How does Chiropractic work?

Your spine is made up of 24 individual vertebrae. These bones should all move relative to each other.
Altered function of your spine can cause pain in both the joints, and their associated muscles. It can also effect the underlying nervous system, interfering with the flow of information along your nerves, or causing pain in other areas of your body.
Chiropractic restores function to your spine, decreasing pain and improving general health.
