In costochondritis, there is inflammation in either the costochondral, the costosternal or the costoclavicular joints (or a combination). Costochondritis causes chest pain, felt at the front of the chest. The pain is typically sharp and stabbing and is worse with movement, exertion and deep breathing. Pressure over the affected area also causes sharp pain. The pain is usually confined to a small area but it can spread (radiate) to a wider area.
