My husband has kidney cancer that has spread to the femur bone. He had the kidney removed and a cadaver put in place of the right femur. This was in the last six months in 2000. Now he has unbelievable pain back in his right leg. He says the pain sometime goes to his other leg, groin area and buttocks. I am told bone scans don't always pick up the cancer, so they are saying it is most likely in the bones. He is on 800mg of oxycotin daily with minimal relief. What else is out there? I hear there is a patch. But what is the cost and how effective is it? Any info is welcomed. Thanks
