Re: My heart hurts when I cough.
Your heart is very protected behind your breastbone. You probably have bruising on the breastbone, and that would definitely hurt when you cough. if your heart was damaged, it would not take coughing to hurt it, it would be obvious all the time (breathless, sweaty etc). If you are otherwise on your feet and functioning, then I would say it is not serious. Take some pain killers and rest. If it gets worse or you get any of the other symptoms, then go to the ER.
