When to see a doctor for knee pain
When to see a doctor for knee pain depends on the signs. Go to urgent care or see a doctor the same day if:
- the knee is very painful, or you cannot move it or put weight on it
- it is badly swollen or has changed shape
- it locks, gives way, or painfully clicks (painless clicking is normal)
- you have a high temperature, or feel hot, cold or shivery, with redness or heat around the knee, which can signal infection.[1]
Book a GP or physiotherapist
Do this if the knee hasn't improved within a few weeks,[1] if there was a significant impact, or if the pain keeps you from walking.[3]
No device, session or home remedy should delay any of the above.
