You may be suffering from a condition which involves more than just muscles. The health of the spine is dependent upon the individual movement of each of its 24 vertebrae. When one of these joints becomes injured and doesn't move the way it is supposed to, it can cause irritation of the nerve that exits between the vertebrae. These nerves control every function of the body including the voluntary muscles of the spine. When these nerves are irritated, they cause muscles to spasm.
Spasms cause pain.
The condition where abnormal function of a joint interferes with a nerve is called a subluxation. Dr. Williamson founded the West Coast Heelers Running Club in Santa Cruz, California. The club sponsors Special Olympics while raising awareness of the benefits of regular exercise in the community.
