Allergic Hives or urticaria, are red, itchy bumps near the surface of the skin. Like many other allergies, they are the result of overproduction of histamine and any reaction can be caused by a wide variety of things. In many cases, skin hives are the consequence of a food allergy. Eggs, peanuts, shellfish, milk and other foods can cause hives. The bumps are not generally painful but the itchiness is uncomfortable and the hives can become worse by scratching.

Although there are number of different treatments available for allergies, most if not all only treat the symptoms and not the root cause of the problem. Well-known antihistamines such as Benadryl a.k.a. diphenhydramine, Claritin also called loratadine together with decongestant sprays such as Nasonex, are available by prescription or over the counter and do a good job in providing relief for allergy sufferers. Allergic reactions are ultimately caused by an overactive immune system and a treatment known as allergy immunotherapy attempts to offer a longer-term solution by changing how the immune system responds to various allergens. It is, in effect, a form of vaccination better known as allergy shots
