haha. funny coincidence that i asked my doctor the same damn thing a few weeks ago when i went in there to get my neck checked out (some minor strep-throat garbage). its carpel tunnel. not to freak ya out; it doenst mean you just did something irreversable. it just means lay of playing guitar till it doesnt do it anymore. simple as that. its just a thing that anyone can get from over-flexing tendons, or in a pianists or guitarist's case, cramping your carpel muscles and giving it a numb-ish kindof feeling. i had it bad a few times some years ago, i would wake up and my whole left hand would be numb. scared the hell out of me. really, its nothing big, but it CAN become something big if you ignore it and fight through pain.
ps: typing on a keyboard gets your tendons worked up just as much as guitar would, so choose wisely in certain situations :/
