Yup.. me too.. and though I can last more than one song these days, once it starts to hurt you're pretty much dead in the next 10 to 15mins of constant playing in the same way..

It's really the tightness of your muscles, so if you are gripping the neck too hard, your muscles are very tight.. so even if you just held your hand muscles tight for the same period you would have the same problem..
