About Hives. Hives (or urticaria) are red raised bumps or welts on the skin. They can appear anywhere on the body and can look like tiny little spots or large interconnected bumps. Individual hives can last anywhere from a few hours to a week (sometimes longer), and new ones might replace those that fade.
These itchy welts can show up anywhere on your skin. Theyâre caused by an allergic or other type of reaction. Your doctor may call them urticaria. They can last a few minutes or several days before they go away. Sometimes theyâre a sign of more serious problems, especially when you have trouble breathing. Hives that recur or that last more than 6 weeks are considered chronic urticaria and require further evaluation.
