Chiropractic works because you are a self-healing, self-regulating organism controlled by your nervous system. Millions of instructions flow from your brain, down the spinal cord, and out to every organ and tissue. Signals sent back to the brain confirm if your body is working right. Improper motion or position of the moving bones of the spine called subluxations can interfere with this vital exchange by irritating nerves and compromising the function of affected organs and tissues. Simply put, whatever your state or level of health is, you are better off with a healthy nerve supply.
