Perhaps my bar is low, but I expect poor medical treatment in 3rd world countries. Glad everything turned out for the better.
First, I don't consider MX third world. Look up your definitions.
Second, I was recommended by DAN to a hospital in CZM for possible bends. I was seen by the admitting doctor, the emergency room supervisor, the emergency room intern, and the DCS doctor within four hours. I was given IV and oxygen during my visit. I considered it better treatment than I have received in the USA (first world, btw). If I were to be treated for DCS (again), Cozumel and DAN work for me.
