Swelling in the ankles, feet or legs often goes away on its own. See a GP if it does not get better in a few days.
Swelling in the ankles, feet and legs is often caused by a build-up of fluid in these areas, called oedema.
Oedema is usually caused by:
- standing or sitting in the same position for too long
- eating too much salty food
- being overweight
- being pregnant
- taking certain medicines – such as some blood pressure medicines, contraceptive pills, hormone therapy, antidepressants or steroids
Oedema can also be caused by:
- an injury – such as a strain or sprain
- an insect bite or sting
- problems with your kidneys, liver or heart
- a blood clot
- an infection
