A very common muscle to become overloaded and damaged, and thus develop trigger points, is the pectoralis major muscle. This is the muscle that makes up the chest. It’s main functions are adduction and internal rotation at the shoulder. Poor rounded shoulder posture is a common cause of pec tightness and trigger points. trigger points in this muscle will produce pain felt into the front of the shoulder, the chest, and down the medial arm. If these symptoms occur in the left pec it can mimick heart pain. In women, these points can be a cause of breast pain and nipple hypersensitivity.
The subscapularis muscle is one of the rotator cuff muscles. It is located on the inside of the scapula, and can be difficult to access. This muscle functions to internally rotate the arm as well as to adduct the shoulder. It is also a stabilizer of the shoulder joint. When this muscle is overloaded or injured trigger points can form. These points will refer pain into the back of the shoulder and down the inside of the arm to the wrist. Trigger points in the subscapularis are often associated with a frozen shoulder.
The Brachioradialis muscle is located in the forearm. It is responsible for flexing the elbow in semipronation such as when lifting a coffee mug up to your mouth. Trigger points in this muscle are an often overlooked source of elbow pain. These points will also refer pain down the forearm and into the web of the thumb.
The trapezius muscle is a large diamond shaped muscle in your upper and middle back and neck. It it responsible for both shoulder and neck movements. Trigger points in the upper portion of this muscle are the most common points to develop in the body. These trigger points most often occur due to poor posture, such as a slumped sitting posture. Trigger points in the upper portion of the traps will cause pain to refer into the neck, head, and into the temple. These points are one of the most common causes of headaches.
Myofascial trigger points are contracted knots in muscle tissue. They are one of the most common causes of pain in the body. Most people will experience pain from trigger points at some point in there lives. Trigger point pain is usually felt as a deep achey pain. This pain may be refered In a specific pattern to other areas of the body. For example, trigger points in your hip can refer pain all the way down the leg into the foot. Trigger points will also mimick joint pain leading to misdiagnosis of arthritis. Trigger point massage therapy targets the knots specifically with focused deep work to release the area and allow the muscle to heal.

The gluteus minimus muscle is located at the hip. It functions to abduct the hip and stabilize the pelvis. Trigger points commonly develop in this muscle from overload stress. The referral pattern of these trigger points will refer pain down the side of the leg, as well as into the glute and hamstring. These symptoms are often mistaken for irritation of the sciatic nerve called ” sciatica” which produces very similar symptoms.
The gluteus medius muscle is a mover and stabilizer of the hip. As a result this muscle is commonly overloaded and harbors trigger points. These trigger points can refer pain deep into the s.i. joint as well as into the low back and hip. Once developed, trigger points will not release on their own. A manual intervention such as trigger point massage therapy is needed to treat the area.
The multifidus muscle is a long muscle that travels the length of the spine. It has different actions on different parts of the spine. It extends and laterally flexes the cervical and lumbar spine, and rotates the thoracic spine. Trigger points in this muscle are common due to poor posture and bad movement mechanics. Trigger points in the lumbar area area are a common cause of low back pain. These lower points can also refer into the abdomen. Points that form in the cervical region will refer pain down the neck into the shoulder blade area.
Over 2000 published research studies demonstrate:
• Laser therapy improves blood flow and lymphatic drainage
• Laser therapy has a strengthening effect on tissue repair
• It is an effective means of relief for many pain syndromes
• It can improve immune response
• Enhanced nerve regeneration & function
• Increased microcirculation & vasodilation
• Increased lymphatic flow
• Increased collagen production
• Increases the speed, quality and tensile strength of tissue repair
• Reduced inflammation
• Enhanced angiogenesis (creation of new blood vessels)

Myofascial trigger points form in a muscle due to overload stress. A portion of muscle fibers lock up into a knot. Once formed these points will irritate sensory nerves that are in proximity to the knot. When this happens,
trigger points have the capacity to refer pain along specific distributions or patterns that are well mapped out. sometimes pain may be felt at a great distance away from the actual point itself.
