I started showing symptoms of pd from early 2015 and was diagnosed June 2016. My main symptom is little left arm swing and the stiffness that causes it and loss of dexterity in left hand. It has felt uncomfortable this past week - seems worse. I am on light dose of Madopar 50/12.5 x 3 a day for past 2 months. I jog 4 kms 3 or 4 times a week and walk other days. I do stretches regularly. Would increased dose help my left arm and hand, or is it hard to tell? Has anyone any ideas from their experiences?
