For about a year now I've had a slight pain in that muscle - the tear drop one on the inside of the knee. It has never been enough to keep me from riding or weight-lifting, even when I was doing 100-150 miles a week during the summer. Sometimes the pain shifts more to the side, and it's always very dull, never shooting or very intense. But persistent and chronic - yes. To the point that I'm serious annoyed by it. I checked with a physical therapist and they gave me some "strengthening" exercises but I don't think it's a weak muscle, I work out too much for that to be the case. Another therapist said it might be weak compared to the vastus lateralis (outside thigh muscle).
Has anyone had experience with a long-term, annoying injury like this? What I don't understand is why this has not improved. I have taken a week, a week and a half off from cycling before and the pain returns every time. If it was a serious injury it would prevent me from cycling and doing squats, but it never seems to flare up too bad, just remain in the background, nagging at me. I can't figure out what type of injury would persist for this long without causing serious damage or healing.
Any thoughts? Thank you!
