How old are you? Do you have high blood pressure? What is the intensity and duration of the pain?
Chest pain can be mild or even life-threatening. For example, conditions like a heart attack and aortic dissection would cause life-threatening chest pain. Chest pain can also be caused by mild conditions, such as rib bruise or pleurisy. So if the pain is severe and does not go away, you need to go to the ER.
