I understand that although French Polynesia became a full overseas collectivity of France in 2004, it is not a Department per se. Nevertheless its citizens are French, with representatives in the National Assembly and able to vote in French presidential elections.

From everything you have said, your level of medical care for CRPS/RSD is markedly below what a resident of a major French city would expect and receive.

Accordingly, have you considered consulting with an attorney to see if it is lawful and/or constitutional to provide two levels of health care to French citizens, depending on where they are situated?
