Since this spring, I started to feel minor pain in my right hand wrist and shoulder. It may be a beginning stage symtoms of Capal Tunnel Syndrom. (http://arthritis.about.com/od/carpal/ss/carpalstepby.htm)
I know that I use too many softwares at work so I have to move the mouse a lot. To prevent the worse development of the pain, I decided to use Trackball mouse.
In fact there are lots of orgonomic mouse , but they are much expensive than regular mouse! But, Logitech’s Trackball is reasonable $30 (including shipping from online store)
This is the first time that I am using Trackball. So it feels kinda awkward yet.
But I really hope that this one helps me to relieve the pain.
I still somehow look for a better alternative since it feels strange for now.
