Arm/shoulder pain with mouse usage
For about 6-8 weeks now, I have been having some increasing discomfort in my upper arm/side of shoulder when using my computer mouse.
My arms are resting either on my armrests or on the desk. My mouse is next to my keyboard.
However, when I reach for the mouse and outstretch the arm, it aches?
My wrists are fine and typing is fine (although I do feel it slightly when I type).
Any ideas what this is? Any types of therapy I can do myself to strengthen or help reduce the discomfort?
A friend suggested a nice trackball so that my arm doesn't have to move.
