Hives — also known as urticaria (ur-tih-KAR-e-uh) — is a skin reaction that causes raised, red, itchy welts (wheals, or swellings) in sizes ranging from small spots to large blotches several inches in diameter. Individual welts appear and fade as the reaction runs its course. Angioedema is a related type of swelling that affects deeper layers in your skin, often around your eyes and lips.
In most cases, hives and angioedema are harmless and don't leave any lasting marks, even without treatment. The most common treatment for hives and angioedema is antihistamine medications. Serious angioedema can be life-threatening if swelling causes your throat or tongue to block your airway and leads to loss of consciousness.
