Daydreamer -
I'm not a doctor, but IMO if you are having symptoms like the ones you describe, watch & wait might not be the best option for you. Also the fact that your AN is 1.7 cm makes me curious as to why you would watch & wait, since it is my understanding that this is about medium size.
I urge you to find a doctor or doctors you are comfortable with before making a treatment decision, don't let your insurance company bully you into anything. It is vital that you find someone with the qualifications, as well as the experience, to treat you.
I'm hopeful that you will have a good consultation tomorrow with the specialist at the Michigan Ear Institute. If that doesn't work out, I have an excellent doctor here in Illinois - not too close for you, but not too far either.
BTW, I had dizziness and balance issues for a few weeks post op but after that they went away, never to return.
Best of luck,
Jan
