My job is a lot of quick computer work (if only my in game APM could be like my work APM) so my wrist doesn't really get a break.
Would spending some time at the gym specifically devoted to wrist strength training work? I already do stretches for my wrist/forearm.
Not only do I play Starcraft 2 and make similar movements at work, but I also play counter-strike competitively, which involved a lot of twitch mouse movements and fine aiming.
TL;DR - HOW DO I PREVENT CARPAL TUNNEL THIS TIME AROUND?
in before get your arm rebuilt a la Flash
