I have lived in Bangkok for a while, about 6 months a year for more than 10 years, and now I have left, for several reasons.
However, when I was there, my health at the beginning seemed to improve (no more pain, feeling better overall) but in fact did not improve at all. Blood tests were more and more catastrophic. Until they asked for the same tests you hve been undergoing.
Nobody there seemed to understand what was going on. In Europe I did not get help either.
This is because my lifestyle had been quite unique. Nowhere did they see patients who had my history.
Do not believe for one minute that high-end massage places are OK. I was going to the most expensive places. And to the most expensive medical facilities.
The truth is : your health is in your own hands.
In Bangkok you are being drugged in many ways. Not only the essential oils to relax you (they all are concentrated in the liver, that only does what it can - one drop of the essential oils that you think will relax you will kill a cat), but also the other drugs there that make it the capital of pleasure that it is.
All Asiatic towns used to preserve food with boric acid. Not expensive, kills most of the yeasts of a tropical climate, AND gives a testosterone high : prostitution towns, where males feel better and are ready to service armies of prostitutes because they can. They think it is because the women make them feel netter, maybe it is part of it, but the FOOD makes them feel better, the boric acid part.
Because there are now economic interests that want to sell Western preservatives and chemicals, boric acid is being forbidden more and more. Some politicians make money on the import of lets say PAA (Paracetic Acid) and other stuff.
The boric acid induced testosterone high is getting slowly phased out and the body does not have this artificial defense anymore.
Apart from that there is omnipresent use of more and more phomchurut (Ajinomoto-MSG). This destroys the HPA axis. You will notice that the olderThai people are nowhere to be seen. This is because they are dead. There used to be a nice supply of young healthy Isan people to come up for work. Now they too have had access to the dreaded stimulant in their youth and are not fit to work after a few years. Air rage is what you get when you eat airplane flood (forbidden to the pilots who get another type of tray!). Air rage is what is happening more and more in Thailand.
The truth is : there is another side to that Land of Smiles.
I was hooked. Now I know, I am not anymore.
And I am very happy somewhere else, in the luxury of a simple and real life.
Good luck and best wishes,
