Mickey,
I live in Denver and go up to the mountains a lot (probably 20 times or more each year). It is not unusual for people going up in altitude to have problems with their ears popping, etc. I have never had a problem at all with my ears until this past winter. Two times as we were driving up to go snowshoeing, my AN ear started clogging up, and I could barely hear. When we came down from the mountains I didn't feel any change for about 45 minutes. It freaked me out, and it gave me an idea of what it might be like to have major hearing loss in the AN ear. Like I said, I have never had this happen before, and it seemed odd that it would happen now after living here for 16 years. This past year I had slight growth of AN and some hearing loss. I might just be looking for something that in reality is not related to the AN. I think I have become hyperalert to just about everything related to balance, hearing, etc. since I found out that my AN has grown. Weird.
