I would like somebody who's had some experience, preferably a doctor or physician or something. I've been having headaches and not feeling so good usually after headbanging. Sometimes I have whiplash too and nausea. Although this could be resulting from a bunch of other things, like stress or some bug thats going around...I just want to know if headbanging has any potential for serious brain damage. I know the evanescence dude got a stroke from it...
