See your doctor. Your symptoms certainly sound like "heart burn" or gerd (gastroesophogeal reflux disease), but depending on weight, family history, other med problems, etc, you can never be too sure it is not cardiac as well. Certainly try to avoid trigger foods for gerd (acidy, spicey, fatty foods, etc) and increase fiber and fruits. To assure it is not your heart however, see a doctor.(meds may be needed too).
