guys, I have never had this problem before, but im using an ntour 95 pre-strung which ive had for almost 2 months now and for some reason my hand has just begun hurting right in the middle of my palm and all the way across. im pretty sure its because when i hold the grip in my hand and i swing too hard like on my serve usually and i think it might be that the vibration is going all the way through the racquet and down into my hand. if this keeps up i might have to quit for a while. does anyone have any thoughts on why this is happening? im thinking that it might be these terrible strings i have in my racquet. they are pretty stiff. i appreciate any feedback. thanks.
