Since you have consulted multiple times. We need to investigate to know the cause of the cough.
I would advice doing CBC, ESR,
CRP, Xray Chest, etc.
In case of sputum in cough, you need to do sputum culture and CBNAAT.
The most probable case of dry cough is COPD, and of cough with expectoration is TB.
So i would advice you to take the necessary action soon and consult me online on Practo.
