Hives (urticaria)

Hives, also known as urticaria, is a kind of skin rash with red or flesh-colored, raised, itchy bumps. Hives may burn or sting. The patches of rash may appear on different body parts, with variable duration from minutes to days, and typically do not leave any long-lasting skin change. Fewer than 5% of cases last for more than six weeks. The condition frequently recurs.
