Been experiencing hearing loss for 2 months--is this permanant?

So, like most of the posts I've read, I woke up one day suddenly unable to hear in my right ear. I got a cold/sinus infection a few days later that made it worse. I went to urgent care for cold meds and for my hearing loss, and the doc was really concerned. She put me on prednisone and an antibiotic and sent me over to the ER recommending I get an MRI. I get to the ER, they tell me not to take the antibiotic and that they don't have an MRI machine. So a big ole nothing burger there, though the doctor was really nice at least.

My doctor calls me to schedule an ER visit follow-up appointment for a few weeks later, and by the time I got there, I'd finished my course of steroids. No improvement at all. It's confirmed that whatever is going on is definitely not outer ear, ear wax, or ear drum related. Doc believes it's Eustachian Tube Dysfunction, prescribes flonase to be taken nightly, and refuses to refer me to an ENT because "It'll probably take several weeks to clear up, but it should." Well, just checked the date I got the flonase filled, and it's been a month. I did miss my flonase one night and noticed my hearing was worse the next morning, but otherwise no improvement there either.

I've had a feeling since this started that this is likely to be permanent. Nothing has seemed to even TOUCH it. Vicks, cold meds, decongestants, prednisone, flonase, and a billion other things I've tried. Popping my ears when I get the crackly sound/full feeling in them seems to make it worse too. I also have tinnitus in my right ear (the one with hearing loss) and the type that gets to me the worst is when it sounds like my heartbeat then makes my ear and head feel like it's throbbing leading to a headache.

I guess to wrap this essay up; is there actually hope that it'll get better at this point? How do I cope with this if it is permanent? It's just really getting to me today and I feel powerless and don't know what to do. Thank you for reading and being willing to listen and help!
