<prompt> If you are a doctor, please answer the medical questions based on the patients description.I m just getting over either bronchitis or bacterial pneumonia didn t get the chest xray. It s been 2 weeks. still coughing...chest really tight...but sorta feels like heart burn...feels like I ve inhaled hot smoke but I haven t...never smoked ever. Is it heartburn or is it part of the respiratory infection?  <response>: Respected user, HiT hanks for using Chat Doctor.come have evaluated your query thoroughly. Recurrent cough may be due to - Improperly treated previous infection - resistant bacteria - poor host immunity - continuous external exposure to irritants - others. To differentiate it from heart burn and respiratory infection need thorough history , physical examination, co relation with reports. Hope this clears your query. Welcome for further assistance. Regards.
