Urticaria is the official medical term for hives. The photo depicts the characteristic wheals that occur in urticaria. Common triggers include allergens like insect stings, foods, and certain medications. However, most cases of hives are not allergic, and the underlying cause is unknown. Urticaria flare-ups are highly itchy and temporary. Treatment consists of agents to relieve symptoms until the flare-up resolves.
