The small lump under the chin is most likely a reactive lymph node from a throat, tonsil, ear or dental infection. Ear pain can also be referred from an inflamed throat
Next Steps
Please visit an ENT specialist or physician within 24 hours for examination of the ear, tonsils, teeth and lump. Do not squeeze it or start antibiotics without examination. Use warm fluids, salt-water gargles and paracetamol if needed
Health Tips
Go to the emergency department immediately for difficulty breathing or swallowing liquids, drooling, muffled voice, inability to open the mouth, high fever or rapidly increasing neck swelling—these may indicate a deeper throat infection.
if the lump persists beyond 2–3 weeks, enlarges, or becomes hard and fixed, it requires further assessment.
