hand and wrist pains?
I have bad posture due to scarring on my chest and when my posture is poor for too long, my thumb, index and middle finger go numb. recently, however, i have had a problem with my grip (which has always been strong). if i make a fist or hold something and bend my wrist like im revving a motorcycle, i have shooting nerve pains in my palm and forearm. is this carpal tunnel? if not, how do i fix it? is it a pinched nerve? if i keep my back straight, i dont get numb fingers but i still have the shooting pains problem...
