I’ve been going the nutrition route and changing my ways. I use to be a hostess ding dong aholic. Have you looked into answers for sciatica through nutrition and seeing a homeopathic dr.?. . .I just gave the above link because I know “Joel Wallach” is about nutrition and minerals. . .I’m not advocating anything. . . but you might check out Dr. Mercola www.mercola.com and Dr. Axe www.draxe.com They are into the nutrition as well. May beat downing the tylenol, motrin, etc.
Sciatica is basically nerve-pinching, and has more to do with discs not quite being lined up or along those lines. It is a literally mechanical problem.
