What Are the Symptoms?
- Raised, whitish or reddish welts of varying size seen on the skin, especially in the waist or armpit areas
- The welts itch intensely, often at night.
- Welts may come and go over minutes or hours.
- Swelling in the deeper layers of the skin around your eyes and lips; your doctor will call this angioedema. It’s less likely, but it can also affect your hands and feet, mucous membranes, or your genitals.
