Postpartum hives or urticaria are itchy, red, or skin-colored rashes on the skin. These occur when the body’s immune system comes in contact with allergens and produces histamine (from small capillaries) and other chemicals into the blood. The histamine, in turn, bloats the blood vessels, releasing plasma into the skin. This fluid collects in the skin and causes inflammation and itchy rashes on its surface (1). Hives are also called weals, nettle rash, and welts and are commonly seen on arms, back, and feet (2).
