ZacharyJames,,
Welcome,, so sorry for your health issues. Sounds like you have had a hard time getting someone to take them seriously,,, so sorry. That can be very discouraging! Not many doctors have experience with ANs and a diagnostic MRI without using the contrast agent, gandolinium, (Sp?),, would not be likely to show a small AN ,,
I just wanted to give you a suggestion of doctors in the area from my experience,, you say you are at U of AL,, I'm guessing at Tuscaloosa,,, there are knowledgeable doctors at UAB at the Kirklin Center who would probably be your closest. Dr Ben McGrew is an otolaryngologist with experience and he teams with Dr Winfield Fisher, a neurosurgeon, for surgery. This is the team I used and they are quite knowledgeable and qualified,, if you can get to Birmingham that would be a good place " locally" to start. ( I have not heard of any doctors in T-town).
Then you also have a good resource at Vanderbilt in Nashville for a second opinion once you are diagnosed,,,, they have wonderful doctors there and a wealth of knowledge,,,
I hope that helps and I hope you get some relief and answers soon,,,
If I can help further,, feel free to PM me,,good luck!
