Someone is due to fly to USA v soon but has a condition which flares up and for which the consultant appointment is not until after the holiday. So it is not yet diagnosed. It seems very hard to get insurance for this - easier if it were a really bad diagnosis than to have nothing. Friend really does not want to have to cancel trip when at the moment is healthy and able to travel (and so couldn't get doc note to cancel and claim insurance even if wanted to do that).
Any ideas or experiences at all? The person is pretty desperate.....
