Hello, I understand your concern. With reference to your query regarding the cough that you are associated with, let me clarify certain details about cough. Cough is only a symptom not a disease where your body's way of removing foreign material or mucous from the lungs and upper airway passages of reacting to an irritated airway. Cough may be productive or non productive. If it is productive, it produces phlegm or mucous which may be due to viral (especially when you have cold), infections like pneumonia, bronchitis, sinusitis, or TB or COPD, or GERD or Nasal discharge (Postnasal drip) and lastly due to smoking or often tobacco use; whereas Non productive cough is mainly due to viral illness (after a common cold), Bronchospasm, Allergies (allergic sinusitis), medicines used in high blood pressure, or asthma or blockage of airway. If it is due to viral, antibiotics should not be used because it will alter the cause of viral infections and also exposes you to the risk of an allergic reaction. Usually cough occurs with bacterial or viral respiratory infections. So it is better you get it checked from your GP in detail about the cause and get relief from it. Thank you.
