He did, and the doctor said it was likely Leishmaniasis, but she didn't really pursue it (maybe because it's not that easy to cure, even if she was aware of the treatment), and he thought she was wrong due to the lapse of time, so he let it go.

And once the diagnosis was finally made, there were still delays because the doctors said they had to know which strain it was before they would give him the only drug known to treat it, and they had to get approval from somewhere because it's still not approved by the FDA.

In general, however, I think you're right about getting local diseases/conditions treated where they know the most about them.
