Wow, all I can say is to make sure your neuro's all know your stories.
I too have had the and "pop" out and "fade back in" hearing in both ears and I totally don't believe there was an air bubble! Or the "fade out" and suddenly "come back" hearing. Tinnitus has always been a problem for me. As a child I had tubes in and out so many times that I lost count!
I will see if I can't get a hold of the article my neuro is referring too.
Frank, I do believe your problem with hearing is associated with that long list of music!!!
