The sternalis muscle is a little known muscle located at the sternum. This muscle seems to be vestigial in that it doesn’t have a known function. In originates on the superior portion of the sternum and the upper part of the pectoralis muscle. It’s insertion is the cartilage of ribs 3-7, or sometimes the sheath of the rectus abdominis, or the lower part of pectoralis major. Even though this muscle doesn’t seem to have a purpose anymore it can still harbour trigger points. These points will cause pain to be felt intensely deep in the sternum, with spillover pain radiating down the inside of the arm.
The supraspinatus muscle is one of the muscles that makes up your rotator cuff. It attaches from the scapula to the humerus. It functions mainly to laterally rotate the arm as well as stabilize the shoulder joint. It also assists in abduction of the arm. This muscle can often harbour stubborn trigger points. These points refer pain into the shoulder, down the arm, into the elbow, and even into the forearm if irritated enough. These points can be effectively treated with trigger point massage therapy.
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.
People often think of a massage as a relaxing experience, something they might do occasionally, or give as a gift along with a trip to the spa. Trigger point massage therapy is another kind of massage used to treat pain and physical dysfunction. Trigger points can develop in people from all walks of life. They can affect people of all ages, office workers and labourers, elite and weekend athletes, post surgical patients, people with acute pain from injury and people with chronic pain. Trigger point massage therapy can treat a wide variety of physical conditions such as:
– back pain.
– Carple tunnel syndrome
– achy persistent pain
– pain from Fibromyalgia
– post surgical pain and scarring
– soft tissue injuries related to sports
– TMJ dysfunction
One of the most common causes of achy restless shoulder blades is trigger points in the rhomboid muscles. these muscles are responsible for pulling your shoulder blades back, and are often overloaded from poor shoulder posture. These muscles are very common areas to develop trigger points. Once there they will produce a persistent deep achy pain along the inside of the shoulder blade.
The trapezius muscle or traps is a large diamond shaped muscle located in your back and neck. It is responsible for both neck and shoulder movements as well as stabilizing these areas. Because of this the traps are a very common muscle to become overloaded and strained. When this happens trigger points form in the muscle and cause pain, refered pain, stiffness, and weakness. The upper portion of the muscle is the most common area in the body to develop trigger points. These points refer pain up the neck, behind the ear, and into the temple causing headaches. Trigger points in the lower parts of the muscle will cause shoulder and upper back pain. Trigger points need direct attention to be treated. Otherwise they can out live you!
