For any headache sufferers out there – Did you know that a large study performed at Duke University in 2001 found that patients treated with chiropractic adjustments fared better than those treated with a commonly prescribed drug to treat headache? During the four weeks after the treatments were discontinued, patients who were adjusted felt “sustained reduction in headache frequency and severity,” while headaches returned to those who took the drug. Not surprising – the drug masks the symptom, chiropractic treats the cause.
