I do not know if you seen Michel Moors movie “Sicko” but it is about how expensive the health care is in the USA. Maybe nothing much you can do about that as a private person except getting a good insurance or two maybe.
One thing you can do is shop some medicine that you need and know that the doctor will subscribe for you when you out traveling.
Like the movie showed us the Asthma medicine only cost a fraction in Cuba then price in a USA pharmacy and you not have to go to Cuba to get that cheap medicine.
Many countries like UK, Canada, China, India and Thailand have cheap medicine that the public can buy.
So next time you take a holiday be sure to make some profit from it, just make sure you check with the custom so the drug is not banned in the USA to import.
