There's an old saying in Patagonia which says that the best doctor in the region is Aerolíneas Argentinas - i.e., as soon as you feel seriously ill, you jump into a plane to Buenos Aires. I can see that is still the case.

Anyhow, I'm glad you sorted your emergency out and that there were some medical facilities in Chaltén. Towns less than 10,000 people can be very tricky here medical-wise, especially when they are so far away from big cities.
