using my European Health Insurance Card in Playa del ingles

Hi jackser unfortunately I think you will find there are no medical centres open on the island for treatment  there are a lot of medications back home that you can buy over the counter at the pharmacies here  think that's the route I would go

The medical centre in Arguineguin is open Monday to Friday, not sure of the opening times. I have used my E111 there this week. Make sure you have your passport and you’ll be asked for your address.
