Swollen arms and hands (oedema)

Swelling in the arms or hands (oedema) can sometimes get better on its own. See a GP if it does not go away, you're worried or if you do not know what's causing it.

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.

This can be caused by:

  • staying in the same position for too long
  • eating too much salty food
  • taking certain medicines, such as some blood pressure medicines, contraceptive pills, antidepressants and steroids
  • cancer treatment
  • an infection or injury, such as a sprain or strain
  • sudden changes in temperature, such as very hot weather
  • an insect bite or sting, or a skin allergy such as angioedema
  • problems with your kidneys, liver or heart
  • a blood clot or circulation problems
  • lymphoedema

Symptoms of oedema in the arms or hands include:

The inside of 2 white arms, from wrist to elbow. 1 arm is swollen, so it looks much bigger and the skin is stretched tight.
