The Asthma and Allergy Foundation of America (AAFA), a not-for-profit organization founded in 1953, is the leading patient organization for people with asthma and allergies, and the oldest asthma and allergy patient group in the world.
Hives (AKA urticaria) is not contagious by any means. They are a skin disorder that results in red, sometimes itching patches of raised skin. The patches of skin can be small or large, and generally appear quite fast and disappear on their own within hours or days. They can be as small as a few millimeters and as large as inches, and can even join together to become large areas called plaques. When they join together all over your body, they are generally known as body hives. This form of rash is often quite itchy in nature and can burn. Learn more on our page title “Are Hives Contagious?”
The Vasculitis Foundation is pleased to announce its Dream Big! campaign. The aim of this year-long campaign is to fast track the advances about which every person impacted by vasculitis is dreaming: faster diagnosis; better, less invasive treatments; and, ultimately, a cure for all forms of the disease.

Cases of urticaria and angioedema can be acute, lasting less than 6 weeks, or chronic, lasting more than 6 weeks. The length of symptoms can often be a clue as to the cause of the symptoms. For example, the most common cause of acute urticaria and angioedema in children is viral infections.

Cold-induced urticaria: Urticaria occurs after exposure to cold, cold objects or cold water. The urticaria is usually localised to exposed areas but sudden total body exposure, as in swimming, may cause a drop in blood pressure and can rarely be fatal.
Urticaria (hives) is a vascular reaction of the skin marked by the transient appearance of smooth, slightly elevated papules or plaques (wheals) that are erythematous and that are often attended by severe pruritus. Individual lesions resolve without scarring in several hours. Most cases of urticaria are self-limited and of short duration; the eruption rarely lasts more than several days, it but may be recurrent over weeks. Chronic urticaria is defined as urticaria with recurrent episodes lasting longer than 6 weeks).
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 “chronic” in CIU means that symptoms last six weeks or more. CIU is an unpredictable form of chronic hives that can appear at any time with no identifiable cause. These hives may not go away for many months—or even years. CIU can be difficult to diagnose.
The prognosis in acute urticaria is excellent, with most cases resolving within days. Acute urticaria usually can be controlled using only symptomatic treatment with antihistamines. If a known triggering factor is present, avoidance is the most effective therapy. Acute urticaria causes discomfort, but it does not cause mortality, unless it is associated with angioedema involving the upper airways. [25, 26, 27] If a patient continues to be exposed to a known trigger, the condition may become chronic.
Urticaria, commonly referred to as hives, is the most frequent dermatologic disorder seen in the emergency department (ED). It appears as raised, well-circumscribed areas of erythema and edema involving the dermis and epidermis that are very pruritic. Urticaria may be acute (lasting <6 wk) or chronic (lasting >6 wk). A large variety of urticaria variants exist, including acute immunoglobulin E (IgE)–mediated urticaria, chemical-induced urticaria (non-IgE-mediated), autoimmune urticaria, cholinergic urticaria, cold urticaria, mastocytosis, periodic fever syndromes including Muckle-Wells syndrome, and many others. [2, 10] While acute urticaria is generally related to an exogenous allergen or acute infection, chronic urticaria is more likely to be associated with autoimmunity. [8, 11, 12]
Urticaria predominantly affects adult females and up to 20% of the population sometime in their life.  It presents as a diffusely raised itchy wheal and flare reaction which migrates over the skin surface. All forms of Urticaria may occur in association with deeper skin swelling or angioedema and equally, angioedema may occur in isolation with no apparent urticaria (when Hereditary Angioedema (HAE) due to a deficiency of the C1 Esterase inhibitor enzyme should be suspected).
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].
Pityriasis rosea typically fades without treatment in six to eight weeks. During this time, you can use an OTC anti-itch medication, like diphenhydramine (Benadryl) or cetirizine (Zyrtec) to ease your symptoms.
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.
Allergic reactions to foods such as nuts, seafood (including fish), chocolate, berries and milk common causes of ordinary hives. Viral infections, insect bites and medications can also cause ordinary hives.
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.
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.
It is typically diagnosed when chronic hives do not appear to be associated with any other systemic disease process, and are not due to one of the physically induced urticarias. Research during the past decade suggests an association with autoimmunity in 35-45% of patients. When severe, it can be resistant to therapy and there is a 40% incidence of accompanying angioedema. Angioedema may involve the face, lips, tongue, throat, or extremities but not the larynx. The remission rate is 65% within three years, 85% within five years and 98% within ten years. A form of angioedema in the absence of hives with no identifiable cause is termed idiopathic 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.
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 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.
Many different drugs may cause urticaria. The cyclo-oxygenase (COX)-inhibitor drugs such as aspirin [22] and NSAIDs [23] are a common cause. Opiates, including codeine, may trigger direct histamine release from mast cells [24]. Many different over-the-counter analgesics contain aspirin, NSAIDs and/or codeine and it is therefore important to be specific as to exactly which painkillers patients may or may not be able to take. These reactions are not IgE-mediated and specific IgE testing for aspirin, NSAIDs and opiates is not indicated. Evidence of oxidative damage, as shown by increased protein carbonylation and lipid peroxidation, and of increased anti-oxidant enzyme activity has been found in patients who develop non-IgE-mediated drug-related urticaria [25]; however, it is not known if this oxidative stress is the cause or the effect of the reaction. [Drugs such as angiotensin converting enzyme inhibitors (ACEI) and statins cause isolated angioedema much more commonly than urticaria]. Radio-contrast media and plasma substitutes may also cause urticarial reactions.

Other medical conditions that can cause pruritus (usually without rash), such as diabetes mellitus, chronic renal insufficiency, primary biliary cirrhosis, or other nonurticarial dermatologic disorders
Try vinegar. There are many healing nutrients in vinegar. Pick any kind of vinegar. Pour 1 tsp of vinegar into 1 tbsp of water and stir. Using a cotton ball or napkin, apply the mixture to your hives. This will help soothe the itching.[11]
Hives, also known as urticaria, is a kind of skin rash with red, raised, itchy bumps.[1] They may also burn or sting.[2] Often the patches of rash move around.[2] Typically they last a few days and do not leave any long-lasting skin changes.[2] Fewer than 5% of cases last for more than six weeks.[2] The condition frequently recurs.[2]
Rubbing or scratching (simple dermographism). This is the most frequent cause of physical urticaria. Symptoms appear within a few minutes in the place that was rubbed or scratched and typically last less than an hour.
Question on Papular Urticaria: Is Urticaria & Papuller Urticaria the same? My 15 yr old sis is suffering from Papullar Urticaria since 2 yrs. We tried all medication including Allopathic (also Steroids), homeopathy. But no improvement. Pls suggest a remed
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 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.
The main symptom of urticaria is a red, raised skin rash. They can appear anywhere on the body, including the face, hands, lips, tongue, throat or ears. Hives vary in size (from a pencil rubber to a dinner plate), and may join together to form larger areas known as plaques.

  1. Use a cold compress. Since skin irritation is the main symptom of hives, you should treat the skin to help alleviate the hives. Take a clean, cotton towel and soak it in cool water. Squeeze out the extra water and place over the affected areas. Leave it on for 10 minutes, then re-soak the towel to keep the water cool, which will in turn keep your skin cool.
    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.
    Angioedema is different. The swelling happens under the skin, not on the surface. It’s marked by deep swelling around the eyes and lips and sometimes of the genitals, hands, and feet. It generally lasts longer than hives, but the swelling usually goes away in less than 24 hours. It’s rare, but angioedema of the throat, tongue, or lungs can block your airways, making it hard to breathe.
    Chronic hives can lead to severe discomfort, distress, and possibly depression. Stress, too, can aggravate hives, creating a vicious cycle. Patients who experience symptoms of depression should speak to a doctor.
