Knee Pain

*Don't compensate, ride less.

Saddle back (saddle down), gear down. That - and the below stretches - helped me at least.

(*seek professional help).

I also get knee pain . left knee , behind knee cap and above . quickly scanned the other posts. I am left footed so i maybe using my left leg more. mind you after fifty odd miles both hurt. any more mileage they hurt for a few days .

anterior knee pain?

i have just the solution for *you! stand up leaning every so slightly forward, so the majority of your weight in on the balls of your feet. tense your quads, which should force your knees backwards. once balanced, repeat in short sharp pulses.
once used to the feeling it's probably easier to do whilst sat up in bed or across a sofa.

(*it worked for me, no idea if it will help you)

sit up on your bed, legs straight, toes casually pointing forward. now try point your heels forward. that's the sort of thing you want to be doing. (i don't know if this is the right term...it's like gently hyperextending your knee backwards.)
