A raised, itchy rash (hives) is a common symptom of angioedema. It often affects the lips, tongue and eyelids, hands, feet and genitals.
Treatments for angioedema include trying to identify the underlying cause and avoiding it, and medicines like antihistamines and steroid tablets.
Types of angioedema include allergic and non-allergic angioedema, idiopathic angioedema (where the cause is unknown) and hereditary angioedema.
Angioedema is sudden swelling that's often caused by an allergic reaction. It can be serious if your throat swells up and it affects your breathing.
