Had to go to the medical clinic (centro de Saude) in Pallas de Rei (blisters) they told me without health insurance they are not able to see me as they have not got the facility to charge me ... they will charge insurance. Iam not sure if I understood it correctly, because they said they will send paperwork to Santiago . Anyway I was able to send them the email, got treatment for free. Very nice staff. It is essential to have health insurance.
