I've got a hospital appointment next week about something that I think might be serious, but I don't have a diagnosis, I think they will need to do more tests, maybe an MRI. I have several holidays booked over the next few months - if I take out travel insurance now, can I say I don't have anything wrong with me (not sure exactly what the questions are)? No point doing it if they won't pay up, in the event I can't do some trips or have to change plans.
