How can I treat a sore, inflamed throat?
Throat pain and inflammation—commonly referred to as pharyngitis—are typically caused by viral infections (e.g., rhinovirus, influenza, or Epstein–Barr virus), though bacterial pathogens like *Streptococcus pyogenes* (group A streptococcus) account for approximately 5–10% of cases in adults and up to 30% in children. Symptom onset is often abrupt and may include soreness, scratchiness, pain with swallowing (odynophagia), erythema, tonsillar exudates, tender anterior cervical lymphadenopathy, and sometimes fever.
Management begins with accurate diagnosis: clinical evaluation using validated tools such as the Centor criteria helps stratify risk for streptococcal infection. Throat swab culture remains the gold standard for confirmation, though rapid antigen detection tests (RADTs) offer high specificity and are useful when immediate antibiotic decisions are needed. Antibiotics—such as penicillin V or amoxicillin—are indicated only for confirmed or highly probable group A streptococcal pharyngitis to prevent complications like acute rheumatic fever or post-streptococcal glomerulonephritis; they confer no benefit in viral cases and contribute to antimicrobial resistance.
Supportive care forms the cornerstone of treatment for most patients. This includes adequate hydration, rest, analgesia with acetaminophen or NSAIDs (e.g., ibuprofen) for pain and fever control, and soothing measures such as warm saltwater gargles (¼–½ teaspoon of salt in 8 oz warm water), lozenges containing benzocaine or dyclonine, and humidified air. Topical corticosteroids (e.g., a single dose of oral dexamethasone) may be considered in select cases with severe symptoms to reduce inflammation and accelerate symptom resolution.
Patients should seek urgent medical evaluation if they develop signs of airway compromise (e.g., stridor, drooling, muffled voice), persistent fever beyond 3–4 days, rash suggestive of scarlet fever, neck swelling, or inability to tolerate oral intake. Recurrent or chronic throat pain warrants further investigation—including assessment for GERD, allergic rhinitis, smoking exposure, or less common causes such as malignancy or immunologic disorders.
