This chart shows how a pinched nerve, or subluxation, in one area can cause symptoms in a different area. Theses nerve areas are known as dermatomes. This can help locate which vertebra is subluxated.
Example:
If you are having shoulder or back pain, this is most often associated with a subluxation in the C6-C7 area. So you think your shoulder hurts, but it may just be a subluxation in your neck!
