A: Those little pinpricks can be an effective way to manage pain. Specifically, studies show that acupuncture can alleviate the debilitating symptoms of osteoarthritis and fibromyalgia. There are several theories as to why acupuncture works. One is that it triggers the release of endorphins, part of the body's pain-control system. Another is that it increases blood flow to the areas of needle insertion. Regardless, find a practitioner who is certified by the National Certification Commission for Acupuncture and Oriental Medicine.
