Acupuncture for headaches and migraines works better than pills, but not much better than placebo

Reuters - Needles, not technique, may be acupuncture key

Acupuncture works better than painkillers at treating headaches and migraines (and possibly preventing their onset) over an 8-week period. However, untrained or random placement of needles worked almost as well for headaches and just about as well for migraines. The theory is that endorphins (that relive stress and pain released by any needle or acupressure treatment) added to a placebo effect explains acupuncture's efficacy.
