Super Sensitivity in thumb pad...

[m23dj14]

About a month ago I was using a spray can to put a coat of clear gloss on a wooden table... After holding down the spray can for some time with my left thumb, i noticed that when i stopped, there was a very severe case of what one may call numbness, others may call super sensitivity from the pad to the tip of my left thumb.  I expected it to go away after a few minutes, but lingered for almost a day.  I did not think much of it, but I have began to pick up the guitar this summer, and a certain chord calls for me to put a little more pressure into the back of the neck of the guitar with this same thumb.  I noticed maybe a half an hour of practice that this same super sensitivity returned and again has continued to linger.  I obviously do not intend on stopping my practice of the guitar, but I wanted to make sure that I was not dealing with anything serious before i threw caution to the wind and just kept playing.  Any ideas? Thanks

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

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'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.

mine was through carring my new born baby any extra weight can cause these feelings

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.
