Suggest Treatment For Reoccurring Tonsillitis

I have had reoccurring tonsillitis. It never goes away. After being on 7 antibiotics nothing completely is getting rid of it; therefore, 3 days after being of antibiotic it comes back full force. The tonsillitis almost disappears completely within 1 day of antibiotic except down my throat. It then creeps back in after that 3 day margin. What are my options?
