Does anyone have any home remedies for back pain?

My back is very bad, and I've run out of ideas. I do the exercises my chiropractor gives me, I sleep on my back, and I don't over-exersice. I've tried ice packs, heating pads, and pills. Pills never work on me, so I gave up those, and the heating pads and ice packs don't seem to work.

The only thing that works okay is taking a good warm bath because it's relaxing - but it doesn't last very long. As soon as I get out, my back muscles get all tense and I start to hurt again!

does anyone have the same problem as me? Does anyone have any good ideas? Opinions?
