Costochondritis (kos-toe-kon-DRY-tis) is an inflammation of the cartilage that connects a rib to the breastbone (sternum). Pain caused by costochondritis might mimic that of a heart attack or other heart conditions.

Costochondritis is sometimes known as chest wall pain, costosternal syndrome or costosternal chondrodynia. Sometimes, swelling accompanies the pain (Tietze syndrome).

Costochondritis usually has no apparent cause. Treatment focuses on easing your pain while you wait for the condition to improve on its own, which can take several weeks or longer.

Costochondritis usually goes away on its own, although it might last for several weeks or longer. Treatment focuses on pain relief.
