In hcm, you will hardly see a private clinic. But there are lots and lots of pharmacies. And a few hospitals. That means medical is so bad that people treat themselves with drugs from pharmacies. Only when they get injured or very serious cases then they go to hospitals. My hotel owner got cancer. Unable to afford treatment, she grew codyceps in her kitchen fridge and somehow, nursed herself back to health. So how good you think the medical in vietnam is?
Saving money is one thing, but never do invasive procedures there. I saw stories of ang mo who did root canel there and things got out of hand.
