Hives, also known as urticaria, are itchy, raised welts that can appear on the skin as a result of an allergic reaction, environmental factors, or an underlying medical condition. They can vary in size, shape, and color, and can appear anywhere on the body. The asthma and allergies center in Maryland helps educate patients about hives to keep them informed about the condition. 

In this article, we will explore the types, causes, symptoms, diagnosis, treatment, and prevention of hives.
