A trigger point is an area of hyper-irritability within soft tissue structures. It is characterized by local tenderness and sometimes referred. These referred sensations can include pain, tingling, numbness, burning or itching. Some trigger points are just localized. After locating the trigger point or points, the therapist will use several different finger techniques of varying pressure on and around the points in order to break down the build-up of the knot. Depending on the size of the trigger point, it may take several visits to the therapist in order to be assured that the entire trigger point has been deactivated.
