I agree with JudyS, dealing with Spanish speakers over the phone is hard. My Spanish is good enough for chatting with someone on the street, but the minute you add unusual words like medical terminology, and remove my ability to use visual cues like pointing and demonstrating, things go downhill. I've been able to book appointments in person in Spanish, but doing so over the phone is a lot more difficult. And I love when you ask for "un poco más despacio" and you get "un poco más fuerte, pero muy rápido"
Thanks for the input everyone. My takeaway is that you can get a full physical, with hospital tests if needed, by requesting it through one of the docs at the local clinics, and it's not necessary to find a doctor based out of Hospital Chiriqui.
