In brief: Neck nerve roots

Commonly, the most pain is coming from the largest muscles which is usually the the lattisimus dorsi muscle and other muscles supplied by the c6 and c7 nerve roots in that region.
You can identify these muscles and the surface anatomy section of my classic book and the photographs are available at : http://www.Etoims.Com/content/education.
