What causes sudden cough with lung odor?
Patient: I recently smelled a strange odor coming from my lungs/bronchial tube after a sudden cough.  It was not an extended cough more of a sudden clearing hack.  The smell lasted about 10 minutes and was sweet and kinda chemically.  Should I be worried?  I don't and have never smoked though have been around smokers alot. Doctor: Thanks for your question on Healthcare Magic.I can understand your concern. No need to worry for single episode of this kind of sudden cough with sweet smelling expectoration. Do fresh air inhalation, warm water gargles etc. But if such episodes are recurrent then better to consult pulmonologist and get done clinical examination of respiratory system and chest x ray to rule out lung infection.Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
