Hives

Trunk of woman's body covered in hives, with close-up of hives

Most hives (urticaria) are an allergic skin reaction that appears as raised, red, itchy bumps of different shapes and sizes. Patches of hives may combine to form raised, reddened skin over large areas of the body. Hives are often minor, but they can also be the first sign of a life-threatening allergic reaction (anaphylaxis) that requires emergency care.
