The weather turns cold, and the cough is dry.

If there are follicles in the pharynx, it is generally chronic hypertrophic pharyngitis, which is more serious. If there are many follicles, I suggest you go to the hospital to eliminate them by laser or freezing, and then take sustained-release citrulline or traditional Chinese medicine for consolidation treatment after operation. If there are not many follicles, gargle with light salt water every morning and evening, and take sustained-release citrulline every day.
