The problem with retiring to Thailand is indeed health insurance. I lived in Thailand for thirteen years before relocating to France last year. The unavailability of insurance in Thailand was one of the deciding factors. If you can get a policy it would exclude pre-existing conditions, but you are likely to have a hard time finding coverage. When I looked at the problem early in my retirement the foreign insurance companies would typically not write new policies for anyone over 60. BUPA would take you if you were less than sixty years old with a promise not to drop you in the future, but that was an empty promise since they the rates were going to climb precipitously. The problem for the carriers is that the pool of older insurees is not so large, since the Thais are covered by the 30 baht scheme. If you can get a policy most insurers will drop you for age at some point, at 80 years old for instance, just when you need it most. As you know, the costs for Thai health care are relatively low, but not negligible.
The quality of health care that we received in Bangkok was very good, but I can't speak to conditions in Buriram.
In any case my information is not up-to-date, so you should keep looking. Maybe there are more options now.
Beyond that, I would recommend learning the language, which is possible even at age 67 if motivated. Don't know what the opportunities for Thai study would be in the rural areas like Buriram.
