A friend recently told us that someone he knew was diagnosed with a significant heart problem...he wisely went to get a second opinion and the savvy doctor ran some tests and discovered the guy actually had a virus that was making it look like his heart had a problem. Took care of the virus and end of problem.

We can't help but wonder if a virus might be at play in the whole PD scenario, and so...

If someone wanted to get tested to be sure they didn't have any virus lurking around in their body, what tests do they get? Who do they go to-a virologist or an immunologist? Maybe a lurking virus causes PD outright or sets the wheels in motion, or maybe it only makes symptoms worse, meds not work as well, etc. But we are thinking of going to someone to be sure a virus is not at play anywhere.

Any experience or advice on this anyone may have would be very much appreciated, thanks.
