Hi sandysage,
I have not experienced a clicking but have experienced an arythmic tone, like morse code in my AN affected ear which is always there but varies in volume. I have spoken to a neurootologist who specializes in tinnitus and he thought I had stapedial myoclonus, a type of middle ear myoclonus. Yours sounds like it could be a middle myoclonus as well but from the tympani syndrome. Weirdly, I did experience the clicking too but only for one or two nights when I couldn’t sleep and was very stressed. I heard it’s also called typewriter tinnitus. If it’s just the clicking sound, I wouldn’t say that symptom alone means that it’s an acoustic neuroma, as there are other causes for this. What are your other symptoms? It’s good you’re getting an MRI, and you’ll know for sure from that if you have one or not, given that you’re getting one with contrast. I hope it turns out that you don’t have one.
Best wishes,
CA Marti
