I can sooo relate to this. If I could give up work entirely and live a life of leisure I'd be so much better. I also sit at a computer all day. I think posture is a big culprit. Do not sit with your head pulled forward away from your body, if you lean in to your desk to type, or write, move your back in line with your head, if you see what I mean. Head pulled forward is bad. See if you catch yourself clenching whilst you work. Could be another factor. Otherwise it's just stress - work stress makes my symptoms worse, no question - then again, having no money and not being able to pay my mortgage would be even more stress. It's a big problem, I share your frustration, been pondering this dilemma myself. Lottery win?
