It was about 10 years ago when carpal-tunnel first hit me. Every time I put my hand on my mouse, I'd get spasms of pain in my various parts of my arm. I tried special ergonomic mice and trackballs, but they didn't help. I tried speech recognition software, but it was a joke. Whether I could continue with my profession was becoming an issue. I even tried moving the mouse with my feet. Nose mousing was next.
