My wrists and forearms are starting to go bad and it's definitely from drumming. I know for sure. I'll have to change things up a bit, get more technical, and learn a few more things but I promise that I'll still be really good, because I don't quit.
For some reason, after the last few gigs, my wrists are screwed to the point that I can't do a massage without pain. It is with much regret that I have resigned to be a softer hitter. It's just part of becoming a geezer. I'll still smash like a maniac on select songs.
