Pharyngitis can cause chest tightness and shortness of breath. Pharyngitis can generally be divided into acute pharyngitis and chronic pharyngitis. Acute pharyngitis can also be divided into acute simple pharyngitis, acute necrotizing pharyngitis, and acute edematous pharyngitis. Simple pharyngitis is the most common, and the latter two are rare, but both are dangerous. If the condition of acute necrotizing pharyngitis is not controlled, the soft palate may be necrotic and perforated; Acute laryngitis, hoarseness and dyspnea may occur when the throat is invaded. Acute edematous pharyngitis mainly involves the soft palate, tonsil area and throat entrance. Pharyngeal mucosa edema occurs rapidly, which is grayish white, translucent and uplifted, without inflammation. At the beginning of the disease, the patient felt that there was a foreign body in the pharynx, and then dysphagia and dyspnea quickly occurred. In serious cases, the throat entrance was blocked, and asphyxia occurred.
