I developed RSI, not in my wrists, but in my R hand and fingers. I did not realise this was happening at first so took painkillers. Absolutely the worst thing you can do as you feel less pain so continue to do the very work (in my case mouse clicking) that will cause you even more pain. It got to the point that if the fingers of my R hand touched any surface it was very painful. The company were helpful, but the best change was switching from a mouse to a wacom tablet. Please do not ignore finger/hand pain.
