#1 - You need a full and unbiased work up first.
One not looking for PD or anything specific.

#2 - While searching to find a PD dx only, you could be missing something else.

Very few drs will dx you based on a 1 time appt , and only with sx being told to them, that is not how it works.
They need to see & test & document over time, unless the sx are very clear & apparent during the appt..

Best of luck on your health journey.
