Hugs to everyone who needs them! Exile, I have to recommend the rest in those circumstances! I hope it's going ok.
I had a slightly puzzling phone consultation with my GP. She's said she can't sign a document for me to travel for work because she can't ascertain that the country concerned will "have the necessary specialists for you to see them whenever you need to." With all due respect, even here, I can't do that and all bar one consultant has discharged me with a diagnosis and medication as the only follow-up (and the outstanding one will in June). She also told me I would be removed from all NHS systems after 3 months if abroad (although I would continue to be a resident here). I certainly don't want to travel if not fit, but I do feel it's manageable and, if she remains of that opinion, that means I won't be able to travel long-term
Have the rules changed on qualifying for NHS treatment, whilst living abroad? I lived in Spain for 11 years, but I remained registered with my UK doctor and I had no problem getting appointments, prescriptions, etc. I would have stayed with the same dentist as well, but she retired a couple of years after I left, so I had to find another one.
Admittedly, it's 11 years in July since I returned to the UK to live, so it's possible that the rules have changed in that time, especially given the current pressures on the NHS.
