My hands have been steadily developing a painful symptom when playing. So far this has only happened with StarCraft and games similar to it (such as DotA). What happens is that after playing about 3 or 4 games my hands start to feel extremely stiff and painful to move (almost like cemented in the home row position for touch typing). My fingers look and feel bent in a very unnatural position and just refuse to move. There's also a faint pins and needles feeling in them (though not as prominent as say a leg falling asleep). I usually finish the match I'm in and quit after that. It's really bothersome when I want to keep playing but it greatly reduced my ability to play matches.
Really hope it isn't anything too serious.
The same thing has been happening to my right elbow. I think that I may be getting arthritis in my elbow though.
It sounds like RSI (repetitive strain injury), its pretty common for gamers who play games that require a lot of continuous rapid clicking, or keyboard action. Go see a doctor about it, depending on how serious it is, it can be managed or healed.
Yeah, it sounds a lot like the kind of stuff that RSI blankets. Definitely see a doctor. Probably just wind up with a referral to an orthopedic surgeon to actually get anything done, but hey.
