I am really sorry to hear about your situation. I know time has passed since this all started and that is not ideal but there are doctors that deal specifically with this sort of thing. If you have the ability to do so, it would be worth your while to check out the House Ear Clinic in Los Angeles or the Ear Medical Group in San Antonio, Texas where there is a great otolaryngologyst named Dr. Susan King. I had a similar situation to yours many years ago with something called “Cochlear Hydrops” that caused sudden hearing loss. I did the inner ear injections, steroids etc. I was also given a medication called methotrexate that was at one time a chemotherapy drug. This medication given in small doses performs like a steroid but without the downside of taking steroids. As a result you can take it longer. Because of the small doses you don’t get typical side effects that one would associate with chemotherapy. Through all of these efforts I was able to get back a lot of hearing in my affected ear. I was fortunate that most of my hearing loss was in lower tones which is helpful since bass is omnidirectional; it is hard to tell where it is coming from or on which side you have a deficiency.
I know your situation is probably different but I still think it would be worth your while to seek out a specialist for advice. There is a lot of work being done on inner ear issues these days and there are many more advances since I started having issues.
Best of luck to you.
