Overview 

Urticaria, commonly known as hives, is a skin condition characterized by raised, itchy welts (wheals) that can appear anywhere on the body. These welts may vary in size and shape and often fade within hours but can reappear in different areas.

Urticaria can be acute (short-term) or chronic (long-lasting). It is usually triggered by an allergic reaction or other underlying factors affecting the immune system.
