Coughing for half a month, usually severe at night, how to solve it

Patient's question:

Coughed for half a month, usually severe at night, sometimes causing dry cough. Treated for 10 days, but the intravenous drip still hasn't shown any improvement. What kind of help is needed: The best current treatment method

Doctor's answer:

It might be a cough caused by pharyngitis. Pharyngitis is commonly found in people who frequently consume snacks, sweets, fried foods, beverages, cold drinks, and dairy products, because these snacks tend to adhere to the throat and serve as a good medium for various microorganisms. The oral mucosa normally harbors a large number of normal flora. If we frequently eat the aforementioned foods, the microorganisms that thrive on these foods will become highly adapted. When these microorganisms disrupt their balance, the dominant ones will cause harm, leading to illness or pharyngitis in the human body. Mild cases may initially only cause a cough, but later develop into pharyngitis or other conditions such as fever.
