I'm having my knee x -rayed as it's still going stiff after a run. It's not getting worse though, I couldn't even run 2 months ago and was limping about. All down to a quad strain (I'm hoping). Although the doc said it could be cartilage wearing down and reminded me of my age, hmm! (I'm 40 something)!
Anyway, my main worry was, 'Can I still run??? 'Yes, was the answer.'
I sighed with relief, then after thought I really have been bitten by the running bug!!
