I don't want you to think I am saying that you don't have the problems mentioned but you sound a bit frantic. If you don't think the neurologist is helpful try to find a "movement Disorder" specialist. These specialist are more experienced with PD than most general neurologists Most neurologist cannot say exactly what is PD related and what is not. PD symptoms are vary between individuals. In my case I had PD after a rear end accident and 2 strokes from the brain hematoma. Whenever a new symptoms appears we do an educated guessing game on what caused the new symptom.
Good luck
