Chest pain: Have you done any heavy lifting or repetitive motion with your arms recently? If you get swelling in the muscles that hold your ribs this can cause chest pain. You can apply moist heat to the area and take an anti inflammatory medication such as Advil (ibuprofen). If it last more than a few days of gets worse you need to go to the ER.
