What are hives also referred to as?

Hives are referred to as wheals, which are raised, itchy areas on the skin that can vary in size and shape. Wheals are typically a result of an allergic reaction, leading to localized swelling due to an accumulation of fluid in the dermis, the lower layer of skin. This term is specifically used to describe the appearance of hives and is a precise term in dermatology.

The other terms represent different skin conditions: vesicles are small fluid-filled blisters, abscesses refer to localized infections that produce pus, and comedones are the medical term for blackheads or whiteheads, which are related to acne. Thus, the term "wheals" accurately describes the phenomenon of hives.
