Hello Brad,
Sorry to hear (pun intended) about your possible AN. There is a lot of good information on this forum, just keep looking. When you get overwhelmed, stop, rest a while and come back later. There is a section at the top of the page, from ANA with a forum for helpful tips. There is also lots of info in the AN Issues with a list of those who are willing to talk to you on the phone. There are users on the forum from all over North America, with the majority of course from the US.
There is also a list of questions to take with you to the Doctors offices. We all recommend taking paper and pen with you to write down your questions and answers. I also took another person with me most of the time.
In regard to losing your hearing, unfortunately more often than not, we lose our hearing on the AN side. There are quite a few on here that have retained their hearing, however I believe their AN were smaller than yours is. I wish you all the best in this journey. Come back often.
Nikki
