Overview

Swelling in the arms or hands often goes away on its own. See a GP if it does not get better in a few days.

Common causes of swollen arms and hands

Swelling in the arms and hands is often caused by a build-up of fluid in these areas, called oedema.

Oedema is usually caused by:

  • staying 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

Check if you have oedema

Symptoms of oedema include:

  • Swollen or puffy arms or hands
  • Shiny, stretched or red skin

How to ease swelling yourself

Swelling should go away on its own, but there are some things you can try to help.

Do:

  • 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

Don't:

  • do not stay in the same position for long periods of time
  • do not wear clothes that are too tight

See a GP if your arm or hand is swollen and:

  • it has not improved after treating it at home for a few days
  • it gets worse

Get advice from NHS 111 Wales if available in your area or 0845 46 47 now if:

  • the swelling is only in 1 arm or hand 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

Call 999 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, which needs immediate treatment in hospital.

Treatment for swelling and oedema

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

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