Considering what he's had to go through to get the only med that is known to work, what would he have been treated with in S.A.?
Just because they know what it is doesn't necessarily mean they have the means to treat it.
But I do understand what you're saying about his not wanted to be treated outside the U.S. A friend's father came back here (from Switzerland!) to have surgery on his knee. They 'forgot' to give him antibiotics for a week, and he nearly lost his leg. Sometimes faith is misplaced.
