How to ease swelling yourself
Swelling 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
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
do not stay in the same position for long periods of time
do not wear clothes that are too tight
Non-urgent advice: See a GP if your arm or hand is swollen and:
- it has not improved after treating it at home for a few days

Urgent advice: Ask for an urgent GP appointment 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
Immediate action required: Call 999 if:
- you feel short of breath or are struggling to breathe

You could have a blood clot in your lungs, which needs immediate treatment in hospital.
