Sept. 04 my left knee was replaced. Nov. 04 my right knee was replaced. I have continued to suffer with extreme soreness in the calf muscle of my right leg. I have soreness, heat, and pain in both knees. Both my knees crack and pop whenever I stand from a seated position. My dr continues to persist that they are FINE, and I only need to walk, walk, walk. I feel unsteady on my feet when I walk. I cannot go up or down steps without pulling myself up and holding onto railings to go down. I am concerned that I have suffered this tremendous pain and suffering without improving my mobility. My dr is very discouraging.
