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 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 tea towel) on your knee for up to 20 minutes every 2 to 3 hours
- take painkillers such as paracetamol or ibuprofen
See a GP if:
- knee pain does not improve within a few weeks
Refer yourself for back or joint help
In many areas you may be able to get help, such as physiotherapy, from NHS community musculoskeletal (MSK) services without needing a referral from a GP.
Get advice from 111 now if:
- your knee is very painful
