Urticaria

Summary of Urticaria
Urticaria, commonly referred to as hives, is a kind of skin rash notable for pale red, raised, itchy bumps. Urticaria may cause a burning or stinging sensation. Lesions are frequently caused by allergic reactions; however, there are many nonallergic causes. Most cases of hives lasting less than six weeks (acute urticaria) are the result of an allergic trigger. Chronic urticaria (hives lasting longer than six weeks) is rarely due to an allergy.
