HAE symptoms

Recognizing the symptoms of an HAE attack

Hereditary angioedema (HAE) can cause attacks of swelling in any part of the body, but the most common locations include the skin (eg, face, hands, feet, genitals), stomach, and throat. Before an attack, some people with HAE experience early warning signs, also called prodromal symptoms, such as tingling, rash, fatigue, or nausea.
