Hello. I was exposed to an exploding tire in October of last year and have experienced a ringing in one ear as well as a full feeling in that ear with very mild hearing loss. Three general practioners examined it and told me I had a small amount of fluid behind my eardrum that needed to be drained. Today, I saw an (elderly) ENT specialist and he told me there was no evidence of fluid and that the situation was more than likely permanent. Is it worth seeking a second opinion?
