Even small chiropractic adjustments can help regulate blood flow to the brain. Decreased blood flow to the brain often results in headaches or even migraines. Simple adjustments can often eliminate this. Research shows that spinal manipulation – the primary form of care provided by doctors of chiropractic – may be an effective treatment option for tension headaches and headaches that originate in the neck.
A report released in 2001 by researchers at the Duke University Evidence-Based Practice Center in Durham, NC, found that spinal manipulation resulted in almost immediate improvement for those headaches that originate in the neck, and had significantly fewer side effects and longer-lasting relief of tension-type headache than a commonly prescribed medication.
