I twisted my right ankle several weeks ago . Dr. took x-rays, MRI, no break or ligament/tendon tears . I still have a lot of pain in my right ankle & outer edge of my right foot. I have a burning stinging sensation along right side & outer edge of foot & ankle also very sore & tender. A side bar I do have early onset Parkinson disease which affects my right side only . Don't know what else to do. Any suggestions, comments or similar problem PLEASE HELP THANKS
