These are 4 sessions that focus on the neck, upper chest, thoracic outlet area, face, jaw, eyes, to support the neck and head in particular, along with the shoulder girdle area.  If you have issues with holding tension in these areas, and need support for head / neck / upper trunk symptoms, this would be a great combo pack.  4 for the price of 3.  With faith means there is scripture read at the beginning and end of session and breath prayer related to it.
