I did this when I was using Photoshop in college and started destroying my right shoulder. Now I have a wireless mouse I switch from hand-to-hand every so often to ensure I'm ruining both of my shoulders instead. Using a mouse on the left side as a right handed person is amazingly fast to pick up. It's also really useful when showing people how to do things on a computer as you train yourself on the mouse, rather than just the muscle memory.
