The symptoms of dryness and phlegm in the throat are often caused by acute and chronic inflammatory diseases of the mucous membrane of the throat. Patients may experience similar symptoms due to excessive use of voice or respiratory viral or bacterial infections, and some patients may experience pain and burning in the throat. Some patients may also experience dry throat and phlegm due to recent excessive smoking, drinking, eating spicy and stimulating food, or emotional stress, mental irritability, and other factors, which may cause the body to become inflamed. There may also be some thick secretions adhering to the mucous membrane surface of the throat, which needs to be actively treated and improved.
