hi there, your symptoms are more suggestive of a gastric reflux
then broncitis but still to put your mind to peace you can get an x-ray done and visit a physician who from your breath sounds should be able to rule out any lower respiratory infection., in the mean while continue the remedy that is giveing you relief and also take some antacids to see whether it helps you any further. You could also try some steam inhalation and cough
drops to have relief from the cough. Take care.
