How old are you? Have you ever been diagnosed with digestive ulcer? Do you have any risk factor for coronary heart disease (heart attack), such as, hypertension, diabetes, smoking, family history, et al? When does the chest happen usually? Is it related to physical exercise? How long does it last? Do you have a feeling of sudden death, or chest tightness? I am not sure about your situation. If you have very uncomfortable feelings , you should still go to the ER to find out.
