Man, I feel my heartbeat too, always, every single one, thats crazy... I remember just the day it started, about when I was 15 or so (8 years ago). I also have cold-pinkish face and feet. And I discovered that "raynauds" is just another name for acrodynia, a disease caused by mercury: acrodynia

its ridiculous how they change names to diseases in order to confuse people... heh, raynauds is a mysterious syndrome, the causes are unknown... right...
