The spine is divided into 5 main sections that have a major impact on all areas of the body.
Within each spinal section, there are individual vertebrae that align down the backbone.
When these become misaligned, you can experience symptoms in other places of the body. Sometimes these symptoms are intense and immediate, while other times you may not even notice it.
Spinal health is extremely important for the overall health of the body.
