Mark, I am also newly diagnosed with pd, about 5 or 6 months, and know there are lots of folks on this list who are more knowledgeable than me; but when I have severe shaking spells (dyskinesias?) I hurt badly all over. From what I understood from my dr, the shaking is sorta like souped up muscle cramps, and when it's over, you have all those toxins in the muscles the same way a cramp or strain will leave them. I alternate heat and ice (doing so tonight as a matter of fact) and it seems to "heal" faster. bob
