Years ago I started to suffer from carpal tunnel pain. It was painful to maintain fine mouse movements and click the buttons. Typically the finger movement to click a button would make the mouse move away from where I wanted to click. And the pain in the wrist. Solved it by placing the mouse on the left with the tracking window covered. I have a trackball for the right hand. So I position the cursor my moving the trackball, lift my finger and then click or wheel with the left hand. Can still click with the trackball if my hand is over the keyboard for infrequent operations. Don't have to think about it and no more wrist pain.
