Hives (or urticaria) are red, itchy, raised areas of the skin that can range in size and appear anywhere on your body. Most common are acute cases, where food or drug allergies are triggers. These hives usually go away within a few days. In cases of chronic hives, people may suffer for months to years.
Angioedema is a swelling of the deeper layers of the skin that sometimes occurs with hives. Angioedema is usually not red or itchy. The areas often involved are the eyelids, lips, tongue, hands and feet.
Food or drug reactions are a common cause of acute hives and/or angioedema. Viral or bacterial infection can also trigger hives in both adults and children. Physical urticaria are hives resulting from a non-allergic source: rubbing of the skin, cold, heat, physical exertion or exercise, pressure and direct exposure to sunlight.
If the cause of your hives can be identified, you should avoid that trigger. With acute hives, some drugs or foods may take days to leave the body, so your allergist may prescribe antihistamines to relieve your symptoms until that happens.
