At night when I go to bed parts of my body jerks. Sometimes both shoulders, sometimes a foot or a muscle and other parts of the body. Also, my fingers lock. Plus, my hands aren't steady and my legs feel weak. I'm 72 and have been on Lipitor for about five years. I don;t if I should stop taking it and what I should try. I take 500 mg of Vit. C and omega 3.
