I have knock knee's and I'm a 29 year old year old who had ortho. knee surgery on my left leg . I have had nothing but trouble since. My back has gone bad...my other knee is now hurting, and my left leg is now a inch shorter than my right. I have degenaritive disc disease in L4,L5, S1 and osteopinia. The doctors don't know what's wrong with me. I have a three year old daughter and it's hard taking care of her. My doctors have even suggest neropathedic pain...which I am not depression! I wish it was that simple. Anyone have any suggestions?
