Was skeptical, but back was in such pain that in '04 I tried it. Took a few treatments before responding, and almost gave up, but had a "cupping" treatment, and the next day I was instantly better. It is now 8 years later and for the past four year I go just quarterly for a "tuneup". Had one other cupping session about 5 years ago, and all is well.
Try it, but give it a chance to work (maybe 5-6 sessions the first 3 months).
