I need answers. I had a total knee replacement on December 4th. I have since developed lymphdema in my left leg. I am going to therapy and it doesn't seem to be working. It is extremely painful and I am having problems doing my therapy for the knee replacement. Is this something I am going to have forever now and what type of exercises are there to do for this? I am at my wits end trying to deal with this. Any help would be greatly appreciated.
