What is another name for hives, characterized by round wheals on the skin?

Urticaria is the medical term used to describe hives, which are characterized by raised, round wheals or welts on the skin that often appear suddenly. These wheals are typically itchy and can vary in size, and they occur as a result of an allergic reaction or other triggers that cause the release of histamines in the body. This release leads to increased blood flow and swelling in the areas affected, creating the distinctive appearance of hives.

The term "urticaria" comes from the Latin word "urtica," meaning nettle, a plant known for causing a stinging sensation when contacted, similar to the itchiness experienced with hives. Understanding this terminology is crucial for healthcare professionals as it helps in accurately diagnosing and treating skin conditions.
