I have been having a lot of pain on the inside (medial) of my left knee. The funny thing is, it feels OK when I ride, but afterwards it hurts to stand up, walk, or straighten the leg. Since I feel OK when riding, I'd really like to keep going, but I'm afraid I may be causing some damage.
Before anyone answers with the obvious stuff:
1) I have had a professional fit from someone who is a legend in Toronto cycling. He took a lot of time with me, and I think the fit is spot-on.
2) I use speedplay pedals with tons of float
3) I ride in low gears and spin at a fairly high rpm. I am also avoiding hills completely.
Most years I have some knee pain and I always figure it is just over use. Previously it was always my right knee that hurt. This year my right knee is absolutely fine, and the left knee is killing me.
