We had something very similar, years ago. Severe stomach pain in my 7 year old. We also went to the emergency room, thinking perhaps it was appendicitis.

The doctors called it constipation. Gave an enema, if I remember correctly. I'm not sure if that fixed it, or it was just "to do something". It probably would have gotten better by itself.

A friend of mine recently got bitten by a scorpion in the US, while sleeping outside (not in a tent because it was too hot).

He was unfamiliar with scorpion bites, and how serious they were. So, he went to the hospital emergency room, but stayed in the lobby. I believe he had a super high deductible emergency health insurance.

After a couple hours, the staff told him to leave, said if he hadn't had a serious reaction by now, nothing was going to happen, and nothing did. So, that's an option as well.

BTW - I've switched to the Crowd Health Black Swan plan. Crowd Health is a health-sharing plan (not health insurance, which allows them to avoid all the regulations), and the Black Swan plan is a very high deductible version of it. I haven't had any "health events" yet, but I definitely like the idea of it.
