I have had alot of back pain, w/ or w/o pregnancys. I have deg. disk disease. What works best for me, may not work for you.... for me, I try to stretch my back as much as possible. by laying on the floor and crossing my legs over my body...left and right. Pulling my knees up as far as I can, doing a "cat stretch"... Anyways, stretching works best for me. Also when my back is at its worst, I do not sit still, I try to keep moving to keep my muscles from tightening even more. Hope some of this info helps you a bit!
Take care, and Blessings~ JUlie
