Pharyngitis is a common and frequently occurring disease in daily life, divided into acute pharyngitis and chronic pharyngitis. Patients with acute pharyngitis experience sudden onset, often due to bacterial infection, or triggered by exposure to cold or a cold. The patient's throat will exhibit acute congestion and inflammation, with symptoms primarily including sore throat, dry throat, and a sensation of a foreign body in the throat. Usually, after symptomatic treatments such as anti-inflammation, throat clearing, and unblocking orifices, the patient's symptoms can generally be relieved within 5-7 days. On the other hand, patients with chronic pharyngitis are mainly treated through daily protection, avoiding excessive use of the voice, and a comprehensive treatment method that includes quitting smoking and alcohol.
