Angioedema: This is a Type 1 allergic reaction and can be potentially serious. You need to figure out what is the specific cause of the allergy - usually a certain food, sometimes a medication. Best to see an allergist to run allergy profile - then avoidance, desensitization, or meds for flares. Always keep Benadryl (diphenhydramine) (antihistamine) stocked at home and take immediately with hives/swelling.
