Acupuncture - Is it Real or A Sham?

They have found that needles are best for back pain. Acupuncture is more effective at treating back pain than conventional therapies. There is a German team that has found that the patients treated with acupuncture felt pain relief. But the Archives of Internal Medicine study also suggests fake acupuncture works nearly as well as the real thing. Isn't that weird? They feel perhaps the body may react positively to anything needle prick or that acupuncture may simply trigger a placebo effect. I think this is very interesting as I have thought about having acupuncture, but now I'm not so sure.
