Try lying on your tummy propped up on your elbows. (like a kid watching television on their stomach) Lying that way for a few minutes might be helpful. If it helps, do it several times a day. (sometimes it will push the disc or whatever you wolloped out of place moving furniture back into place, then you just keep doing it until it heals back into place after a couple weeks or so)
If your back doesn't behave, head on out to the doc and get it taken care of.
