Flagyl is garbage. Its cure rate for parasites is very low. Specialists who know what they're doing almost never use it by itself anymore, they combine it with other antibiotics.
If they didn't diagnose a parasite, then how do they even know what to use in order to treat it? Throwing random antibiotics into the body with the hope that you'll get better is not evidenced based medicine.
It's possible your body picked up some unfamiliar microbes in your travels. They may or may not be parasites. People all over the world have different gut flora based on where they live, what they eat, the water they drink, etc.
The modern medical O&P test for parasites is also garbage. You need to fork over some money to get proper testing with a comprehensive lab, like Genova, DoctorsData, or any that does PCR testing and comprehensive stool cultures.
