Chest tightness for week.normal ekg other than my regular inverted twaves. seems like may be worse on empty stomach and sometimes pain under right rib?

Other symptoms?: If you are having only intermittent chest discomfort, not related to exertion, it may be musculoskeletal. Changes with your meal pattern may point to a gastrointestinal cause. If you have risk factors like diabetes, smoking, high cholesterol or hypertension, your overall risk is increased, however it is best to have your doctor examine you to determine if your need any further testing.
