Angioedema: frightening and frustrating.

Where this comes from

Abstract

Angioedema can have a variety of causes, including drug reactions, food allergies, and C1 esterase inhibitor deficiency, but many cases are idiopathic. Swelling usually subsides in days if the offending agent can be removed. The throat is often involved, but few patients actually require intubation.
