I have many ear problems as well. Luckily, mine were discovered by a neurotologist at Mayo. I had similar symptoms to you, but I had a Cholesteatoma. It caused all kinds of problems with my ear, but was not visible to the eye. So I had to have many scans to find it. I had a successful surgery in 2016 that corrected it. Is not perfect, but much better than it used to be.
