I have had similar issues in the past. The primary solution was to invest in an ergonomic work desk setup. The following elements are all important: - height-adjustable desk - monitor floating on an arm - keyboard tray with adjustable tilt - high-end office chair with many useful adjustments - ergonomic input devices With everything adjusted appropriately, I work in a perfect posture all of the time, without any strain, whether sitting or standing. I used to have pain and headaches all of the time, but now I only have them when I have tried to work away from my home setup. (I've since developed a good setup for working away from home, if anyone is interested.) Other things I think are very important: - Take breaks away from your desk as much as possible, for as long as possible. I like to go for a walk to think, and then come back to the desk with a plan of action. Remember that (if you're a typical HN software engineer) you are paid for what you accomplish, not for your chair time, so thinking time away from your desk is still working. - Be physically active, including things that promote mobility. I find that the best approach is to make exercise something you do as part of life, not as a distinct activity.
