I have been having bad rib pain and heart burn for about 2 months what could be wrong?

Maybe diet/coughing,: It's hard to say what's wrong here, especially at your age and without obvious health factors. It could be due to diet, like spicy foods and not enough fruits and vegetables. A chest cold with a lot of coughing could explain the rib pain as can a lot of physical activity. Other than that, it seems like a temporary situation that'll get better with rest and time. If it persists, see the doctor.
