Hi, I suffer tinnitus and daily my left blocks. It was going on for a few years. It was uncomfortable. Sometimes a netti pot would unplug it right away. I went to an ENT and he put a tiny scope up my nose into my throat right in the office. Very quick procedure. He did it up each nostril. He found the blocked ear had a eustachian tube flap that was sticking. I had a balloon procedure done and it worked. It may last 6 months or a few years, no guarantee. It was a very fast procedure. It’s similar to scheduling an endoscopy. I think it lasted 15-20 minutes. You can google it or find the balloon procedure on utube and watch it. That’s my story. Not sure what your diagnosis will be. Their was no reason why it happened to me or if related to tinnitus but it’s better not feeling like I live under the sea every day.
Blessings
