Chest wall pain
Your health care provider can diagnose costochondritis by pressing on the area where the ribs meet the chest bone (sternum). If this area is tender and sore, costochondritis is the most likely cause of your chest pain. However, your doctor should make this diagnosis only after speaking with you and examining you.
