I feel your pain, literally.
A few years back, Xena's Guy had to tote me to the nearest ER for a kidney stone, and I waited four hours to be seen, behind kids with sniffles (whose entire families, incidentally, were there with them).
I finally told the receptionist that if they didn't give me something for pain, I was gonna throw up all over her and start screaming.
That worked, I'm ashamed to say.
Your threat was mild compared to the one I made a decade ago during my first stone: I told the doctor there were two available choices: 1) he could order immediate pain relief, or 2) I'd go to the drug room and take it myself.
Mine worked too. :-)
