Many people who have chronic low back pain have found acupuncture to be helpful. But the scientific evidence to support these claims has been mixed, partly because it can be difficult to devise a good form of sham acupuncture for comparison.
Acupuncture for back pain involves inserting very thin needles to various depths into strategic points on your body. Scientific studies have indicated that sham acupuncture works just as well as real acupuncture for back pain. A key point, though, is that both sham acupuncture and real acupuncture relieved low back pain better than having no treatment at all.
So if other treatments haven't helped your low back pain, it may be worth trying acupuncture. But if your back pain doesn't begin to improve within a few weeks, acupuncture may not be the right treatment for you.
