Do not underestimate the language barrier between you and your doctor, a study done in 2010 by the The Institute of Public Policy Research (IPPR) followed up an earlier Brits Abroad report. 

That report showed that Study group interviewees who lacked language fluency compounded their medical problems. The risk of misdiagnosis increased. Patients could have difficulty making known what they wanted. Particularly in Spain and Portugal, charities and non-governmental organisations reported “significantly growing numbers” of Britons seeking repatriation because of failing health.

Don't t let this happen to you.
