Knee pain can often be treated at home. You should start to feel better in a few days. Call 111 if the pain is very bad.
How to ease knee pain and swelling
If you have knee pain, try these things at first:
- put as little weight as possible on your knee – for example, avoid standing for a long time
- use an ice pack or bag of frozen peas wrapped in a tea towel on your knee for up to 20 minutes every 2 to 3 hours
- use painkillers such as paracetamol or ibuprofen gel or tablets
Non-urgent advice: See a GP if:
- knee pain does not improve within a few weeks
Urgent advice: Get advice from 111 now if:
- your knee is very painful
- you cannot move your knee or put any weight on it
- your knee is badly swollen or has changed shape
- your knee locks, gives way or painfully clicks – painless clicking is normal
- you have a very high temperature, feel hot and shivery, and have redness or heat around your knee – this can be a sign of infection
111 will tell you what to do. They can tell you the right place to get help if you need to see someone.

Other ways to get help

They're also called walk-in centres or minor injuries units.
You may be seen quicker than you would at A&E.
