The weather is dry and I have a bad cough.

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.
