For the last 4 days I've woken up with a stiff knee. Started as a tightness on the outer upper right knee. Only painful to walk or bend.
Managed to gently walk/stretch it back to almost normal first day.
Now it's moved to the outside of the knee and I can barely move it without pain.
Strangely it doesn't hurt at all when cycling. I've been a lot less active than normal and can't think what else has changed.
Apologies for the word salad. Any ideas greatly appreciated.
