Dear Agnes: My own inclination would be to trust experience in whether a symptom is a manifestation of PD. Dr. Abe Lieberman of Ask the Doctor qualifies his answers but seems to be amazingly forthcoming. This service is allied with the National Parkinson's Foundation. I believe anyone can join - I did and my father is the PWP. Very good feedback. I think join-up is at https://www.parkinson.org/ under Questions and Answers - click on Ask the Doctor.
