Extensive research into Trigger points shows that pain has a characteristic referred pain pattern, meaning that the site of your pain is usually NOT the primary source. With knowledge of Janet Travell's Pain Maps the therapist treats the full length of all the muscles around the affected joint for trigger points.
Communication is absolutely key to finding and releasing the specific trigger points contributing to your pain. Although these techniques can be intense they should never be painful as this could cause further trauma to the already dysfunctional muscles. Using a pain scale of 1-10 the therapist always works below the client's pain threshold using static compression to release trigger points. Some are certainly to be more stubborn than others so a series of treatments is usually required for lasting results.
