Spinal dysfunction (often referred to as subluxation) will present itself in a variety symptoms. Everything from back pain and headache to constipation, anxiety, PMS, heartburn, leg/knee pain, and shoulder and arm/hand pain. In children it presents as colic, ear infections, constipation, reflux, and sleeping disorders. Until this dysfunction is detected and then corrected via chiropractic adjustments, those symptoms will continue to present.
