Ear fluttering. And what is happening?

I got my left side upper and lower wosdom tooth removed 4 months ago and after that i havea fluttering like sensetion(like vibration of my ear drum ) in my left ear when 1) I rub my ear pinna (The fluttering happens momentarily and stops) 2)When i talk loud (same happens momentarily and stops) 3)when kitchen utensils fall 4) when i clap in front of eae I took anti allergic ,nasal spray but it didnt imporove. I told my dentist that it is happening after wisdom tooth removal only but he denies that it is not related to the extraction. my dentist gave a lot of pressure during extraction and my mouth was wide open for atleast an hour. I am very much tensed because it is already 4 months . What to do and what is happening?
