Another back pain sufferer here but the pain/discomfort is mostly under control due to exercises to strengthen core muscles. Get a book or scour the web for exercises for such strength work. I begin my day with such exercises even before getting out of bed. It's part of my startup morning routine like brushing teeth. Also, when back twinges begin to encroach on your day, laying flat on the floor, as suggested above, or any exercise that puts your back in mild traction, will help realign things. The principal thing that keeps the various joints aligned is muscle keep 'em strong.
