I have done the antibiotics course of 5 days in the start of Sep 2020 month for white sores I got on 1 of my tonsils. Gargling with betadine medicine is going on everyday. Still it didn't go totally.I consulted ENT doctor 10days before, he removed it by applying some medicine as that sore became so thick and suggested me to gargle every time after I eat my meal for next  whole week. However what I observed is even I miss to gargle once/twice a day in between, new white sore comes on the same tonsil next day. It does not pain but gives little prickly feeling in throat. I am facing this issue since a month now and no idea on what to do next.. please help.
