We've all had it during long gaming stretches. Your arse starts to get sore, it itches, it becomes very uncomfortable to sit.. how do YOU deal with it?
If you get a sore butt from gaming too long you are obviously a light weight.
I've had a lot of times where I had serious pains in my arm and fingers from frantic MMO/MOBA/FPS playing however, but I kind of have a medical condition that causes those so I'm not 100% sure its solely to blame on the gaming.
I play games in like 6 hour chunks at a time so this has been a problem for me in the past but I got in the habit of standing up every 30 minutes to an hour in order to pet my dog (not a euphemism). That way my ass and eyes get a couple minute break every once in a while.
Yeah I fucking hate my office chair. It's cheap but it's the worst. Never skimp on those, that's my new policy for life.
But whatever I ultimately just stand up and walk around a bit, head to the basement and grab a water bottle or something.
Although now I find myself considering getting a standing desk. It seems like it'd be great for work but terrible for PC games.
