Get an ambidextrous mouse, and try left mousing from time to time. Try to left mouse at work, and right mouse at home to give your body more variety. Use page up/page down to scroll instead of the scroll wheel; scroll wheels are super useful, but ergo nightmares.
But, that's not going to help your work that much. Work on effective communication, which is gathering information from others as much as it is providing information to others. Sometimes the other is yourself. When you see some writing or speaking or drawing that communicates well to you, study it, and think about how you would have done it, and what you can do differently to be more effective. Practice this as well. Maybe you see a manual that's terrible. Can you spend 30 minutes redrafting it and another 30 minutes communicating with the owner to get it updated?
