Hi JeanneR .....
Have to concur with the previous responders to your post ..... get additional opinions.
Many times a very small AN can cause many symptoms that seriously alter ones quality of life. If you do not have a copy of the CD from your MRI, get one or more and send it, along with your most recent audiogram to other places.
There are many places around the country with experienced physicians in the treatment of ANs who will do free consultations if you send them your MRI and audiogram (if you have one). House Ear Clinic, USC in Los Angeles, Stanford University, University of Pittsburgh Medical Center, etc.
Unpleasant symptoms should be the driving force behind whether to watch and wait or treat. Sometimes you, as a patient, have to be aggressive in asking questions and being honest about how your symptoms are making an impact on your life.
At least with multiple opinions, you have a better look at your options and why. I know, for one, Dr. Friedman at USC will personally call you with 24 hours of receiving your materials to discuss his opinion.
Best wishes and let us know how it goes.
