I've noticed lately that my right leg shakes without warning. I have had unexplained and unexpected pain a few times in my right hip and was wondering if this could be the cause of my leg shaking. It only shakes when I am sitting down. My ankle is sore from it moving so much. i don't feel that I'm anxious about anything when it occurs. I can stop when I become aware that it's happening. Is this something I should look into with my doctor?
