I can certainly sympathize with your position and Sue's answer is right on target. I had my TLHR in Feb. and also had no PT or exercises until I insisted long enough and my surgeon referred me --after 20 wks!. SInce then the hip itself has healed fine (not considering a small bone-piece displacement which is not causing trouble) but I still cannot bear my weight on that leg, just as you say. However, all the pain is gone; the muscles are just too weak to support my weight. I've been having weekly video visits with my PT for just over a month now. Flexibility and stamina have improved immensely but the weight-bearing is going extremely slowly. However, I had been using a cane for nearly a year prior to surgery so there was a lot of muscle-strength lost.
Be sure to get going with physical therapy. I think the pain should start improving very soon but I think you will just have to be patient until the muscles heal and regain their strength for full weight-bearing again. Hang in there and stay positive!
