thanks or asking your query I completely understand your problem the most common cause of pain over that reason in young age group is peptic ulcer disease and much more commoner in smokers and people who take alcohol . if u r a smoker u should first quit smoking and drinking alcohol ,this will help u a lot with your pain .as for medications u can take a proton pump inhibitor like pantoprazole by asking your physician. if u r more worried about heart issues u can get an ecg done and consult a general physician after which u will feel relieved. thanks/regards feel free to ask more questions may god bless u a healthy life
