I have a chair that I can adjust the heighth on, so I moved it up. That puts my forearm at a higher level than the desktop. Now I'll go get one of those gel support-things....
With all the injuries: broken bones, dislocated joints, torn muscles and ligiments I've had over the years, this is not an injury I would care to get.....
Tiger balm, ace bandages, and a good ice pack are my friends...
