Neck Pain Relief.

Three groups received either spinal manipulative therapy from a chiropractor, pain medication (over-the-counter pain relievers, narcotics and muscle relaxants), or exercise recommendations. After 12 weeks, 57% of those who met with a chiropractor and 48% who exercised reported at least a 75% reduction in pain, compared to 33% of the people in the medication group.
