That's interesting. Some of my family in the US have done similar medical tourism in Slovakia.
With other friends' mother doctors would keep ordering injections, each worth 20,000 Rs ($300) confident in the fact US based son can surely afford it. In the end he ended up spending about $35-40K for about 2 weeks of treatment which ended with mother's death.
Medical council is in cahoots with doctors and hospitals. If anyone has grievance they can spend years in courts before they see any justice about medical malpractice.
