Doctors surgery in Castillejar

Luckily haven't needed the doctor very often but I have recently been told that to visit them in Castillejar you need to have an appointment made by phone or internet. Unfortunately person who gave me the information did not know the phone number of web site. Can anyone confirm appointments are now needed and if so what the number and web site are? Wish they had stayed with the turn up and take a number system.
Thanks for any help.

I believe you do need to make a prior appointment. Here's the link for making an appointment online. The advantage is that you can choose your time. I don't know if it works the same way at the surgery in Los Olivos - must ask the neighbours!

Here's the freephone number to make an appointment by telephone too
Salud Responde 953018799

all in Spanish, but they're patient..
You need to ask for a 'Cita' then give them your 'ANXXXX' medical number, and tell them where you need to go. It's a pretty efficient service!

Quick update: the Wednesday surgery in Los Olivos doesn't use the appointment system - just pop in and chat to the neighbours while you wait, the old fashioned way!
