Everything in the body is connected, so a hypertonic muscle that is causing pain in the neck may be a result of a muscle imbalance in the hip. The source of the problem must be treated for one to truly get out of muscle pain. Muscles have a tendency to fight over joints. When one muscle group is out of balance it will cause another muscle group to be out of balance as well. Also, the soft tissue pain that you are experiencing now may be the result of an injury that has happened many years ago. In situations like the ones explained above, the injury did not occur overnight. Often times it will take more than one session to reprogram the muscles to lengthen.
