<s>[INST] Hello Doctor, I started with cough without cold or flu soon after Christmas and when doctor checked she said I have lung infection and was given antibiotics for a week. I faithfully completely the dosage last month but still continues with dry cough. Then the doctor checked and said my lungs are clear and said the cough will go but gave me Apo-Mometasone nasal spray but its now 5 days but still I get dry cough and feel like phlegm stuck in the throat. I also take Benilyn dry cough syrup but the cough is still there although it has reduced. Can you please advise if this cough is dangerous. [/INST] Hello, I advise you to have a chest x-ray so that the things will be more clear. You might have some kind of allergic cough which takes some time to stop completely. You can continue to use the cough syrup. Use APO mometasone if you have nasal problems also like cold or frequent sneezing. Better let's have a consult with a respiratory physician to have complete and thorough checkups followed by correct treatment. Take care. Thank you. </s>
