Apart from stretching, resting, and arranging an ergonomic setup (e.g. arms at 90 degrees, etc.), are you employing any coping strategies for computer elbow, or that dull ache in an elbow's tendons from computer overuse? If the pain I've been experiencing over the past year or so gets any worse, which it plausibly will without intervention, I can't imagine spending the rest of my life in any industry that requires sitting in front of a computer for a large chunk of the day.
Any tips?
