I can't spell repetitive

I ruined both wrists in a horse riding incident, both are really weak and get strained easily, I'm a 21 yo with the wrists of an old woman, have to get people to open bottletops and have walked into doors a few times as my wrists just crumpled.
It really is not worth straining them if there is a chance of hurting yourself, because it sucks bigtime.

Someone earlier mentioned making sure your seat posture and height is right, it really really does make a difference though it sounds stupid. That and wrist supports most likely will let you play normally with no problem, unless your playing like 12 hours a day, the movement itself should not be causing the pain unless your wrists are injured already, so if you can work out what is causing it, you may not have to make gaming changes.
