Why Do Tonsils Suddenly Become Inflamed—and What Should You Do?

Acute tonsillitis is typically caused by infection and is usually treated with anti-infective medications. First, maintain good oral hygiene by brushing teeth daily. Penicillin-based antibiotics may be prescribed for anti-infective therapy, alongside regular physical exercise. Surgical removal (tonsillectomy) may be indicated if the tonsils are excessively enlarged and impair swallowing. If symptoms worsen, antibiotic therapy is required to combat infection—this may be administered either orally or intravenously—to alleviate pharyngeal symptoms.
