Esperanza,
Assuming your ENT had an MRI done (properly) to rule out an acoustic neuroma (if s/he didn't, GET IT DONE!), you can also try direct steroid injections into the middle ear. There are numerous articles and studies on the internet about it. I can't tolerate oral steroids, and asked my ENT about the injections through the ear drum. He put in a tube (just like little kids have when they have chronic ear infections, for example), and I only had to experience the discomfort one time. I had twice-weekly injections of about .5cc dexamethasone for 3 weeks. Unfortunately, with profound loss I knew my chances were slim for recovery, and I did not regain any useful hearing (still severe to profound loss, depending on the frequency range - and what does get through is severely distorted so no air conduction hearing aid would work). But at least I tried, and will never have to wonder, "What if...."
So if you can't tolerate systemic (oral) steroids, talk with your doctor about the IT steroid option. It may not be too late, particularly if you didn't end up at the profound loss level across all frequency ranges. Don't give up yet! And don't panic too badly. It's very scary at first, but you get used to it, and with the assistance of one of the several devices available for people with single-sided deafness, you can at least improve your inability to hear on the "bad" side. You won't regain directional capability if you've got severe or profound loss, but you'll also learn to live with that and often not even think about the fact that you can't hear out of the "bad" ear. I had nearly 58 years of normal (actually outstanding) hearing until I woke up totally deaf on one side a year and a half ago. It's life changing, but not nearly as devastating as it first seems. Now it's more of a minor to moderate irritant - and only at times. Most of the time it isn't much of an issue anymore.
Best wishes,
Chris
