Hi, Miriam and welcome! Years of vertigo - severe episodes periodically and mild to moderate the remainder of the time, was one of my biggest concerns. With the size of my tumor, I did also have the choice of surgery or radiation for treatment. I agonized over it, as do most people, for quite some time. I met with numerous docs (both types of docs). As Phyl notes, most docs are "predisposed" to a certain type of treatment and I knew and accepted that. Ultimately, what I did was decide which treatment I could live with, so to speak (went w/ the gut feeling) and then chose my doctor. I chose surgery for various reasons, but one of the main ones was that I wanted the balance nerve completely cut so that there would no longer be a bad signal coming from that side. A little wooziness I can handle, the debilitating vertigo, was another matter. I have had no true vertigo since surgery...yes, still wonky at times, but no big deal...not to me, anyway. However, as you've already been told and will hear over and over again on the forum, everyone's experience is different.
Best to you as you go through your AN journey - we are here with you!
