I experienced sshl in Oct 2014. My primary treated it as an ear infection and never sent me to the ENT until 3 weeks had passed.
The ENT explained (as you were told) that most likely the intratympanic injections would not help, but let’s try it, so I did. I did have improvement but it only lasted 8 or 9 days and then was gone. He repeated the injections, no change that time. So he sent me to his audiologist for a hearing aid.
I ended up at CostCo (pricing was a big factor), I only got an aid for the one ear, which at that time had moderate / severe hearing loss. My health insurance at that time would (and did) reimburse me up to a set $ amount, and by going to CostCo I had the one entirely covered. It helped a lot in my hearing and in my mental frame of mind. So I say go get fitted and get one. Esp. at CostCo, you get fitted, return in a couple of weeks for adjustments, so if your hearing is also settling in, that will work in to the fitting schedule. Plus, at least at my CostCo, it is a 4 week wait to get in. So you have plenty of time for things to calm down.
Fast forward to last month . . . during that time, the aid broke and was repaired twice. Also during that time, slow decline in hearing in both ears; which I had been warned to expect, by the ENT. About 2 weeks ago, I suddenly felt really tired about 1:30 pm, went to bed, slept half an hour, woke up to a whole new world of major hearing loss. This time I did not have that ‘fullness’ feeling that I had way back when. I didn’t bother with the ENT, just went to an audiologist. Yes, audiogram confirmed left ear is profound and right ear is severe. LOVED the demo pair of aids, just for purposes of confirming that getting aids WILL make a difference. But I have no insurance coverage for aids, so now waiting to get in at CostCo to get some.
Also, be aware, sshl is often an autoimmune issue . . . the immune system attacks the nerve which controls hearing. So you may have / develop other autimmune diseases as well. I already had Hashimoto’s (hypothyroid) and vitiligo - that one typically goes hand in hand with sshl.
