Barbara, 7 year to diagnose PD. I went to my GP he took one look at my left arm felt the stiffness and said I have PD. Then he said he was not qualified to make such a call and set up a referral for me with my Nero. He then ran blood test to rule out certain things then he gave me a MRI then he gave me another physical you know like touch your nose, follow the finger with your eyes, walk a strait line. Then he wanted to check all the test results gave me 2 prescriptions said if they helped I had PD. This was my first introduction to Sinemet and Eldepryl and the unforgiving monster called Parkinsons DISEASE.
