Hives, also called urticaria, are raised, red, itchy welts that can appear suddenly on any part of the body. These welts can vary in size, and while they may fade in one area, they often reappear elsewhere on the skin. Hives can be triggered by allergies, but they also have other causes, such as viral infections, certain medications like codeine and morphine, and physical factors such as heat, cold, pressure, or scratching.

Chronic urticaria, which persists for months or even years, is usually not linked to an external allergy. Instead, it is often an autoimmune condition. Our specialists at Snö Asthma & Allergy are highly experienced in treating both acute and chronic hives with effective medications, helping patients manage this frustrating condition.
