I was diagnosed before Christmas and am in the wait and watch mode since the AN is small 4mm x 5mm. I also do not have any hearing loss so they say. I presented with severe vertigo which lasted for over a month. ENT sent me to get a MRI just in case (don't really know if he was looking for an AN or something else). Anyway the specialist said the vertigo probably wasn't from the AN (perhaps a migraine symptom without the headache)--still confused about this. Since the first week of Jan. I haven't had any symptoms, I guess. I'll catch myself being a bit dizzy, off balance with a slight high pitched noise in the ear, but it's nothing to get all excited about. I figure I might just be looking for something that is not really there. I do have a hard time with background noise and hearing words correctly, but the hearing test said I am ok. What I am looking for here is feedback from you about having what seems to be no real symptoms after being diagnosed. Or does it just come and go? Will I have another bout of vertigo only to hear the doctor say it is not a sign of the AN. It's like is it really there, even though I saw it on the MRI. I just don't know what to expect. Is my mind playing tricks on me? Thanks ahead of time for any thoughts you might have.
