Have you ever tried switching to using your left hand for the mouse. It is generally recommended for ergonomic reasons even if you don't have a keyboard issue. It'll seem weird to your brain at first, but I got used to it pretty quickly, as did everyone I know who has tried.

When I was in grad school (before I had any ergonomic pains), I had my mouse on the left side at work, and the right side at home - so I was using both configurations daily.

I switched to mousing lefty a long time ago. If you want to get up to speed, just play a few games of solitaire or something like that.

Unfortunately, gaming while mousing lefty is often inconvenient. Many games are set up assuming your left hand is on the keyboard. In most cases you can re-bind the keys though.
