Basically, if you play with it regulated, like they said, it shouldn\'t hurt. I however have played about 70% of my paintball unregulated, and as long as the people there aren\'t assholes, they shouldn\'t be playing at that high a speed anyway. I have played upwards of 20 times, and only once have I been hit and had it really hurt, and that was from close up in the neck.
I once saw someone have tears brought to their eyes by a hit, but that was an accident. Some jackass was fooling around with a gun he thought was empty, had the barrel against the other guys skin, and shot, not realizing there was still a paint ball in the chamber. The thing looked like a real gunshot wound, I swear.
Honestly though, if you are afraid of the pain, my advice is to just wear loose fitting clothing. It slows the pain enough before it hits you that it doesn\'t really hurt. I really wouldn\'t worry about the pain. In my experience, it\'s nothing too bad.
