i reached for a 22nd fret bend and all of a sudden this tingling sensation shot down my wrist and scared the crap out of me. it wasn't painful or anything, kinda like when you hit your funny bone, it was just startling and felt REALLY weird. so if there are any physiologists out there, maybe you have some knowledge as to what it was (its happened a few times before as well), cuz it's got me a little worried
thanx guys
