I take prevacid for my indigestion. Today I woke up with it. And when I take a deep breathe it hurts right in the middle of my chest. It could be that I ate at KFC early. I have had ultrasounds of my heart and EKGs done but I am still worried it could be my heart. I am only 21, but has any body else experienced pains taking deep breathes with indigestion? and can you have indigestion all day long? Chest pains all day long?
