oh wow, i hope you guys are right... i'll avoid that maneuver for a few days and hope it goes away. very frustrating cause it is not pain just oddly sensitive, similar to that of getting hit in the funny bone only its pin pointed on the tip of my thumb. very strange. but thank you for the advice.
mine was through carring my new born baby any extra weight can cause these feelings
It's probably a pinched nerve in your thumb, should go away on its own, I am guessing a week or so if you don't use it again. If it does return you could have a sensitive nerve there (I've gotten them on the side of my thumb from barely hitting something).
Were you my brother I'd recommend you not stop playing, but stop that maneuver that puts pressure on the thumb until you can do it pain free.

but it is pressure i'm putting into the neck of my guitar, not my actual bodily neck. but thank you i will ask my doctor about that possibility.
it sounds like the pressure you are putting on your neck is causing these feelings,i always gets pins and needles followed by numbness in my hands and fingers and my doctor examined me and told me i have damaged the nerves in my neck
