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

  • move your whole arm and shoulder

  • try raising your hand above your head while you open and close your fist

  • massage your arm or hand towards your body using firm but not painful pressure – for example, start at your fingertips and massage towards your palm

  • 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

Don’t

  • do not stay in the same position for long periods of time

  • treating any condition that is causing the swelling
