Ok my first post here so I apologize if there are other threads with a similar topic... About 6 months ago I started noticing a sensation in just one of my ears. It feels like my ear drum pulsing in and out...just once. It happens almost always when it is completely silent and then there is one sharp sound. If there is background noise, it doesn't happen, or I don't notice it at least. I've noticed it progressing and happening now sometimes even when I make a sound with my voice when it is otherwise quiet. It makes a low thumping sound and a sensation of my eardrum moving in and out, just once. I went to an ENT and they found very little hearing loss in that ear and they diagnosed the eardrum to be healthy as well as the ear muscles that tense up when you hear a loud sound. Some other tidbits....I notice it more in the morning where I had salt the night before, presumably from added pressure and fluid. I also notice occasionally when running a clicking sound from that ear. I can go in for more tests but I'm hoping it may go away on it's own from switching back to a predominantly vegan diet with lots of fruits and vegetables. I noticed that diet healed up a lot of strange health problems over the years and I am going to try it out again on this problem. Anyone have thoughts on a potential cause?
