Finland has pretty cheap healthcare, but unfortunately it also means it can be pretty crappy sometimes (this varies a lot from place to place and from day to day). I'm really glad I have a dental plan from work and can use a private dental clinic of my choice, instead of a public one. But if the choice is between almost free and no healthcare at all, the almost free one is great of course. And getting a CT scan for 30 euros is much nicer than paying for the full cost (of course we pay it eventually in the form of taxes).
Best of luck to you Jo, hopefully they can figure things out and it gets easier for you.
