Thanks for all the responses.
I had actually done fairly well at putting all this behind me and moving on with my life. I knew that my hearing was not improving and possibly deteriorating on the left side. However, I felt that even if I lost it all on that one side, it still wouldn't be the end of the world. So, I was in that happy place again.
But then tonight, when I was on the phone, I decided to check out the bad ear (the left), something I hadn't done in weeks. To my dismay, it was much worse. Basically no comprehension at all in that ear. The voice on the other end sounded very faint and garbled.
Worse yet, I'm now pretty sure my other ear is affected too. I've been noticing some high pinging tinnitus sounds in the right ear over the last couple of weeks. I'd been doing my best to ignore it, but since the left ear was so bad tonight, I checked out the right one and noticed a significant drop in the high frequencies.
I'm going to both call my ENT back and ask my PCP to refer me to an oto-neurologist. But at this point I feel like I am going through the motions. I don't have an acoustic neuroma, so no matter what I have (I'm thinking possible autoimmune inner ear disease now), it seems like corticosteroids are the treatment of choice. And I'm just not going there again, especially not long-term or high dose.
I'll probably just go deaf in a year or two and will have to accept things for what they are.
