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

It's usually caused by:

It can also be caused by:
- an injury – such as a strain or sprain
- sudden changes in temperature – such as very hot weather
- an insect bite or sting
- a skin allergy such as angioedema
- problems with your kidneys, liver or heart
- a blood clot
- an infection

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

get some gentle exercise, like walking, to improve your blood flow
drink plenty of water
wash, dry and moisturise your arms or hands to avoid infections
put your hands in a bath of warm water and then cold water to help move the fluid away from the area
