Facets function as guides to align the vertebrae of the spine. Facet Syndrome can result from injury or degeneration of the disc(s). The facet joints are where the back of the vertebrae interconnect to limit motion. They are designed to impart strength, flexibility, and maintain spinal integrity, as well as offer a range of defined movement for each vertebral level.
The facet joints are richly innervated, and facet joints which become too tight, inflamed, or otherwise irritated can trigger symptoms of numbness, tingling, burning, and achy soreness along the nerve path.
