For about a year and a half I have been getting mild, to sometimes moderate chest pain. Went to ER 3 times and ekgs were always good. Whats wrong?

Sched appt w/ Dr. Chest pains can be caused by many things besides the heart. Ekg's can miss problems if it is intermittent. You should schedule a real appointment with a doctor. The emergency room is not the place to go to figure out a chronic problem. Their job is to take care of acute problems (emergencies). You need someone who can follow up and get a detailed and accurate picture of what's going on.
