@Robert44 the exact same thing is happening to me right now, I have my left ear infected, since last week, I hear muffled sounds as if I'm underwater (btw that's because you do have fluids in the inner ear) I even perforated my eardrum (blood and pain), the worst part is that in that ear, I already had T and now it's worse, but my right ear has a significant hearing loss due to an old accident when I was a kid (also perforated eardrums involved) apparently I have vulnerable ears, I am super careful with my ears, I avoid loud environments, don't longer listen to music with earbuds, and if I have to, I play it very low, I avoid pools, and still, got sick of the ear.

my advice, is to keep on your Amox treatment, stop taking NSAID pain killers, like Aspirin or Ibuprofen, get Sudafed for the congestion, keep going to your ENT and last but not least, keep writing here, or read around here, it helps me in the mean time. My doctor told me I'm supposed to get my hearing back once the ears heal completely, that takes weeks or even months. So hang in there and stay calm, use a Tinnitus Masker (there's tons of apps for smartphones) keep us posted

Best of luck.
