I had leukemia and I had a bone marrow transplant. I got graft vs host decease. I was put on steroids straight away which I go avacular necrosis (servere arthritis) in my hips and knee; I am in a wheel chair. My doctor thinks I have to get my hips replaced. I am in a lot of pain and need strong pain killers. If I have this procedure what will I be able to do for work, what happens when they wear out. Im dreading what will happen in the future.
