Doesn't it strike you that, if you can't hold a UK medical, you're, fundamentally, not 'fit to fly' in the UK?
You might be able to twist the rules and keep flying, but it'll be through a loophole which will, in due course, perhaps be closed.
Fierce irony if you were to have an accident with a some element of medical cause.
Why not accept that there's a medical 'problem', and accept that flying requires a high medical standard, which, sadly, you don't meet any more..?
I'm sorry to hear you can't have a UK medical - but it could be worse, no?
