Well the Neurologist told me two yrs ago I have PD Well this yr a new NEURologist tells me I dont have PD , I Have Essential Tremor, And if you are young with PD ,and are taking Sinemet cr ask why I was told from two diffrent neurologist that 38 is to young for that med, its for later . If you are not happy with your DR. fined another one if I didnt I would still be on sinemet cr . It doesn't hurt to ask ?? ??. Audrey C From CT :)
