Angioedema Definition and Symptoms
Angioedema is a skin reaction that is similar to hives and affects very deep layers of the skin. The most common places it affects are around the eyes, cheecks, or lips. Things that can trigger an angioedema attack are foods, medications, environmental factors, or underlying medical conditions. Symptoms include thick, firm welts, swelling, redness, pain, and warmth in the affected areas.
