I have been taking amlodipine besylate 10 mg, and simvastatin 20mg for years. In the last year and a half I have noticed shakiness in my hands, which is worse when i am stressed. I also take diovan and sertraline which my doctor wonders about. I really have no other symptoms of parkinsons and was only recently made aware of mixing those first 2 drugs. My doctor is new to me, since mine retired. I can t communicate with her that well. Any insights would be most appreciated.
