The clinical symptoms of chronic pharyngitis are common as follows. First, there is a foreign body sensation, sometimes vomiting can not be spit out, swallowing can not be swallowed, the throat is dry and itchy, burning, slight pain, etc. Second, is the secretion sometimes more, sometimes less, but more viscous, often attached to the back wall of the throat, resulting in constant throat clearing. Third, it is the inflammation or secretion that leads to irritating dry cough, and to vomit when you get up in the morning to brush your teeth or when you clear your phlegm. These symptoms are easy to happen when the climate is dry, when the air is more polluted, and when there is more talking. When we look in the mirror, the mucous membrane of the throat is generally dark red, diffuse and congested, with a small amount of sticky secretions attached to the posterior pharyngeal wall. In hypertrophic pharyngitis, the lymphatic follicles of the posterior pharyngeal wall can be seen with the naked eye, along with congestion and swelling, as well as granular protrusions that fuse into a mass, and longitudinal cords on both sides of the posterior pharyngeal wall, which constitute the manifestations of pharyngitis.
