Pain in the necks

I could always feel the postural pain and stress in the back of my neck but the front of my neck was always just there unless I cut it shaving. It now feels to me the back of the neck is a reflection of the anterior neck musculature along with spinal postural issues. The use of my left anterior neck and under chin is not symmetrical with the right. My left side feels more contracted giving the right side a little more play in communication.  The contracting is the easy part the relaxing in a functional way is the more difficult. Feeling some of the smaller musculature relax and lengthen as I attempt to use the left tongue is immediately reflected in the back of my neck.
