What is Urticaria

Urticaria (also known as hives) is a disease characterized by the sudden development of itchy pale red bumps (wheals, hives) on the skin. Wheals may present in variable sizes and shapes and have a fleeting nature, with the skin returning to its normal appearance in around 24 hours. These wheals may appear in certain parts of the body, or they may be generalized. Hives are often accompanied by swelling known as angioedema.
