What the evidence actually shows.

A 2017 clinical practice guideline from the American College of Physicians named acupuncture among the recommended first-line, non-drug options for chronic low back pain. The National Center for Complementary and Integrative Health rates the supporting evidence as moderate quality, and an NIH-funded study found acupuncture eased the disabling effects of chronic low back pain in older adults.

A major review pooling data from 10 studies and 2,413 participants found acupuncture more effective than no treatment for osteoarthritis pain. A companion analysis of 9 studies and 2,376 participants found it more effective than sham acupuncture. Follow-up research on durability found the pain relief and functional improvement can last up to several months after treatment ends.

A systematic review covering 22 clinical trials and 4,985 people found acupuncture reduced migraine frequency, with effects comparable to preventive medication. The American Migraine Foundation considers a course of at least six sessions a valuable option for patients willing to try it, though long-term effects beyond a year need more study.

Meta-analyses of randomized trials show acupuncture outperforming standard medication for abdominal pain in irritable bowel syndrome, with more consistent quality-of-life improvements. Evidence specifically for IBS with co-occurring anxiety or depression is still developing, though early results are encouraging.

Here the research is genuinely mixed, and it's worth saying plainly. A 2013 Cochrane review of 9 studies and 395 participants found low-to-moderate evidence that acupuncture improves pain and stiffness compared with no treatment. But the same review found moderate-level evidence that acupuncture's effect doesn't outperform sham treatment for reducing pain or fatigue, or improving sleep. It may still help as part of a broader plan, but it isn't a proven standalone fix for fibromyalgia.
