I have noticed lately that my right hand has been hurting while using the mouse...more specifically, the knuckle/joint in my pinky that grips the side of the mouse.
I have been playing FPS games most my life, but more intensely since I began college in 2004. Since then I have got a new mouse every few years...first it was a G5, then a Razer Copperhead, and now for the past year or so has been a G9x. The first two are a bit more natural to palm grip, while the G9x is more natural to finger grip. Could this be to blame for my pain?
