
HUV is diagnosed where the patient has the main symptoms of Urticarial Vasculitis combined with lower than normal levels of C1q complements and raised levels of anti-C1q antibodies (antibodies that attack the C1q complements). HUV is a more severe form of Urticarial Vasculitis and is likely to include symptoms such as purple or dark red spots or rash on the skin (a typical vasculitic rash); arthritic joint pain; breathing difficulties such as asthma, and stomach pains. Some regard HUV as a form of SLE (Lupus), although HUV patients usually test Anti-Nuclear Antibody (ANA) negative instead of the normal positive result for Lupus patients.

Urticaria (or ‘hives’ or ‘nettle rash’) consists of blancheable, erythematous, oedematous papules or ‘weals’ (Fig. 1). These weals vary in size from 1 mm to many centimetres –‘giant urticaria’, and are usually intensely itchy. They are caused by vasoactive mediators, predominantly histamine, released from mast cells. In the vast majority of cases the weals are transient, lasting for only a few hours in any one place, but with new weals appearing in other places. This means that most urticarial rashes ‘move’ around the body – a useful pointer from the clinical history that the rash is urticarial. Urticaria is to be distinguished from ‘angioedema’, which is well-demarcated swelling, occurring within deep skin structures or in subcutaneous tissue (Fig. 2) and caused mainly by bradykinin production. Angioedema is not itchy, but may be painful. In about 50% of patients urticaria occurs alone; in about 40% of patients urticaria occurs with angioedema and in about 10% of patients angioedema occurs alone [1]. The aetiology of isolated angioedema is very often different from that of urticaria or urticaria with angioedema. The topic of isolated angioedema is to be reviewed in a further article in this series.
Acute hives can be related to other infections such as strep throat, athlete’s foot, mononucleosis, and coxsackie viruses. Though they’re not viral infections, both intestinal worms and malaria can also cause urticaria.
Stress can wreak havoc on your physical and emotional health. You may feel overwhelmed or anxious the source of your stress. If you’re experiencing physical symptoms like a rash, stress may be amplified.
The diagnosis is usually made clinically and on history – particularly in acute ordinary urticaria – and no investigations are needed. It can be established once it has been shown that individual lesions only last a few hours. A detailed history may point to a trigger in some cases.

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.
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]
Urticaria, also known as hives, is an outbreak of swollen, pale red bumps or plaques (wheals) on the skin that appear suddenly — either as a result of the body’s reaction to certain allergens, or for unknown reasons.
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.

The band claims it was formed in 1993 (although formed in 1989 under a different name and sound) under the guidance of Randy Fitzsimmons. Fitzsimmons suggested that they form a garage rock band. He gave each band member a letter asking them to start the band. Fitzsimmons allegedly acts as a songwriter and manager for the band. The band recorded a demo titled Sounds Like Sushi in 1994. The following year they were signed to Burning Heart, a Swedish skate punk record label. The following year they released their debut EP Oh Lord! When? How? Almqvist decided to promote the band to Burning Heart.[4]
Hives can also cause deeper swellings in the skin and mucosa called angioedema. These swellings are often bigger, last longer, may itch less, sometimes hurt or burn and respond less well to antihistamines. Large swellings over joints, for example, can cause pain that feels like arthritis even if the joint is not involved. Angioedema most frequently affects the face and lips. Although hives and facial swelling can be uncomfortable and cosmetically embarrassing, they are not usually dangerous.  Information on angioedema is available on the ASCIA website www.allergy.org.au/patients/skin-allergy
Occasionally, a person will continue to have hives for many years. These hives, called chronic urticaria, can be one of the most frustrating problems dermatologists see in their patients. This is defined as hives lasting longer than 6 weeks. Patients like this come in miserable and worried with this problem, often having seen multiple specialists. Neither the patient nor the doctor can determine the cause of the hives. Patients will often say, “It has got to be something causing these hives.” The truth is hard to accept for some patients.

“hives and itching -purificar agua”

Although sinusitis, cutaneous fungal infections, Helicobacter pylori infection, or other occult infections have been reported in the literature to cause urticaria, the data are not strongly supported. [14, 15, 16, 17, 18]

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.

There are numerous possible causes of hives, as they occur when a chemical called histamine is released in the skin. This can happen as a result of allergies, insect bites or stings, infections, exposure to certain chemicals, sunlight, heat or cold, and in response to some medications (often antibiotics or painkillers). 
Chronic hives don’t put you at any sudden risk of a serious allergic reaction (anaphylaxis). But 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.
If you suffer with allergy symptoms, you know all about the stress of having a chronic condition. Not only is it difficult to breathe with allergy symptoms, but poor sleep can lead to fatigue and problems concentrating. Allergy medicines can cause appetite changes, low energy, and even irritability. All you want is relief: from the stress, the symptoms, all of it.
If hives are making it 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.
Acute urticaria, which is an allergic (IgE-mediated) reaction, is common in both children and adults. This type of urticaria is a self-limiting process that occurs when mast cells in the skin are activated, degranulate, and secrete histamine, leukotrienes, platelet activating factor (PAF), enzymes such as tryptase and chymase, cytokines, and chemotactic cytokines (chemokines). When an allergen (for example, a food) to which the person is allergic arrives via the bloodstream to mast cells in the skin, it binds to the IgE, and the mast cells become activated, and degranulate. Allergens that can result in acute urticaria include foods, drugs (particularly antibiotics such as penicillin), and venoms from bee, wasp, yellow jacket, hornet, or fire ants. Virtually any allergen that can be disseminated throughout the body, and to which there is an IgE response, has the potential to cause generalized urticaria.
In acute forms of urticaria and angioedema, a history of the events surrounding the outbreak is the most important information that can be obtained. Here are three common questions your allergist may inquire about:

“urticaria def _hives all over my body”

Urticarial Vasculitis is a form of cutaneous vasculitis characterised by inflammation of the small blood vessels. Urticarial Vasculitis can be classified into three subtypes. All are defined by a measure of the “complement” levels in the blood. The complement system is a set of proteins that contribute to and amplify immune responses. They play a role in some, but not all, autoimmune disorders including some forms of Urticarial Vasculitis.
Swellings, known as wheals, appear as a rash on the skin. They are usually pink or red, with an oval or round shape. They can range from a few millimeters to several inches across. can be extremely itchy, and they have a red flare around them.
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.

The most important part of the investigation of a patient with urticaria is to take a detailed history [43]. This should include structured questions about the many possible clinical causes of urticaria (see above); the frequency, timing and duration of attacks; whether the patient has developed more severe allergic symptoms such as angioedema or wheezing in association with the urticaria; and whether there are any symptoms suggestive of an underlying medical condition such as a connective tissue disease and/or urticarial vasculitis. Photographs may be helpful in confirming the diagnosis and patients may have compiled a symptom diary, which is sometimes useful when trying to identify possible triggers for the rash.
In addition to this, it would be wise to stick to a bland diet for a few days or until the symptoms subside. Avoid foods like shellfish, eggs, and pineapples as they could aggravate your condition. It would also be best if you also avoid milk and milk products, eggs, and soy products.

Hives can also be classified by the purported causative agent. Many different substances in the environment may cause hives, including medications, food and physical agents. In perhaps more than 50% of people with chronic hives of unknown cause, it is due to an autoimmune reaction.[6]
Chizzola maculae is a very specific skin lesion due to fluoride exposure. The size of a coin, these lesions may resemble small blue bruises or be wholly pink. Doctors George Waldbott and V. A. Cecilioni named the lesions after a town in Italy, where they were common in young women and children.[17] According to Waldbott, chizzola maculae are early symptoms of fluoride intoxication.[18][19]
Although rosacea can affect anyone, it’s most common in middle-aged women who have fair skin. There’s no cure for rosacea, so treatments focus on management techniques. This includes wearing a broad-spectrum sunscreen and moisturizing frequently.
Although systemic treatment is best avoided during pregnancy and breast feeding, there have been no reports that second-generation antihistamines cause birth defects. If treatment is required, loratidine and cetirizine are currently preferred.
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.
Asthma triggers are substances, conditions or activities that lead to symptoms of asthma.Asthma symptoms include difficulty breathing, coughing, wheezing and shortness of breath. These symptoms can…
Treatment depends on severity, specific disease manifestations, and a balance between efficacy and drug toxicity and/or side effects. Ideally, non-sedating antihistamines should be tried first, including increased doses as described above for physical urticarias controlled trails demonstrate efficacy at 4 times the dose typically used for allergic rhinitis. The first generation antihistamines such as hydroxyzine or diphenydramine at 25-50 mg four times daily can be employed if the non-sedating, second-generation agents are insufficient. H2-receptor antagonists offer a little more global blockade of histamine receptors by inhibiting H2 receptors once H1 receptor blockage is maximal. There are 10-15% H2 receptors on venular endothelial cells. Leukotriene antagonists (montelukast, zafirlukast) can be tried in patients with severe symptoms but they may still not be satisfactorily controlled with the above-mentioned combinations. Alternate-day corticosteroids, eg, prednisone 10-25 mg every other day can be employed with gradual tapering at a rate of 2.5-5.0 mg every 2-3 weeks or 10-15 mg daily with taper of 1 mg/week. Another approach, and one that may be employed when use of corticosteroids is relatively contraindicated or when steroid side-effects prohibit their use, is cyclosporine. A typical dose range in adults is 200-300 mg/day, to be tapered to the lowest effective dose once a response is obtained. Monitoring of blood pressure and kidney function (urinalysis, BUN, creatinine) needs to be done on a regular basis.  The latest therapy is omalizumab supported by phase 1, 2, and three phase 3 trials.  It has the best efficacy to side effect profile and once approved for this indication (being reviewed currently) may supplant any use of sedating antihistamines once high-dose non-sedating agents fail.  H2 blockers and leukotriene antagonists may or may not be added next, but corticosteroids can be eliminated for chronic use, and cyclosporine reserved for omalizumab failures.
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).
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.
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.

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]

Urticaria typically looks like a raised rash that may be a normal skin colour or pinkish or red in colour. The rash may anywhere on the body and often starts off as small round spots that quickly enlarge and spread.
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.
If you have a bad allergic reaction, like shortness of breath, talk to your doctor about a prescription medicine called an “auto-injector.” This medicine stops the allergic reaction when you inject it into your thigh. Follow your doctor’s advice on how to use this medicine.
Urticaria, commonly referred to as hives, appears as raised, well-circumscribed areas of erythema and edema involving the dermis and epidermis that are very pruritic (see the image below). It may be acute (<6 wk) or chronic (>6 wk). Urticaria may be confused with a variety of other dermatologic diseases that are similar in appearance and are also pruritic; usually, however, it can be distinguished from these diseases by an experienced clinician.

Antileukotrienes (eg, montelukast), which may provide additional benefit in some selected patients when combined with an H1 antihistamine; there is little evidence that they are effective as monotherapy.
Low blood pressure, also referred to as hypotension, is blood pressure that is so low that it causes symptoms or signs due to the low flow of blood through the arteries and veins. Some of the symptoms of low blood pressure include:
If you have already been diagnosed with CIU, know that you are not alone. In the U.S., around 1.5 million people suffer from this form of chronic hives. Women are twice as likely to get CIU, and most cases appear between the ages of 20 and 40.

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.
Urticaria, commonly known as hives, is a distressing disorder affecting up to 20 percent of the population at some point in their lives. The swelling that sometimes accompanies urticaria, called angioedema, can lead to swelling of the face, hands and feet.

Patients with urticarial vasculitis present with an urticarial eruption, often accompanied by a painful or burning sensation. Lesions are generalized wheals or erythematous plaques, occasionally with central clearing, lasting for more than 24 hours in a fixed location (in contrast to urticaria, which resolves in minutes to hours or migrates continually). Petechiae may be noted within the lesions, and they may resolve with ecchymoses or postinflammatory hyperpigmentation. Patients may have photosensitivity, lymphadenopathy, arthralgia, angioedema (40%), fever, abdominal pain, dyspnea, and pleural and pericardial effusions.[4] Most cases of urticarial vasculitis are idiopathic.
Antihistamines – available either over the counter or by prescription – are a frequently recommended treatment for hives. They work by blocking the effect of histamine, a chemical in the skin that can cause allergy symptoms, including welts. Low-sedating or nonsedating antihistamines are preferred. They are effective and long-lasting (may be taken once a day) and have few side effects. Your allergist may recommend a combination of two or three antihistamines to treat your hives, along with cold compresses or anti-itch salves to ease the symptoms.
The cause of chronic hives can rarely be determined.[28] In some cases regular extensive allergy testing over a long period of time is requested in hopes of getting new insight.[29][30] No evidence shows regular allergy testing results in identification of a problem or relief for people with chronic hives.[29][30] Regular allergy testing for people with chronic hives is not recommended.[28]

They have one compilation album, Your New Favourite Band (2001) and they have issued a live DVD, Tussles in Brussels (2005).[3] The Black and White Album has been their most successful as of December 2017.
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.
Stress hives are red, raised swollen areas and bumps (AKA stress bumps) that appear on your skin, that develop due to too much stress or anxiety in your life. Stress hives can itch like crazy, giving you the feeling like ants or spiders are crawling over your skin. The only way to get rid of your stress hives is to remove all the stress and anxiety form your life. Because this is a near impossibility for most people, there is one stress hives treatment, known as OxyHives, that can be taken that reduces the swelling and itchy feeling within 2 hours.
Certain people can develop recurrent hives from sunlight, cold, pressure, vibration or exercise. These are called the physical urticarias. If hives develop from scratching or firmly rubbing the skin it is called dermatographism. It is the most common of the physical urticarias and it affects about 5 percent of the population. It doesn’t always itch. This condition sometimes also occurs along with other forms of hives.

How do you get hives? Hives are not something you can “catch” from anyone. Rather, they are your body’s response to something it ingests or experiences. The cause of hives can be a certain food, drug, infection or stress. You might be surprised to learn that stress is one of the most common causes of acute hives, along with allergies and infectious causes. Hives can literally occur at any age and appear anywhere on the body. It is estimated that one in every five people will be affected by a hives outbreak at some point in his or her life. (2)
Infections and Infestations: Insect bites, frequent fungal and bacterial infections of the urinary tract, viral infections like hepatitis, worm infestations such as tapeworms and round worms can cause acute allergies.
Urticarial Vasculitis is a form of cutaneous vasculitis characterised by inflammation of the small blood vessels. Urticarial Vasculitis can be classified into three subtypes. All are defined by a measure of the “complement” levels in the blood. The complement system is a set of proteins that contribute to and amplify immune responses. They play a role in some, but not all, autoimmune disorders including some forms of Urticarial Vasculitis.
This oral antihistamine can reduce the rash and other symptoms, like itching, by working from the inside out. Be sure to follow the dosage instructions on the package. The medicine usually kicks in within an hour, and you should see symptom reduction the same day.
Small daily stressors like being late for work typically don’t cause you to break out. Otherwise you’d see a bunch of rash ridden people running around. People generally get stress hives from events like:
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.

What we do know: hives, also known as urticaria, can appear anywhere on the body, including your face, torso, arms, legs, and even inside your mouth and ears. They may range in size from as tiny as a pencil tip to as large as a dinner plate. Hives typically crop up when you have an allergic reaction to a substance—pet dander, pollen, latex—triggering your body to release histamine and other chemicals into your blood. That’s what causes the itching, swelling, and other symptoms.

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.
Hives (medically known as urticaria) appear on the skin as wheals that are red, very itchy, smoothly elevated areas of skin often with a blanched center. They appear in varying shapes and sizes, from a few millimeters to several centimeters in diameter anywhere on the body.

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.

Acute hives can appear at any age, but they are most commonly seen in young adults. The rash has very itchy red areas with white raised central circles that resemble mosquito bites. If the welts grow very large, spreading and joining together or swelling downward deep into body tissue, then they are known as giant hives or angioedema. Angioedema is painful and unsightly, but it is not as itchy. With angioedema the eruptions become large enough to cause swelling of the eyelids, tongue, mouth, hands or feet. In severe cases, hives can be accompanied by other symptoms such as difficulty in breathing, difficulty swallowing, digestive upsets and fever. Hives can occur internally to produce swelling of internal organs. .
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.
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.
Methods of stress relief may include taking a much-deserved vacation, starting a hobby as a distraction from stress, practicing meditation and mindfulness, and exercising. If stress-relieving activities don’t help to reduce your hives, treatment with oral antihistamines will likely help. You can also work with your doctor or a psychologist to address specific causes of stress and develop coping mechanisms.
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.
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.

a vascular reaction of the skin that is commonly immunologically based or may be due to direct exposure to a chemical. Marked by transient appearance of slightly elevated patches (wheals) which are redder or paler than the surrounding skin and often attended by severe itching; called also hives. The wheals may be in very large numbers, mostly over the body, 0.5 to 2 inches in diameter and there is no discontinuity of the epithelium. Called also nettle rash.
“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 a result of itching and scratching the existing ones.”

Urticaria (chronic, acute, or both) affects 15-25% of the population at some time in their lives. [22] The incidence of acute urticaria is higher in people with atopy, [22] and the condition occurs most commonly in children and young adults. [23]

Urticaria typically looks like a raised rash that may be a normal skin colour or pinkish or red in colour. The rash may occur anywhere on the body and often starts off as small round spots that quickly enlarge and spread.
Chronic urticaria is estimated to affect between 0·1–3% of children in the United Kingdom [1]. Physical factors, such as pressure and cold, are the most common identifiable trigger and children with chronic urticaria usually also have angioedema. Approximately 30% of children with chronic urticaria have a positive ASST [39] and approximately 4% have positive thyroid peroxidase antibodies. It is suggested that thyroid function be monitored in children with chronic urticaria and positive thyroid autoantibodies, even though it has not been well established that treatment of clinical thyroid disease, if it develops, will improve the urticaria [65]. It has also been reported that children with severe chronic urticaria have a higher incidence of coeliac disease than controls [66].
If your reaction is severe, especially if the swelling involves your throat, you may need an emergency shot of epinephrine (adrenaline) or steroids. Hives in the throat can block your airway, making it difficult to breathe.

For some, the culprit is obvious—they’ll eat a peanut butter cookie, for example, and immediately break out in a rash. For others, it’s not so cut and dry; symptoms can take several hours to develop. Either way, make an appointment with your doctor if you suspect you have a food allergy. Dr. Jaliman says you’ll likely be put on an elimination diet where you reintroduce one potentially triggering food every week. “Let’s say you’re not eating any of the hives foods and then you add back shellfish and you get the hives again. Then you can pretty much figure it out,” Dr. Jaliman says. After you determine the culprit, nix it from your diet to prevent mild symptoms from becoming chronic. Dr. Jaliman says you’ll likely be prescribed an EpiPen—if you accidentally ingest a trigger food, you could get hives in your throat, which can be dangerous. 
Hives are very common. They usually go away on their own, but if you have a serious case, you might need medicine or a shot. In rare cases, hives can cause a dangerous swelling in your airways, making it hard to breathe – which is a medical emergency.
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.
Hives usually cause itching, but may also burn or sting. They can appear anywhere on the body, including the face, lips, tongue, throat, or ears. Hives vary in size (from a pencil eraser to a dinner plate), and may join together to form larger areas known as plaques. They can last for hours, or up to one day before fading. Read more about hives (urticaria and angioedema).
Keeping a daily food diary will help you pinpoint what foods are causing an adverse reaction and resulting in an attack of hives. Foods that contain large amounts of histamine or increase the release of histamine in the skin cells include shellfish, nuts, eggs, dairy, pineapple, chocolate, wine, and beer. These trigger foods should be completely avoided until you determine what exactly is causing the allergic reaction.
If you tend to break out in hives after eating shellfish, peanuts, tree nuts, eggs, milk, and berries, then you may have a food allergy, says Debra Jaliman, MD, a New York City-based dermatologist and the author of Skin Rules.  
Making a paste of baking soda and water can help to calm hives and also prevent new ones from popping up. Baking soda is known as nahcolite, which is part of the natural mineral natron. Natron contains large amounts of sodium bicarbonate. It has been used since ancient times as a soother and cleanser. Mix a teaspoon of baking soda with some cold water to create a paste and then rub it on the affected area. Let it dry completely before washing it off. You can do this a few times a day, if needed. Relief is typically immediate from this easy hives treatment.
Clinical Context:  Hydroxyzine antagonizes H1 receptors in the periphery. It may suppress histamine activity in the subcortical region of the CNS. Hydroxyzine can be used for symptomatic control. The recommended antihistamine for pregnant patients is diphenhydramine. Hydroxyzine has been used safely in children.

“angioedema urticaria urticarial rashes”

Acute urticaria caused by SIgE against food protein antigens is often identified easily by the patient, particularly as there may be oral symptoms as the food is eaten and as repeated exposure to the foodstuff may lead to progressively more severe reactions, with angioedema and systemic symptoms [2,3]. However, it may be more difficult to identify the causative antigen if this is a contaminant in the food, such as a mould [4] or storage mite [5], or if there is an unexpected ingredient in the foodstuff and a detailed list of ingredients is lacking.
Today, more research is being conducted on the connections between urticaria and stress. For example, some research is focusing on the relationship between stressful life events and the onset or exacerbation of chronic idiopathic urticaria; others are looking at ways to improve chronic urticaria using hypnosis and relaxation techniques. And new research is even looking at the relationship between post-traumatic stress disorder and the incidence and severity of chronic idiopathic urticaria.
Acute hives can appear at any age, but they are most commonly seen in young adults. The rash has very itchy red with white raised central circles that resemble mosquito bites.

In severe cases, hives can be accompanied by other symptoms such as difficulty in breathing, difficulty swallowing, digestive upsets and fever. Hives can occur internally to produce swelling of internal organs. .
Mix a baking soda paste. Baking soda can be used to help relieve the itching of your hives. Mix 1 tbsp of baking soda with enough water to make a paste. Try a few drops at first and stir, adding more as needed. Using your fingers or soft spatula, spread the paste over the hives. Use as often as needed and rinse off with cool water.
Urticaria that develops after exposure to high ambient temperatures (e.g., after exercise, a warm shower or bath, or during a fever). The hives that develop are typically small (1 to 3 mm) and are often surrounded by erythema. Synonym: generalized heat urticaria
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]
Chronic hives should be evaluated by an allergist, who will ask about your and your family’s medical history, substances to which you are exposed at home and at work, exposure to pets or other animals and any medications you’ve taken recently. If you have been keeping a food diary, show it to your allergist.
Urticaria is also known as ‘nettle rash’ or ‘hives’. This condition consists of wheals – spots or patches of raised red or white skin – each of which usually clears away in a few hours to be replaced by other fresh wheals. Urticaria is very common and affects one in five people at some point in their lives.  The more common type of urticaria rash (hives) lasts up to 24 hours, produces larger wheals and may not completely clear for several days.  It sometimes occurs together with swelling of various parts of the body (angioedema) – typically the face, hands and feet, although anywhere may be affected.
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]
Physical urticaria (for example, heat hives) is a type of chronic urticaria produced by physical stimuli. Common environmental provocations such as sunlight, water, cold, heat, exercise, and pressure occasionally induce hives. Dermographism, which literally means “skin writing,” is a common cause of physical urticaria. This is an exaggerated form of what happens to anyone when their skin is scratched or rubbed; a red welt appears at the site of the scratch. In dermographism, raised, itchy red welts with adjacent flares appear wherever the skin is scratched or where belts and other articles of clothing rub against the skin, causing mast cells to leak histamine.

Fortunately, it’s easy to find out whether cold is one of your triggers: Your doctor can administer a simple test that involves placing an ice cube on your skin for five minutes to see if a reaction occurs. If it turns out that cold is a trigger for you, your doctor will recommend that you protect your skin from the cold and take your medications as prescribed.
The cause of chronic hives can rarely be determined.[28] In some cases regular extensive allergy testing over a long period of time is requested in hopes of getting new insight.[29][30] No evidence shows regular allergy testing results in identification of a problem or relief for people with chronic hives.[29][30] Regular allergy testing for people with chronic hives is not recommended.[28]
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.

Cold-induced Urticaria is a disorder in which hives occur within minutes of being exposed to the cold or appear as a result of the effects of warming. Total body exposure to cold, such as swimming in frigid water can result in a drop in blood pressure, fainting, shock and drowning.
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.
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.

There are many causes of hives including foods, drugs, infections, and diseases. Oddly enough, even though there are many potential causes, in the majority of cases of hives, the cause is unknown. Hives causes can be broken down into 3 broad groups:
Solar urticaria is a rare disorder in which urticaria develops on areas of the body which are exposed to sunlight. Itching and urticaria may develop within a few minutes and may progress to angioedema. The symptoms usually resolve in a few hours. (Polymorphic light eruption may also cause an itchy rash on sun-exposed skin, but this rash is papular or eczematous; usually starts 6–8 h after sun exposure and lasts for several days.) Very rarely, patients may develop ‘aquagenic’ urticaria where their skin has been in contact with water (irrespective of its temperature) or urticaria in response to vibration.
Angioedema is a similar skin issue to hives, but it usually last longer than hives. Swelling is under the skin instead of on the surface. With angioedema, a person typically has deep swelling around the eyes and lips and, sometimes, of the genitals, hands and feet. In rare cases, angioedema of the throat, tongue, or lungs can block the airways, making it hard to breathe. This can be life threatening. (23)
Angioedema is a in which small blood vessels leak fluid into the tissues, causing swelling. There is no known cure, but it may be possible to prevent the swelling with medications or occasionally diet. Allergy is a very rare cause of angioedema.
The most common causes of hives are an allergic reaction to certain medications such as antibiotics or codeine ingestion of foods like shellfish chocolate or berries or contact with pollen and cat dander.
Hives are patches of puffy, red, itchy or inflamed skin also known as urticaria, and they can be caused or worsened by significant stress in your life. In fact, stress is one of the most common causes of acute hives (hives that last less than six weeks), along with infectious causes and allergies. Stress has also been known to worsen chronic hives (hives that last more than six weeks), even when the chronic hives are primarily due to another cause.
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]
Clinical Context:  Hydroxychloroquine is the preferred antimalarial agent because of its low toxicity and high effectiveness profile. It is usually well tolerated if carefully monitored by the prescribing physician. Therapy is required for 4-8 weeks before evaluating effectiveness.
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.
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.
In persons with autoimmune hives, the IgG autoantibody that binds to the Fc-receptor tricks the mast cell into believing that the IgE on its surface has encountered an allergen. When this happens, hives or tissue swelling can result. (The diagram above shows a Mast cell with purple histamine granules. The “patient IgG” is the autoantibody that binds to the Fc-receptor.)
Physical urticaria are hives caused by direct physical stimulation of the skin — for example, cold, heat, sunlight, vibration, pressure, sweating, and exercise. They usually happen right where the skin was affected and rarely appear anywhere else. Most appear within 1 hour after exposure.
Keeping a daily food diary will help you pinpoint what foods are causing an adverse reaction and resulting in an attack of hives. Foods that contain large amounts of histamine or increase the release of histamine in the skin cells include shellfish, nuts, eggs, dairy, pineapple, chocolate, wine, and beer. These trigger foods should be completely avoided until you determine what exactly is causing the allergic reaction.
Immunotherapy: Allergy shots help only if a person has hives because of what they breathe. These people can be successfully desensitized. Cross reacting proteins from inhalants that are also found in foods can help drop the degree of reactivity to those foods.
If a specific urticarial trigger can be found, then avoiding that trigger is the most sensible course of action, but most often no underlying cause is ever found.  The main focus of treatment is trying to alleviate symptoms while the urticaria slowly “burns” itself out and eventually clears – a process that may take many months or even some years.
