Stiff neck is most often caused by the Upper Trapezius, Levator Scapulae and Sternocleidomastoid (SCM) muscles – one or all. U.T massage point is that part of the shoulder you grab between your neck & arm. L.S. is the back of the neck between the skull & top of your shoulder blade. SCM is that diagonal muscle in the front of your neck – just grab a handful & pinch between thumb & fingers. VERY good book on this is the Trigger Point Therapy Workbook by Clair Davies.
