First up, go to a doctor, you may get reffered to a specialist. I went to a physio for treatment for my RSI, my main issue was posture (and of course too much typing/gaming/cubing/playing guitar). I had to cut down a LOT (like I bearly used a pc for a year, and took a 7 year break from cubing). Most important thing is, if it hurts stop immediately, pushing through the pain just does more damange.
When playing online computer games, I personally love using the PC controller so I can play it like a PS3 or Xbox. But some times I use a personalized keyboard that I rearranged the button layouts to make it more comfortable and I use trackball mouses that not only help relax your other hand but frees up more room on your desktop as you don't move the mouse but only the ball on top. Plus you can use it wirelessly on your bed so you can lay back and play on your TV.

1. Correct your ergonomics: raise chair height or lower keyboard so that wrists are below elbows.
2. Use a wrist immobilizer (as used for carpal tunnel) until pain is gone.
3 For pain, occasional NSAID (e.g. motrin).
4. If no improvement in 1-2 weeks, see a doc.
5. If still no improvement, repeat 1-4.
Opinions vary widely about rest vs. working through pain.
From "UpToDate" on "management of overuse (chronic) tendinopathy"
The success of conservative treatment frequently depends upon a coordinated program of relative rest, correction of any underlying biomechanical faults, active rehabilitation, and a gradual return to tendon-loading activities.
Ok, cool, thanks for clearing that up.
