Urticaria, also commonly called hives, involves a histamine-mediated response that can be either acute or chronic. A wide range of situations are associated with hives, including a variety of infections, allergies to foods and medications, or underlying systemic disease. Urticaria are pink or red wheals that are very pruritic. Frequently they are associated with anaphylaxis and/or angioedema.
