Fascial Counterstrain is a therapeutic, hands-on method, designed to release spasm in all tissues of the human body. Every organ, nerve, artery, muscle, ligament, tendon, vein, and lymphatic vessel in the human body can actively spasm and produce pain in a natural, protective response to injury. Once this reflex spasm is triggered it can persist, spread and form hundreds of tender points. FCS works to release the tissue in spasm and the corresponding tender point by gently unloading the injured structure.
