What is swollen ankles, feet and legs?
Swelling in the ankles, feet, and legs (oedema) is common and is often caused by standing or sitting for too long, being overweight, pregnancy, or injury. It can also be a sign of a more serious condition if it happens suddenly or is only on one side.
When NHS resources suggest seeing a GP
- Swelling has not improved after a few days
- Only one leg is swollen (could be DVT)
- Swelling is severe or gets worse
- You have breathlessness with the swelling
Self-care information from NHS
- Elevate your legs when resting
- Take regular walks
- Wear comfortable shoes
- Reduce salt intake
Common questions
When is ankle swelling an emergency?
Seek urgent help if one leg is suddenly swollen, warm, and painful (possible DVT), or if swelling comes with chest pain or difficulty breathing (possible heart or kidney problem).
Why are my ankles swollen at the end of the day?
Gravity causes fluid to pool in the legs when standing or sitting for long periods. Elevating the legs and walking regularly helps.
