I thought I'd made an expensive mistake at first and had the same finger cramps, but a few months and I'd forgotten the problem ever existed - until you posted this!!
I think the main thing I did was to disable the side buttons. I was always triggering something with them by mistake. Now I hold the mouse straighter with my fourth finger alongside and ahead of the side button and my thumb a bit behind the other side button, and it's fine.
I also had a problem with the cursor jumping to the corners. A change of mousemat (or no mat at all) sorted it out. I think it has problems working on screen printed (lots of dots) surfaces.
