This'll prolly get zapped, but oh well.
Best "cure" for lower back pain for a herniated disc (that is, if it's not caused by a trauma) is doing as close as you can to several backbends to "milk" the disc back into where it belongs. Whenever my back aches, a few of those (which hurt good) and the ache goes. If a backbend is too much to hope for, at least put your hands on your hips to support yourself and arch your back as far backawrds as you can; or put your hands on a table, elbows locked and arms straight, your feet a couple of feet behind you, and let your lower back and hips sink into your stomach. That's a little like the cobra position (?) in yoga I think ... and doing that on the floor is great for stretching out stomach muscles and keeping you limber. And it goes without saying it's your stomach muscles that hold up your spine, so keep them strong!
