please forgive me for giving advice.
Thanks Peter... I do know most of these things... over the years I
found that holding devices in a static, cramped position (not to many
options with a mouse) aggravated the problem. With a big trackball I
could actually exercise my hand while working and the arm movements
were in a smaller circle.

Keyboarding certain types of input is definitely faster than a mouse,
but far more hazardous to the health of human wrists and arms.
If this information does not apply to you, please forgive me for
giving advice.
Most of the people I have run across who have wrist and arm problems
from keyboard or mouse use found relief by lowering the surface the
keyboard and mouse sit on. That surface should be lower than your
elbows when sitting comfortably. You should have to reach down to the
keyboard and mouse.
The reason for this is that when reaching up, the nerves and muscles
in your arms and wrists do a z-bend, which they don't like.
Straightening that bend a bit does wonders.
