I am having the same issue... My left ear is completely clogged and I cannot hear anything on that side. My right side as well is clogged but not nearly as bad as the left on top of tinnitis. I have seen an ear dr, an ENT and a hearing and balance specialist and no one can tell me what the actual problem is.. I am extremely frustrated and stressed out because I do not have any answers! My hearing test revealed 16% hearing loss on the right side and 19% on the left thus leading to an ENT reference. I've invested in hearing aids and an ID bracelet to let people know that I have difficulty hearing. I have no official diagnosis, but have been told that I have autoimmune inner ear disease, but there's no known cause other than possibly stress or the antibodies attacking my inner ear when I had a cold/flu/ allergies. The hearing and balance specialist as well checked my hearing and came up with the same results. He also hooked me up to a variety of machines to test the fluid level in my ears and said it was abnormally high-- hence the muffled sound when I'm not wearing my amps. I've already completed a z-pack which seemed to help a little, then proceeded for direct steroid injections- which was really uncomfortable! Approximately a week later I came down with a head cold or sinus infection that will not seem to leave. My ears are constantly being poked at and I as well have no wax, damage, or clogging that is evident to the naked eye. To relieve some of the pressure, I bought ear drops at a local drug store, applied it to the ear that is worse, and experienced by far the worst burning pain for about 90 seconds and felt the drip all the way to my left eye and down to my throat. I figured I was either having an allergic reaction or I have some nasty infection to cause that much pain. I only applied the drops the one time but later that same evening, my ear started to drain fluid- and it was quite relieving! Although my left ear is still clogged and I am waiting to see if my dr can prescribe ear drops to flush out the fluid in hopes that will help both the pressure and my hearing.
