I agree with Tom’s recommendation to get a second opinion. You might also want to consult with a different physical therapist. I know from my own experience with my hip that not all PT’s are equally skilled in all injuries, and a different PT may see something that your current PT does not.
My own story is that it took me a year after surgery to be able to run. In order to do that, I had to go back for an additional 3 months of PT 7 months after surgery.
Good luck, and keep us posted.
