I had my tonsils taken out last january due to excessive tonsillitis. Although, for the most part, my throat has been feeling much better, my right ear still feels very muffled, almost like there's something in it. It get worse when my tongue touches the back of the right side of my throat, which leads me to believe that the problem is connected to my throat. There is also a small white bump on the soft palate of my right side - I can see it when I look under the light in the mirror. I've also been having very dry mouth lately, especially in the morning, with a lot of mucus. By mid-day it's usually fine.

Any idea what this could be? Should I go see my ent again?
