I think maybe I should have just focused on the chair advice. I understand the whole "go to a doctor" thing makes sense but I don't have much money to do so right now. My parents have spent over $15,000 out of pocket on doctors for me from traditional to alternative and whatnot over the years and I never really got anywhere with it. I have little money and no health insurance.
What it comes down to is, I KNOW sitting in front of a computer is a major cause of my pain. There might be some other damage I don't know about (though I have had x-rays and a spinal evaluation which both came up "ok") but it's a very noticeable thing when sitting in front of a computer. Before this job I was teaching PE and my back and neck were the best they had been in years. But that was a job I sort of fell into, I don't have a teaching degree or anything so I can't really just decide to go do it again. Before that was more computers, and yes, more back and neck pain.
Maybe longterm I need to get out of computers. I dunno. But if so I'd probably need more schooling in some other field or something, so that's not really going to help me in the shortterm.
ANYWAY... as for the ergonomic chairs, anyone have any real experience with them? Everything I read is glowing and there seems to be real science behind them, but it's also tough to trust online reviews.
(Oh and I'm not overweight. About 170, which is probably underweight if anything.)
