Especially if you have right arm and/or neck pain and stress, consider changing your mouse hand to your non-usual/non-dominant side. It will give your dominant/usual side a much needed rest and often leads to recovery from the pain experienced. Also, it’s good to learn new things (it is said that people over the age of 40 rarely think or do anything new out of what is habitual…something worth thinking about)! Admittedly, you won’t hit anything with that little cursor arrow for about 2 hours after switching, but eventually you will get the hang of it and create new neural pathways in your brain (which is a good thing). Then you can alternate hands by the month and keep both sides stress free!
