Costochondritis is a less common cause of chest pain in adults but one that occurs fairly frequently in people who have had cardiac surgery. The diagnosis can only be reached after excluding more serious causes of chest pain that are related to the heart and lungs.
The appropriate studies, such as ECG, chest x-rays, blood test for heart damage (cardiac enzymes and troponin levels), and other studies will be done as indicated. In cases of possible infection, the white blood cell count may be elevated. Any chest pain in adults is taken seriously and not ignored. If you are concerned, consult with your doctor.
