Swollen ankles, feet and legs (oedema)

Swelling in the ankles, feet or legs often goes away on its own. Talk to your GP if it doesn't get better in a few days.

Causes of swollen ankles, feet and legs

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, 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

How to ease swelling yourself

Swelling in your ankles, feet or legs should go away on its own. But there are some things you can try to help.


  • lie down and use pillows to raise the swollen area when you can

  • get some gentle exercise, like walking, to improve your blood flow

  • wear wide, comfortable shoes with a low heel and soft sole

  • wash, dry and moisturise your feet to avoid infections


  • do not stand or sit for long periods

  • do not wear clothes, socks or shoes that are too tight

Non-urgent advice: Talk to your GP if your ankle, foot or leg is swollen and:

  • the swelling is only in 1 ankle, foot or leg and there's no obvious cause, such as an injury
  • the swelling is severe, painful or starts very suddenly
  • the swollen area is red or feels hot to the touch
  • your temperature is very high, or you feel hot and shivery
  • you have diabetes
  • it has not improved after treating it at home for a few days
  • it gets worse

Immediate action required: Call 999 or 112 or go to your nearest ED if:

  • you feel short of breath or are struggling to breathe
  • your chest feels tight, heavy or painful

You could have a blood clot in your lungs. This needs immediate treatment in the hospital.

Treating swelling and oedema

Treatment for swelling or oedema that does not go away on its own depends on the cause.

It may include lifestyle changes, such as losing weight or going on a low-salt diet.
