Understanding Urticaria and its Types

Urticaria, characterized by itchy wheels that disappear and reappear on the body, comes in two forms - acute and chronic. Acute Urticaria lasts less than six weeks and is common, affecting about one in five people, while chronic Urticaria, lasting longer than six weeks, is rare and seen in about one in four Acute Urticaria patients. Chronic spontaneous Urticaria, a subtype of chronic Urticaria, constitutes about 75% of cases and is associated with angioedema, a deeper swelling that's non-itchy and takes longer to disappear.
