Coughing for half a month, usually severe at night, how to deal with it?

Patient's question:

Coughed for half a month, usually coughs badly at night, sometimes causes dry cough. Took medicine for about 10 days, but the drip still hasn't improved. 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 is usually rich in normal flora, and if we regularly eat the aforementioned foods, the microorganisms that prefer these foods will become highly adapted. When these microorganisms disrupt their balance, the dominant ones will cause trouble, leading to illness or throat inflammation in the human body. Mild cases may initially only cause a cough, but later develop into throat inflammation or other conditions such as fever.
