...the tingling has been in the side of my finger(which I used to lay over my mouth in the "hmmm" hand-to-chin gesture). The tingling has never resulted in a sore, but it is almost random in its severity. It goes from a tiny "zzzt!" feeling once in the course of the day, to that weird throbbing feeling you get with normal coldsores near your mouth. On days when I can get enough lysine or valtrex into me, it is limited or even goes away for a few weeks.

My question pertains to Alzheimer's disease and herpes. WHat exactly is the link, and is this relatively new in life pattern some sign I am doomed to get AD? I had oen cold sore once when I was  ten years old, then I went through a messy breakup and the coldsore tingling shifted from my lip to my hand and has stayed there, though Ihave not had  an actual breakout since I don't know when.
