I went for a second opinion last week and this ENT basically agreed with the first diagnosis and I was getting the proper treatment. He gave me another hearing test which again was normal, but this time he found no retraction in my left ear - which is the first time it tested normal since my symptoms began. So maybe I am on the right track with the TMJ treatment. I asked why my left ear doesn't pop and he said he thought it might be anatomical. Narrower eustachian tube, less cartilidge, hard to tell exactly. He also said that ear tubes would be my decision and the risks were minimal, but they might not be a long term answer as after they come out I might be right back where I am now. I think I will live with the fullness for now and hope that the TMJ treatments provide more relief. He said it could take a long time. It's only been a month or so since I started treatment. Hope you have found relief. It is horrible feeling this way day after day, week after week.
Sorry you are having the same problems as I am, but it's good to know I am not alone or crazy. My ENT wonders why I am so bothered by these things. I just know my ears don't feel or sound right. I will continue to keep you informed of my diagnosis and treatment.
I am 29 years old and experiencing about the same thing. Or at least I think...I have no clue what it could be. The only thing I can tell ya is I think It is possible to be sinuses...If I find a cure I promise you will be the first to know. I was thinking of trying ear candleing...check it out on youtube. I have had a bunch of friends tell me they have done it and it feels great!
