Acute pharyngitis and chronic pharyngitis have fundamental differences, primarily in the nature of the diseases. Acute pharyngitis is acute, while chronic pharyngitis is chronic. Due to the different nature of the diseases, the clinical symptoms of acute and chronic pharyngitis also differ. Acute pharyngitis typically presents clinically with throat pain, whereas chronic pharyngitis usually manifests as dryness, itchiness in the throat, or a sensation of a foreign body in the throat, among other discomforts. Additionally, their treatments are different. For acute pharyngitis, antibiotics may be used if there is purulent sputum or a bacterial infection. In contrast, chronic pharyngitis generally does not involve the use of antibiotics; instead, treatment mainly consists of taking Chinese patent medicines that clear heat and detoxify the body. Thus, the differences between them are quite distinct. (Please consult a professional physician before using any medication; do not self-medicate.)
