A trigger point is a hyperirritable area usually found in a band of tight muscle or fascia commonly referred to as a “knot”.  These points can be tender when touched and may refer pain to specific areas elsewhere in the body.  A trigger point may also affect the strength and length of a muscle, and which in turn limits your flexibility.  Trigger point therapy reduces the pain of the point, sickness and the referring pain.  It is a highly effective technique to eliminate and treat headaches, as tension headaches are often a result of trigger points in the neck and shoulders.  Trigger point therapy seeks first to identify trigger points, and then apply steady, appropriate pressure to the point to release it.  This is usually followed by massage to the surrounding area to help treat the cause of the trigger point.
