Relatively easy. Acute pharyngitis is an acute inflammatory disease of the pharyngeal mucosa, and acute pharyngitis can also be part of an upper respiratory tract infection. Clinically, the main manifestations of acute pharyngitis are pain in the throat, and severe cases may exhibit symptoms like chills and fever. We can observe that the mucous membrane of the throat is highly congested, and there may even be purulent secretions. After treating acute pharyngitis clinically, it is relatively easy for it to recur. This is because our usual diet of spicy and irritating foods, or foods that are too cold or too hot, can adversely stimulate the mucous membrane of the throat. At the same time, if we are prone to catching colds, the cold itself will affect the mucous membrane of the pharynx, thus making acute pharyngitis clinically prone to recurrence.
