While the scar tissue itself is not painful, it does tend to limit range of motion, and the ongoing stiffness may contribute to chronic pain. 2.Apply oil to the area of the body that is being treated. 3.Angle the tool at 45 degrees in the direction that you want to treat. 4.Press the tool onto the body with smooth, firm strokes in one direction. 5.We recommend two to three physical therapy treatments per week over a span of four to five weeks.
