Hives Hives are raised, often itchy, red bumps (welts) on the surface of the skin. They are usually an allergic reaction to food or medicine. They can also appear without cause. When you have an allergic reaction to a substance, your body releases histamine and other chemicals into the blood. This causes itching, swelling, and other symptoms. Hives are a common reaction. Persons with other allergies, such as hay fever, often get hives. When swelling or welts occur around the face, especially the lips and eyes, it is called angioedema.

- Hives are raised areas of the skin that itch intensely and are red with a pale center (picture 1). Hives are a very common condition. About 20 percent of people have hives at some time during their lives. Hives develop when there is a reaction that activates immune cells in the skin called mast cells. When activated, these cells release natural chemicals. One important chemical is histamine, which causes itching, redness, and swelling of the skin in an area: a hive.
