I have had cramping pain in my left buttocks, Hip bursitis and muscle cramping right above my left knee. At times my left calf. If it's really bad my left foot will cramp. I have had both knees replaced. Back surgery and then my right foot had a tendon repair because all my weight went on my right leg because of my left leg pain. All this for ten years. None of the above surgeries help the pain problem. My Primary Care Doctor made the call of Fibromyalgia. Now I've got slot of research and learning to do. I'm on a pain killer, muscle relaxer and tequila to help with muscle cramps at night. We were able to to deduce when this happened. December on 2010 I almost died of Hypoxia because my Pain Mgt Clinic user methadone for pain. At the time I had atypical facial neuralgia. A local hospital saved my life. Two months later the symptoms started and have lasted ten years. I've dealt with depression and sleep problems. The VA is going to love me!
