Urticaria (Hives)

Urticaria (Hives)

Urticaria (hives) are localized, pale, itchy, pink wheals (swellings) that can burn or sting. They may occur singularly or in groups on any part of the skin. They are part of an allergic reaction and are very common. Allergic reactions, chemicals in foods, or medications may cause hives; sometimes it is impossible to find out the cause. Antihistamines are prescribed to provide relief and work best if taken on a regular schedule to prevent hives from forming.
