What is the common name for urticaria?

Urticaria is commonly known as hives. This term is used to describe a skin condition characterized by the appearance of raised, itchy welts on the skin. Hives can occur due to various factors, including allergic reactions, stress, infections, or other triggers that cause the release of histamines in the body. The welts typically vary in size and can appear anywhere on the body, often accompanied by itching or a burning sensation.

The other terms listed do not accurately describe urticaria. A rash is a general term that refers to any visible skin condition or irritation but does not specifically denote hives. Eczema refers to a chronic inflammatory skin condition that causes patches of skin to become inflamed, itchy, and red. Psoriasis is a chronic autoimmune condition that leads to the rapid growth of skin cells, forming scales and red patches that can be itchy or painful. Each of these conditions has distinct characteristics and would not be synonymous with urticaria.
