True Life: I went to the ER in Mexico

I was recently working and living in Cuernavaca, Mexico, and got pretty sick… We are (romantically) talking about days of not leaving the toilet, not sleeping, not eating. Unsure if it was food poisoning or an infection, I called my travel insurance company, and they instructed me to head to the ER. I began to Google, ‘how much does it cost to go the ER in Mexico?... ‘what is going to the ER in Mexico as an American like?’ and couldn’t find any straight answers. Per usual, I guess I was finding out IRL.
