Angioedema is an allergic reaction. It causes swelling and welts in the deep layers of the skin. Angioedema can sometimes occur along with hives. Hives are an allergic reaction in the outer layers of the skin. Angioedema can range from mild to severe. Painful welts can develop on the face. Angioedema can also occur on other parts of the body. In severe cases, the inside of the throat can swell and make it hard to breathe.
Many things can cause this condition, including foods, insect bites, and medicines (such as aspirin and some blood pressure medicines). It also can run in families. Sometimes you may know what caused the reaction, but other times you may not know.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
