I too had right hip removed because of a staph infection; I've been cleared of staph. I have no spacer in the hip and I am in a lot of pain when physical therapy tries to work with me so I have made very little progress in walking. I also have a deteriorating back which causes a lot of pain along with groin pain which I can't seem to overcome and walk. It has been 5 months now and I still can't walk. I want a hip replacement but the surgeon says I have to be mobile before he can do surgery, it is so frustrating.
