I used to have serious CTS issues from using a mouse.  Clenching a mouse
and fine motor movement became physiologically incompatible actions for me.

My simple low cost solution is to have a USB connected Logitech trackball
under my right hand (I'm right handed) and a common wheel USB mouse with
the optical window taped over under the left hand. Moving the mouse has no
effect on the cursor/pointer.

So I position the cursor/pointer with my right hand, rolling the trackball,
sometimes gingerly. When I have the spot right, I raise my right hand so
that the pointer stays put and then click or scroll as required with the
left hand.
