What Is The Medical Term for a Rash of Itchy Wheals (Hives)?
The medical term for a rash of itchy wheals (hives) is urticaria. Urticaria is characterized by the formation of red, raised skin lesions called wheals (or weals), often accompanied by itching. The wheels are usually smaller than a centimeter in diameter and may vary in number from a few to hundreds. Wheals may be flat or raised above the surface of the skin, but they do not contain pus.
Hives can occur anywhere on the body but are most common on the neck, upper trunk, and arms. Hives also may affect the face, ears, lips, and tongue. Hives that occur on the lower extremities are rare; however, they can occur at sites where there has been trauma to blood vessels in those areas (such as bony prominences).
The cause of most cases of urticaria is unknown; however, some cases occur as a result of allergies or infections. In rare cases, hives can be caused by medications or food poisoning.
