What Causes Chocking Sensation In Throat Post Tonsillitis Treatment?

Hello. About 2 years ago I began feeling the sensation of something in my left tonsil. I had frequent episodes of tonsillitis over the period of a year along with a benign oral hpv wart. I saw an ENT who removed some of the debris with a suction tool and prescribed antibiotics. I also had the wart surgically removed and biopsied. The ENT also performed a larynoscopy and gave me a clean bill of health. However, I cannot to this day shale the sensationn that something is stuck in my tonsil. My tonsila are extremely wrinkly with pockets and folds. I feel thissensation constantly every time I swallow. Thoughts?
