Urticaria, also known as hives, is an outbreak of pale red bumps or welts on the skin that appear suddenly. The swelling that often comes with hives is called angioedema. Allergic reactions, chemicals in certain foods, insect stings, sunlight, and medications can cause hives.
Urticaria is a skin disorder manifesting in wheals in 30% to 40%, angioedema in 10% to 20%, or both in one third of cases. Urticaria is defined as “inducible” when wheals are induced by a known trigger and as “chronic spontaneous urticaria” (CSU) when the trigger is unidentified.
