Which hospital?

If you thought you may be suffering a stroke, which hospital Lakeside would you go to?

PUERTA DE HIERRO SUR or San Javier if you have the time/ambulance.

The closest one.
Preferred would be to call your own Doctor's cell phone and ask them. Based on symptoms, they may meet you at a local hospital or have been known to drive you personally into Guadalajara or organize an ambulance.
Timing CAN be critical but it is important to know whether it's a bleed or a clot that's causing the stroke since clot busting medicine must be administered fairly quickly.
Best of luck!
