I was diagnosed with MSA three weeks ago. I was prescribed 2 Sinemet tablets a day. Since then, my symptoms have gotten worse. I went from crutches to a walker and now have difficulty getting out of a chair. I have pain in both arms near my shoulders. Could the Sinemet be making my symptoms worse? How long does it take before you know if the drug is working or not. I do not return to the doctor until February.
