Are you experiencing a burning feeling in your chest? It might be heartburn, but it could also be caused by reduced blood flow to your heart (angina) or even an actual heart attack. The signs of a heart attack, angina, and heartburn can seem very similar. Even doctors can find it hard to tell the difference just by checking you and asking about your health history. That’s why if you go to the emergency room because of chest pain, they will run tests immediately to ensure it’s not a heart attack. So, how can you tell if it’s one problem or the other?
