I Recently Had Tonsillitis Which Got Better In Its Own,

I recently had tonsillitis which got better in its own, ( the white spots went away) once that was gone my throat was still sore and feels like I have blisters at the back of my tongue, I can't see any thing but I can feel them with me tongue, I also had a bit of ear pain when I had tonsillitis and one of my ear felt congested
