Scott F and CTBarrister,
I live in Sweden and the way it works here is that if you want or need immediate attention you go to the emergency room where they can do all necessary tests and scans as it is taking place in a hospital. The local clinics are there for non-acute general medical issues.
At the emergency room they decide if you need hospitalization or if you can go home and wait and see. The doctor there, an intern and not even a fully licensed physician, didn't think I need to be hospitalized so she sent me packing. Of course I've been in touch with my specialists but the feeling I've gotten from them so far has been that it's probably a viral infection and that it should just go away on it's own... But I reached out to them today again so I'll see what they say as I suspect they too are starting to wonder what this "fever of unknown origin" is really all about.
Anyway, thanks guys. I'll keep you posted so check back in if you're interested in seeing how this whole thing plays out.
