24. Tietze Syndrome
Tietze syndrome is an inflammatory syndrome that causes swelling in the cartilage of the upper ribs. This can result in a lot of chest pain that can be debilitating. The syndrome usually affects only one rib, so pain is usually only on one side of the chest. This pain can radiate up the neck, shoulders, and arms. When this happens, the area can feel a bit warm to the touch.

The pain can range from mild to severe but does make it difficult for a person to cough, sneeze, perform quick movements that involve the upper torso, or exercise. The syndrome seems to have an alternating pattern of having no symptoms and then symptoms flaring up. It’s unclear what causes the syndrome, but scientists believe that microtrauma to the chest could play a part in the syndrome appearing.
