FK – I started having lower back problems when I started using computers. Sat in a folding metal chair for hours a day with bad posture. The chiros have been a help but look for the ones who actually fix you and don’t expect you to come back all the time. I have to go 3 – 4 times a year on average. Go when you start noticing a problem, don’t do what I do sometimes and wait until serious pain begins then you can be locked up for days. And get a real office chair and get up and stretch or walk around and do something different from time to time.
