Holy christ that's so terrible it crosses back into hilarious.
At a guess, the guy probably wasn't insured, so was trying to avoid seeing a doctor, let alone an ER trip.
My worst (that I can recall) was oral surgery when I was 8 or 9. I apparently had extra teeth in my front gumline (10 years later I had seven wisdom teeth pulled), so they wanted to remove the extras. They did it by pulling my top-right incisor and pulling the teeth through the newly-made hole, but the doc used a local anesthetic (read: short-lasting) because it'd cause less bleeding.
So about 10 minutes into the recovery room, I'm bawling my eyes out - and I was a kid who, when I broke either arm (right at 5, left at 8, both from falls while climbing) cried for maybe a minute afterward. But this one had me bawling until we managed to get the prescription filled (they had none on-hand).
And I had the in-grown operation too, but that's because I was a dumbshit and tore my nails rather than clipping. Got a colonoscopy scheduled in a few weeks, but I'm a bit ambivalent as to how necessary it is at 28.
