Pushing yourself too hard on the exercises or riding?
Your body will tell you if you are pushing too hard on the bike.
What I found frustrating in my PT experience was that my problems got worse before they got better. My first go-around started in earl April 2010 and I wasn't really "better" until after July. Showed up in my IT band originally but was diagnosed as being caused by my hip being out of alignment. But then I had things hurting in muscles attaching to the hip. The PT included stretching and strengthening. I did short easy flat rides after a while. By July I was back to riding pretty normally- rode Mt. St. Helens on a trip to the northwest.
