Common sense : If the symptoms are gone, it's probably not your heart, which would be unlikely in a 21 year old that is otherwise healthy. Could be a muscle spasm or pleurisy, especially if it was worse with a deep breath. Those are not dangerous. If it comes back or is progressive, i would consider the er, but in the end, you have to make the call. This forum is not equipped for that type of advice.
