Many of the physicians in Nicaragua have medical degrees from schools in the United States, Mexico, Europe or Cuba and most of those in the major cities will speak English. Outside of the major cities and at public facilities, however, doctors and their staff may not be as likely to speak English.
An office visit to a general practitioner will generally cost about US$20, and only cash will be accepted. It’s not unusual for patients to have the cell phone or home numbers of their physicians and for the latter to make themselves available for consultation at just about any time.
The U.S. embassy maintains a list of recommended physicians who speak English around the country with their contact information.
