Thats good advice. Also, just because the thai allopathic physicians you saw dont know (classically trained physicians everywhere generally suck with problems like this) doesnt mean another thai doc, or “naturopathic” type physician wont be able to help. That might still be a good idea. Especially if you could find one more local to you than thailand. Other diagnostic tools such as live blood analysis might help too. If all else fails, several people have actually found success with things like the bob beck protocol.
Basically, though, dont stop searching for the right doc.
