If the surgeon was able to pinpoint the muscle location of the pain, I suggest you ask the therapist to try pressure point massage therapy (also can be called trigger point massage therapy). It can take a while, but this treatment uses finger pressure on the point of pain to release and relax the muscle fibers. I've been having this type of therapy for about a month to help with muscle issues after my THR (August 23) and the result has been amazing. I hope you can find a therapist that knows this technique.
