sounds like your answer is tied to your surgery. I too would be worried about drug interactions.

I would suggest you see an endocrinologist to eliminate something glandular as a possibility. Anesthesia is hard on your endocrine system.

It's senseless to try and diagnose PD by yourself. There are so many symptom permutations, it would only confuse you. Go to "Find a Doctor" at www.parkinson.org and find a MDS, (Movement Disorder Specialist) near you, and get a consult. IF it were me I'd see the endocrinologist first though.
