Every person has a different pain barrier.
for me it is very low.
very very low.
think.. paper cut.
i have ALWAYS been like this, even as a baby.
Some Examples:
On a premilinary date with my last long term BF, we went to a really nice restaurant, ordered great food, great wine spent a fortune and the FIRST bite i took.. i bit the side of my mouth. i bet some people do this quite a bit. but not me, i felt like i needed morphine and once i tasted the blood, i passed out in my garlic prawn entree and Tim had to caryy me out to the car (where i came to) and take me to the hospital, where i was given drugs for "shock".
after working in my 1st job a few months i was filing. i cut my finger on a piece of paper enough to bleed. the room span, my finger felt like it was on fire and i tell you no lie, my brain goes crazy and makes me think i'm about to die. one of my fellow staff found me semi concious on the floor and drgged me to the tea room for a cold wash cloth. i had the rest of the day off. shamefull but true.
there are a thousand more just like this.
my BF however once while motorcycling cross country caught his arm on a tree branch, severed 2 tendons and needing 25 stitches got back on his motorbike and rode himself to a hospital (1.5hours away) without even caring. this guy once lost his knee cap on a superman motocross jump and didnt even notice till he was walking in the gate at home! ... pull the hairs under his thighs though and he'll scream like a girl so go fiure.
