I'd say having 10,000 posts has something to do with it :P j/k

Might be a long shot, but are you on any prescription drugs? I can't remember what drug I was on, (it was to treat Crohn's), but after taking it for some months my fingers started getting tingly like you said, which they said I should stop taking it if I get that because it can cause some serious nerv issues or something. I would see a doctor about it either way.
