Hi Arnie,
I wish you well, and I'm very sorry you have the single-sided hearing loss and tinnitus.
No one can answer if you have an Acoustic Neuroma or not, without an MRI. I'm glad it's on your schedule.
I can certainly relate to the high anxiety before getting an MRI, in the period of time when one doesn't know what is wrong. One would like to know, but it is the MRI that is the tool for diagnosis. Speculation is pretty unreliable, alas. Almost useless.
I was told that I more likely had viral inner damage, to account for my single-sided sudden hearing loss and tinnitus. And that the odds of having an acoustic neuroma were very very low. But only the MRI knows, alas.
I have an acoustic neuroma, which the MRI found. It's small.
It's not what I wanted to learn, but it's also not the worst of the things I feared it could be. It will get treated, and I will go on, not exactly the same as before, but OK enough.
As for anxiety, I could probably write a book on how not to handle anxiety, as I tend to panic easily, but ... eventually I go back to the basic ways to handle anxiety: time in nature; time with friends or talking with them; music; meditation; exercise; a positive attitude; faith.
If I was giving advice to myself, pre-MRI and pre-diagnosis, I would say, get a few facts about acoustic neuromas, and then focus on your generally good health and wellness, physically, emotionally and spiritually. Do not dwell entirely in the fear.
I'm sorry it's so difficult not to know. It was for me, too.
All good wishes,
Skier
