The main symptom of angioedema is swelling that develops below the skin’s surface.
Swollen skin
Swelling caused by angioedema can develop suddenly or come on gradually over a few hours. It normally lasts a few days.
The swelling most often affects the:
- hands
- feet
- area around the eyes
- lips and tongue
- genitals
In severe cases, the inside of the throat or bowel can be affected.
Rash
Often, the swelling occurs with a raised, itchy rash called urticaria (hives). The rash will usually settle in a few days. Otherwise, the skin over the swelling may feel tight and painful but look normal.
Other symptoms
Less common symptoms of angioedema include:
- difficulty breathing
- red, irritated eyes (conjunctivitis)
- tummy (abdominal) pain
- feeling sick
- diarrhoea
- dizziness
- fainting
If you experience any of these symptoms, especially if you have difficulty breathing, seek medical attention immediately.
