Kathy,
I have a herniated disc in my lower back and suffer, at times, from sciatica.
I find bed rest, lying on my side, knees tucked with a pillow in between my knees helps, as well as taking Advil or Extra Strength Tylenol. I also have a very good shower massage and when my back flares, I stand in the shower and let the massage concentrate on that area. I try to make the water as hot as I can stand it.
I have had two epidural steriods injected into the bulging disc some time ago. This seemed to ease the pain, somewhat, but the problem persists and I just learn to deal with it as best I can.
I hope you're doing better very soon! Please take care and let us know how you're doing.
