Definition

Angioedema is a common condition that involves swelling beneath the surface of the skin with or without redness. Angioedema can occur around the eyelids and lips, or on the face, hands, feet, or genitalia. Since this condition can cause swelling of the airways, it is important that you seek medical care if you think you have angioedema.
