I am a Norwegian citizen. My work is in Norway, but very near the Swedish border. So, I could live in Sweden, and commute across the border every day to work in Norway. I would, of course, register as officially living in Sweden.
In such a situation, which public health care system can/must I use? The Swedish one, or the Norwegian one? Or both?
I'm talking about anything from a minor doctor's visit to serious treatment. And of course, only the public, (mostly) free health care.
