I am having the same problem. I have had ear pain and ear problems pretty much all my life. Had ear tubes when I was a child and everything. Been to numerous doctors about awful ear pain, and so much dizziness that I cant walk straight at times, and so bad at times that I run into things, and they said just an ear infection, or nothing was wrong. Finally found a ENT doctor, and he looked in my ears for a bit and finally found out that my ear drums were deformed. They are sucked in so far into my ear that I am having ear surgery next month to have reconstructive inner ear surgery. Because they are sucked in so far, they created pockets inside and fluid and stuff has caused horrible pain, and made it diseased so they have to remove all of it now, because my estheshia tubes havent been draining properly either. Gross I know..
It has taken years and years of different doctors to finally diagnose it.
So dont give up, you know how your body is, so dont let them tell you nothing is wrong. Be persistant.
Ask them to take a closer look at your ear drums. Hopefully if something is wrong they can take care of it. May just need ear tubes to fix it.
Hope that all works out, but keep switching doctors until you get an answer.
