Do you stretch your neck and back muscles before shows/practice? It sounds gay, but if you make sure to stretch before getting nutty, you'll feel way better after shows/practice.
One effective stretch is to basically bring your head down to where your chin is touching your chest (slowly) and then grab the back of your head as you would your girlfriend's when shes going down on you and gently pull. Don't mimic her head bobbing action or you could pull a muscle and your gig will be painful. After a few seconds of this, slowly (Slowly!) turn your head as far as comfortably possible one way (while keeping downward pressure on your head with your hands), and then the other way. Also do the old bend over and touch your toes thing. Don't worry about keeping your legs straight, although it won't hurt to stretch those either. This should stretch your back muscles a bit.
Some times when you're at a show its hard to find time for this, as you should do it as close as possible to your set, but if you have to, do it onstage while theyre soundchecking the drums. It may look funny and un-metal, but if you'll be glad you did it when all your bro's can't lift their heads because they pulled muscles. Also, with you getting nutty at practice, you're building head banging muscles. You'll be doing alot better on the tours than your band mates.
