Seeing a chiropractor or engaging in light exercise relieves neck pain more effectively than relying on pain medication, new research shows.

The new study is one of the few head-to-head comparisons of various treatments for neck pain, a problem that affects three quarters of Americans at some point in their lives but has no proven, first-line treatment. While many people seek out spinal manipulation by chiropractors, the evidence supporting its usefulness has been limited at best.

But the new research, published in The Annals of Internal Medicine, found that chiropractic care or simple exercises done at home were better at reducing pain than taking medications like aspirin, ibuprofen or narcotics.
