Does anybody know if acupuncture for back pain really work or doesn't work?

Acupuncture Efficacy. Acupuncture is a method that stimulates nerves and muscle tissue to release stress and relieve pain. If the pain is due to structural damage, such as fractures, dislocation, or malformation, acupuncture may, at its best, provide temporary relief. Also, as not all chefs cook the same, not all acupuncture treatment provide the same efficacy, so if it didn't work, it doesn't mean it doesn't work.
