Physical Urticaria

Physical urticaria is a skin condition that causes red, itchy welts or hives when the skin comes into contact with various physical triggers. These triggers can include things like heat, cold, pressure, or friction. In this article, we will provide simple and easy-to-understand explanations of what physical urticaria is, its types, common causes, symptoms, diagnostic tests, treatments, and medications.

Physical urticaria is a skin condition where the skin reacts to physical triggers by developing hives or welts. These hives are red, itchy, and can vary in size and shape. The condition occurs when certain physical stimuli cause the release of histamines in the skin, leading to an allergic reaction.

Types of Physical Urticaria
