My mum suffers from RSI because of a weird mouse she used to use at her workplace. If it's suspected RSI, i have to insist that you rest it liberally, otherwise, as my mum has found out, it can cause alot of long-term damage that could further damage your chances at work, or whatever you may need to use your wrist for (Y)" Seb's explanation sounds pretty informative as well, so it could just be that, so take his advice aswell :)
