It has been reported that some patients have been misdiagnosed with Parasitic Disease, when in fact the correct diagnosis in their specific case was Angioedema.
Most cases of angioedema resolve in a few days without any treatment, but medication is often prescribed. Antihistamines and oral steroids are used to relive swelling. People with hereditary angioedema can benefit from treatment to prevent attacks. A physical examination as well as examining the welts or swelling can help on diagnosing angioedema. Blood or allergy tests are also often ordered.
