Knee pain
Knee pain can often be treated at home – you should start to feel better in a few days. See a GP if the pain is very bad or lasts a long time.
How to ease knee pain and swelling
Try these things at first:
- put as little weight as possible on the knee – for example, avoid standing for a long time
- use an ice pack (or bag of frozen peas wrapped in a teatowel) on your knee for up to 20 minutes every 2 to 3 hours
- take paracetamol
See a GP if:
- it doesn't improve within a few weeks
- you can't move your knee or put any weight on it
- your knee locks, painfully clicks or gives way – painless clicking is normal
Go to to a minor injuries unit or A&E if:
- your knee is very painful
- your knee is badly swollen or has changed shape
- you have a very high temperature, feel hot and shivery, and have redness or heat around the knee – this can be a sign of infection
