Medical certificate for Belgian work permit, in Madrid

I need the medical certificate for Belgian work permit. I am currently staying in Madrid, Spain and looking for the list of certified doctors / health center, who may issue the medical certificate.

Is there any website / Link from where I can get this list.

Ask the belgium Embassy in Spain...
