@Denpucc1 so sorry you're still not getting the answers you want. At least the sports medicine doc sounded like he was being honest with you. Thinking you were sent to him as he probably sees this or very similar issues in his practice.
I would like to suggest that you actively ice every chance you get, wherever you're feeling pain. It really does help, I still do it once in a while and I'm closing in on 3 years post THR.
Also if you're going to exercise, I would suggest that you start very slowly, low repetitions and ease into it. Maybe some nice gentle stretches will help. And, if it hurts, stop. Ice after exercising as a precaution. Maybe see if the doc will send you for some specialized physical therapy.
I know you just want it fixed and over with now but unfortunately the medical system and insurance don't work that way. Would make way too much sense and be too efficient!

. Wishing you the best, just trying to think of things that might help.
