Chronic Urticaria, also called chronic hives, is a skin condition where red, itchy welts appear on the body and last for more than six weeks. These hives may come and go, vary in size, and change locations. The condition can last for months or even years and may happen without a clear reason.

- Physical factors like pressure, heat, cold, or sunlight
