Three days, cough, no phlegm, no fever For several days, what should I do

Patient's question:

Three days, cough, no phlegm, no fever

Doctor's answer:

A cough without phlegm or with very little phlegm is called a dry cough, also known as a dry cough. It is commonly seen in the initial stages of acute pharyngitis, acute tracheitis, pleurisy, and mild pulmonary tuberculosis. Currently, over-the-counter medications for treating dry cough include expectorants like Pholcodine, Mekotuss, Cough Quick, and Compound Licorice Tablets.
