From the experiences of multiple relatives and in-laws of mine
.in Mexico.
While they are living in Mexico, all are US citizens living and working in Mexico,,,,,
Their ease and ability to quickly see a doctor on short notice is fantastic.
English speaking doctors,
Great immediate medical care, and testing, and their doctors visits are not rushed as in US,
Doctors give plenty of time to patient, not rushed through doctor visits as in US.
Test results are fast.
Medicine prescribed is extremely inexpensive.
One relative wanted to use their Medical Insurance they specifically bought
for when traveling in Mexico,,, CLINIC IN MEXICO said
(Never bothered to use that medical travel insurance, what for)
do not worry about you paying anything now, just wait after you finish here,
.their TOTAL cost was about 650 pesos ($32 USD),
..their prescription cost was only about $4 US
Thats including doctors visit, lab work, etc
One of my relatives stated that she received the best care In Mexican clinic she went to in Puerto Vallarta than in any of her Doctor visits in USA
