Chest Wall Pain

The chest wall is composed of skin, subcutaneous tissue. muscles, bones that make up the rib cage and fascia of the anterolateral aspects of the thorax. The same structures that lie posteriorly (towards the back) are considered as part of the back and not as the chest wall. Within the wall lies a number of nerves, blood and lymphatic vessels, cartilage and joints.

The structure of the chest wall allows it to be flexible so that it expands and contracts during breathing and absorbs the force of a blow. At the same time, it is rigid enough not to collapse due to the negative pressure within the pleural cavities, support the upper limbs, neck and head, protect the inner organs of the thorax and serves as a point of attachment for a number of muscles of the upper limb.

Considering the number of parts of the chest wall, its complex structure and diverse functions, the chest wall is prone to a number of pathologies that can result in pain.
