Postnasal Drip Cough is a common condition where mucus accumulates in the back of the throat, leading to persistent coughing. In this comprehensive guide, we will break down the different aspects of Postnasal Drip Cough in simple language to help you better understand its types, causes, symptoms, diagnostic tests, treatments, drugs, and potential surgeries.
Types of Postnasal Drip Cough:
There are two main types of Postnasal Drip Cough:
