Time to see doctor: Chest pain is a sign that she should talk with her doctor, or go to an ER if pain is moderate or worse. In young adults, chest pain is less likely a heart attack. She should not drive (get a ride, or go by ambulance). Even if it turns out not to be costochondritis, myocarditis, anxiety attack symptoms, or heart attack, the ER will also have checked for problems like a collapsed lung or pneumonia.
