I have similar issues. The tinnitus was a pleasant whooshing sound in time to my heart beat initially and I still had excellent hearing. Then a few months later I suffered SSHL & went severely deaf in that ear and the tinnitus changed to an unpleasant, non-pulsating buzzing static sound that is constant but varies in loudness. My rt ear is now hypersensitive. Everything is louder and startling. My husband is emptying the dishwasher and I just want to scream. I hate being in the kitchen with him at same time when we prepare meals. Restaurants are horrible or even visiting with 3 people in a home takes real effort and is tiring. Sound localization is frightening to me. Once I thought we were having a freak summer rain storm because I heard it pouring outside, so put on my raincoat to take the dog out. Figured out it was the dishwasher running. The fullness in my ears, feeling like I'm underwater or in a barrel fluxuates and sometimes when I talk the sound reverberates or buzzes in my deaf ear so that I don't want to talk. But fortunately that doesn't happen all the time. If I raise my voice for any reason it always does but often even when my voice is low. It's such a difficult experience because everyone's symptoms are a little different and they change hour to hour. I'm trying to meet the challenge but my world has become very small & I seldom leave the house. I'd like to get the cochlear implant that my Dr recommends but Medicare will only cover an Osia bone anchored device since I have good hearing in my right ear.
