70% of all headaches are musculoskeletal. It is estimated that nearly every American will experience head and/or neck pain in his or her lifetime. 157 million workdays are lost each year due to head and neck pain costing some 55 billion dollars in lost productivity. 1.3 million school days are lost annually due to head and neck pain in children. Ironically, unlike lower back pain, most people do not actively seek treatment. Instead, they self-medicate or depend on prescription drugs for what is at best only temporary relief and, at worst, a form of substance abuse with its own medical consequences.
