Itchy swollen lesions on the skin, often referred to as hives, are known as?

Hives, scientifically referred to as urticaria, present as itchy, swollen lesions on the skin. These lesions are specifically known as wheals. Wheals are characterized by their raised, pale, and often itchy appearance, resulting from an allergic reaction or other stimuli that cause the release of histamines and result in localized swelling.

Chilblains refer to painful inflammation of small blood vessels in the skin that occur when a person is exposed to cold air, and they do not match the description of itchy, swollen lesions associated with hives. Bumps is a general term that could refer to various kinds of skin lesions but lacks the specificity needed to describe hives. Nodules are solid, round, or oval elevated lesions that may develop in the skin or tissue and are typically not associated with the sudden onset and itching characteristic of hives. Thus, wheals is the correct term as it precisely describes the appearance and nature of hives.
