Chiropractic is a health care and pain relief technique based on proper spinal motion and nervous system function. Through normal wear and tear on the body or because of injury, spinal joints can become restricted and inflamed. This causes interference with and irritation of nerve roots exiting the spine, which causes pain and other health problems. By providing gentle manipulation to these spinal joints, a chiropractor decreases these restrictions and inflammation, restoring nerve function and spinal motion. This decreases pain and restores normal function.
