I have a job that requires 8 plus hours of computer use a day.  Recently, I was diagnosed with Carpal Tunnel, Radial Tunnel, and Ulnar Nerve (I think the term was ulcerations) in both arms.

When I rested my wrist on the pad it made the pain worse because it pushed directly on some of the problem spots.  If you are dealing with similar medical issues, I strongly recommend purchasing a wrist brace like the one linked here:
