ei555 I have short of the same thing you do... except they don't feel cold, and it's on my the back of my right hand, on the right side, about the size of half a credit card, but roundish. It turns red when I'm hot, and purplish when I'm cold. I've had this problem since I was in Elementry, and I still have it today (13th grade).
Anyone know about this thing? I would sure like to get rid of it, I'm embarrased about people asking me about it.
