Hearing loss was part of a flair I had once. it came back once the flair was over.
I would tell your MD that you have spoken to several other patients that exeperience the same things, and hope that he doesnt give you the "stop looking at message boards, they will scare you to death" lecture.
If you feel he is being dimissive or treating you like you are just an anxious patient, it may be time to either have a talk with him, or move on.
