My personal opinion, can neurologist #2. 1. He knows nothing about Parkinson's and the medications used to treat it. 2. He is just an idiot. You decide.

I hope I didn't get too technical for you.

It has been my experience over the past 10 years, doctors will differ in thier diagnosis somewhat. That being said, a pig is still a pig no matter what type of mud it rolls in. If you are responding to dopamine then it is a pretty good bet you have Parkinson's or Parkinsonism. In some people protein does block the action of dopamine completely. Others can eat protein whenever they like and not have this affect. Pain is a real symptom of Parkinson's disease. Yes I agree that daily stretching exercises can help relieve the pain. Key words here, CAN HELP.
Vision problems are well documented in regards to Parkinson's disease

As I stated in the begining, cross doctor #2 off your list and be sure to inform all you come in contact with about him.
