Acute pharyngitis is caused by the invasion of bacteria or viruses due to weakened immunity and resistance in the body, leading to systemic symptoms and symptoms in the throat area. Patients may experience sudden high fever, with body temperature above 38.5°C, dizziness, headache, dryness and pain in the throat, as well as a sensation of obstruction and foreign body in the throat. Examination may reveal significant congestion and swelling in the throat, with yellow secretions adhering to the soft palate and pharyngeal wall. For treatment, patients initially need a complete blood count test; if there is an increase in white blood cells, oral antibiotics such as cefixime and amoxicillin are needed. If lymphocytes are elevated, oral administration of ribavirin granules is required, which has good effects. Nebulization can also be used concurrently to alleviate local congestion and swelling, and recovery can generally begin within about a week. Note: Medications should be used under the guidance of a doctor.
