If your injuring yourself by using the computer where others aren't there's something about you, or the way you're using the computer that's causing you injury.

If your injuring yourself by using the computer where others aren't there's something about you, or the way you're using the computer that's causing you injury. The best advice I've found is to just check, every 10 minutes or so, am I comfortable? How could I relax? Ask these questions of your fingers, wrists, arms, elbows, back, neck etc. Sit correctly (google for advice on that) but don't be tense. I also found the Alexander Technique quite useful <http://en.wikipedia.org/wiki/Alexander_technique> http://en.wikipedia.org/wiki/Alexander_technique>.
