Although upper back pain is not as common as lower back pain but it still affects many people. Let’s first discuss what the upper back is made of. The upper back is composted of the thoracic spine. The thoracic spine consists of 12 vertebrae. These vertebrae are connected with 9 of the 12 rib bones. The breast bone is perpendicular to the thoracic spine. Rib bones are also connected to the breast bone. The thoracic cage consists of the breastbone, ribs and the thoracic spine. Thoracic means “chest” All of the upper organs are protected by the chest cage. The two major causes of neck and upper back pain or thoracic spine pain are mysofascial pain and joint dysfunctional pain. Myofasical pain is a muscular irritation. This results from muscle strains, from sports and other activities, over and under use of the muscle, sudden movements like being thrown forward in a car accident. This primarily affects the large muscles that support the shoulder blades. Joint Dysfunction is the malfunctioning of the pair of joints that connect each rib with the thoracic spine. The ribs are connected to the spine on either side by joints. Any kind of injury to one or even both joints can result in a loss of function and lots of pain.
