Pain in the chest wall around the breastbone (or sternum) is the most characteristic feature of the condition known as costochondritis. Medically, the term chondritis refers to inflammation of any cartilage in the body. Costochondritis refers specifically to inflammation of the cartilage that joins the ribs to the breastbone (called costal cartilages). The chest pain of costochondritis sometimes is severe.
Costochondritis usually, but not always, involves one side of the breastbone. Sometimes the pain can extend to the shoulder or arm on the involved side. When costochondritis is accompanied by swelling of the areas surrounding the cartilage, the condition is called Tietze syndrome. In Tietze syndrome, the swollen area of the inflamed cartilage may be tender to the touch, and the skin overlying the cartilage may be reddened.
Costochondritis is most common in people between 20 and 40 years of age. In most cases, doctors do not know why the condition develops. Trauma to the chest wall may lead to costochondritis, and it also is believed that viral infections, particularly upper respiratory infections, may cause costochondritis. The condition also can occur as a feature of more generalized diseases of inflammation such as certain forms of arthritis, fibromyalgia, and inflammatory bowel disease.
