There is a fundamental difference between the two; chronic pharyngitis is a chronic inflammatory disease, while acute pharyngitis is an acute inflammatory disease. Furthermore, the symptoms of chronic pharyngitis are not very prominent in clinical settings, presenting only as a foreign body sensation or other discomforts. In contrast, the symptoms of acute pharyngitis are quite significant, such as sore throat, and may even include systemic symptoms like chills and fever. Thirdly, during examination of chronic pharyngitis, one can observe congestion of the pharyngeal mucosa, which is a type of chronic congestion. However, the congestion in acute inflammation is acute and very pronounced. There are also significant differences in treatment. For chronic inflammation, the clinical approach mainly involves administering heat-clearing and detoxifying traditional Chinese medicines, and sometimes no medication is used at all; just focus on hydrating locally without the need for any special medication. In contrast, acute pharyngitis requires medication to manage the acute inflammatory symptoms. In summary, there are fundamental differences between chronic and acute pharyngitis, whether it is in symptoms, treatment, or the pathological state of the mucosa.
