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.
Hives are also known as urticaria, welts, wheals, or nettle rash. It is a red, raised, itchy skin rash that is sometimes triggered by something that produces an allergic reaction-an allergen. When there is an allergic reaction the body releases a protein called histamine. When histamine is released our capillaries (tiny blood vessels) leak fluid.
