Acute pharyngitis is a relatively common ENT (Ear, Nose, and Throat) disease. Whether it is severe or not depends on the extent of the inflammatory response. Generally, most patients are not too severe, mainly because it is caused by an acute bacterial or viral infection. In clinical practice, bacterial infections are more common. The main symptom is sudden throat pain. If the inflammatory response is more severe, it can cause more serious pharyngitis, which may affect swallowing and breathing, and cause edema in the mucous membrane of the throat. If it is particularly severe, fever may also occur. It is necessary to visit the ENT department to check the specific extent of infection and inflammation in the throat, conduct a routine blood test, and make a more accurate comprehensive assessment.
