I had shingles about a year or so before I was diagnosed with PD. It was on the left side of my chest, the same side on which I had the only real tremor I've had. I'm left handed. It was a strange rash. It stopped as if a fence had been built right down the exact center of my chest. i also had that shoulder pain that was discussed awhile back, mostly on my left side. I was somewhat careless with garden poisons, and I've drunk well water most of my life. I think i've done just about everything that's been discussed hereas being a cause, or so it seems. (I never played with Mercury, though, rolling it around like play dough like one of our felllow list members once reported.) Did I stack the deck or what?
