I am starting to think I am not supposed to be cycling. it started bcd in november with what i thought was a stress fracture. turned out to be tendonitis in my left leg (near the knee). After that, I was just cleared by a doc to cycle after undergoing a barrage of testing for chest pain. So, excited, I left work early today to go cycling, and my knee begins to hurt a few miles in. I tried to adjust my cleats a bit, and that seemed to prolong the onset of the pain again, but it came primarily during climbing in the saddle. Here is my a description of my pain: left knee only, directly under the center of my knee, in the front, and goes away if I stop. I adjusted my cleat to make sure it was right behind the ball of my foot, but what other remedies can I try? Should I raise my seat a bit if it is only one knee? Any help is appreciated, as I am tired of being off of my bike.
