Has anyone had acupuncture for lower spinal pain with good results?

Yes I do that: I have been using system called p stem, which a continuous , computerized acupuncture implanted in the ear loop for 3-4 days to treat back pain, so far I have 60 to 70% good result from it. Check that web site.

Acupuncture: Yes. I have treated this a number of times with auricular acupuncture with good results. The World Health Organization has categorized acupuncture for back pain as "Diseases, symptoms or conditions for which acupuncture has been proved – through controlled trials—to be an effective treatment."
