Definition

Angioedema is a swelling, similar to hives, but the swelling is beneath the skin rather than on the surface. The hives are called welts. It is also possible to have angioedema without hives.

Symptoms

The main symptom is the sudden development of swelling. You may also develop welts.

The welts usually occur around the eyes and lips. They may also be found on the hands, feet, and throat. They may form a line or be more spread out.

The welts are painful and may be itchy. They turn pale and swell if irritated.

Other symptoms may include:

Abdominal cramping
Breathing difficulty
Swollen eyes and mouth
Swollen lining of the eyes (chemosis)
