Introduction
Sore throat accompanied by fever may result from frequent late-night activities, lack of physical exercise, habitual consumption of spicy or irritating foods, excessive mental stress, or chronic anxiety—all of which can weaken the body’s immune defenses. It may also be caused by an acute exacerbation of chronic tonsillitis. Additionally, in cases of laryngopharyngeal reflux (LPR), severe symptoms may include chills and fever.

Throat inflammation accompanied by fever may result from factors such as reduced immune resistance, chronic tonsillitis, or laryngopharyngeal reflux.

1. Reduced Immune Resistance

Regularly staying up late, insufficient physical exercise, frequent consumption of spicy or irritating foods, excessive mental stress, or chronic anxiety can all weaken the body’s immune defenses. This diminished resistance increases susceptibility to bacterial or viral infections, potentially leading to throat inflammation and fever.

2. Chronic Tonsillitis

Individuals with chronic tonsillitis are often highly sensitive to changes in ambient temperature. Fluctuations in weather or exposure to bacteria or viruses—particularly those triggering rhinitis—may precipitate an acute exacerbation of the condition, resulting in symptoms such as throat inflammation and fever.

3. Reflux Laryngopharyngitis

Common colds, consumption of spicy or irritating foods, smoking, and alcohol intake may contribute to reflux laryngopharyngitis. Typical manifestations include throat pain, dryness, and a burning sensation; in severe cases, patients may experience chills and fever.
