Knee pain
Knee pain can often be treated at home. You should start to feel better in a few days. Call 811 if the pain is very bad.
How to ease knee pain and swelling
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 painkiller such as paracetamol or ibuprofen gel (or ibuprofen tablets if needed)
Non-urgent advice:See a GP if:
- knee pain does not improve within a few weeks
- your knee locks, painfully clicks or gives way – painless clicking is normal
Urgent advice:Get advice from 811 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
- 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
811 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
You can also go to an urgent treatment centre if you need to see someone now.
They’re also called walk-in centres or minor injuries units.
You may be seen quicker than you would at A&E.
Treatment from a GP
A doctor can suggest treatment based on what’s causing your knee pain.
They might:
- prescribe medicine or physiotherapy
- refer you to hospital for a scan or specialist treatment (for example, surgery)
