There is not much more to say than this. Your nervous system controls EVERYTHING in your body – every cell, tissue and organ. If your nervous system hasn’t been checked then you need to have it checked. The way to do that is to see a chiropractor for a spinal evaluation. At that point you then have the information you need to make well-informed decisions regarding your health. The absence of symptoms does not mean you are healthy. Change the way your thinking, make your health a priority, and go get your spine checked.
