Hello, As your ENT specialist has diagnosed the cause pain as swelling of tonsils alone,i suspect impacted wisdom tooth is present in your oral cavity which is inflammed. The above mentioned symptoms are usually associated with pericoronitis. Please do visit a dentist and get a thorough evaluation done. Meanwhile,maintain oral hygiene well. Gargle frequently with warm saline and betadine. Rinse your mouth after every meals. The pain will subside once the tooth has removed or flap overlying tooth has incised out. Hope this helps.
