This wasn't my patient, but I giggled about it for about an hour.
During a time of extremely high volume recently one of my colleagues was triaging an irritated and impatient young woman with an minimal (not urgent) complaints. Her list of chronic illnesses (fibro, back pain, anxiety, migraines, etc.) was reviewed, as well as numerous meds and seemingly dozens of allergies. She added to the list:
"...and I also have pain___", mutters something unintelligible .
"Excuse me, I din't quite catch that, could you repeat it?"
Looks more annoyed. Says a bit louder, "PAIN___"
"I'm sorry, I'm just not getting that"
Now pissed. "Paintol! Paintol!! "I HAVE PAINTOL!! Are you deaf?"
Apparently has a tolerance for pain and has made it into some kind of syndrome.
It is not a thing.
