I am at the end of my rope!!!! My mom injured her knee over a year ago. She has been to doctors, therpists, chriroprators, and even a gym to try to stop the pain. It started with her knee hurting which she thought happened when she was walking down a bank to a lake and twisted her knee. The pain got worse and worse, after about 2 months she went to her general doctor which could find nothing wrong with her leg or knee. She then tried a chriropactor which said that the mucsle was weak, but for over a year nothing they have done has helped. Her leg is swollen most of the time, the knee pops out of joint and is very painful. She has been to at least 10 different doctors or whatever else not one of them has been able to help. She is now unable to lift her leg to climb steps or to get into her vehicle, she hasn't slept more then 2 hours at a time for almost a year, she is depressed and in extreme pain most of the day. I dont know what else I can do for her. Please help!!!!
