Almost 7 months ago I had a rt cemented total hip replacement by posterior method. Since then it has been slow going and about 5 weeks ago I suddenly had pains near the top of the front of my thigh, at the side, in my butt cheek, all around my hip area and groin and felt like I pulled something in lower abdomen, felt like I had torn something. I have also been suffering with sitzbone pain which has been on and off for a few months, but more on than off lately. Please advise what I can do at least for this sitzbone pain. I have sent for a cushion but I need more advice if possible.
