Unfit-to-Fly?

I got a call from my health centre today - and I was rather surprised to be told that the doctor wanted to see me next week regarding my fit-to-fly letter; I expected to be just given one - after all, Meniere's can make me really sick, and it does almost completely incapacitate me when I'm having an attack, but it's not as though my life would be in danger if I flew. It just might not be a pleasant experience.

I was advised by the doctor's proxy to talk to my airline and my travel insurance company about my condition, but clearly I will not be in a position to buy insurance until I have a doctor's letter in my possession.

It seems that my doctor may be worried about my fitness to fly, presumably after consulting with colleagues, and perhaps she wants to see me again to make sure I no longer look like the nervous wreck I did the day after my latest full attack last week. All in all, it's a rather curious state of affairs though, and not what I expected at all.
