A. Hives (urticaria) are raised, red spots on the skin that often itch. Hives are usually indicative of an allergic reaction. Hives are a common reaction in people who have allergies. A number of substances can trigger an outbreak of hives, including foods, medications, pollen, animal dander, or insect bites. Hives can also develop as a result of sun or cold exposure, infections, excessive perspiration, and emotional stress. The reason why stress seems to precipitate an outbreak of hives in many people is not completely understood but is likely related to the known effects of stress on the immune system.
