The differences between acute and chronic pharyngitis are quite distinct. Acute pharyngitis comes on suddenly, and patients typically experience sudden high fever, severe throat pain, along with symptoms like dizziness, headache, cough, and nasal congestion. Examination may reveal swelling and prominent congestion in the soft palate and uvula, and yellowish secretions on the pharyngeal walls. In contrast, chronic pharyngitis primarily presents with localized symptoms and lacks systemic symptoms. Patients may experience dryness, pain, itchiness in the throat, sensations of a foreign body or obstruction, burning sensation, and irritative cough. In terms of treatment, acute pharyngitis initially requires a routine blood test to determine whether the infection is bacterial or viral, and symptomatic treatment can then lead to recovery. Chronic pharyngitis mainly requires the management of gastrointestinal function, along with a mild diet avoiding spicy and irritating foods, physical exercise, and avoiding colds. Additionally, nebulized inhalation can be used to alleviate local congestion and edema, gradually relieving symptoms and preventing recurrence.
