There's a number of competing theories as to why this happens, possibly an evolved response to help control bleeding or vestigial tonic immobility (feigning death to hide from predators). [2] Either way, it's kinda fascinating.

In my third week or so on the ward — three weeks after graduating from medical school — we got a man who'd been in a fight whose arm had been sliced open by a broken bottle down to the bone, the injury being about a foot long. The thing was, he was so drunk, he wasn't in any pain yet was perfectly conscious.
Me and a fellow intern spent 3-4 hours in the early morning suturing him up after copiously irrigating the wound with many liters of sterile saline. We'd NEVER done anything remotely like this in med school, so we simply did what we'd learned from watching and reading. We must have put in hundred of sutures, starting with deep muscle and then moving outward layer by layer. We worked from opposite sides of the surgical field. During the entire procedure the guy never complained of pain, but rather talked with us perfectly rationally.
When we were done, we were certain he'd become septic and require weeks of IV antibiotics, but darned if that wasn't the case: he was discharged back to the County Jail after a couple days, with no apparent infection.
I'd say it's very annoying rather than kinda fascinating. Cannot donate blood. Routine bloodwork can become a chore. Minor doctor procedures become gripping.
Doctors/nurses don't like it either, apparently they do not want you to pass out during these transacations.
And since it's a brain-based thing, thinking about the issue, "ok, I'm not going to let this bother me" actually just enhances how much it bothers me. ugh.
I live off grid, and barely a day goes by that I don’t cut myself and have blood dribbling out, somewhere - and it doesn’t bother me in the slightest - even some pretty gruesome injuries (like bifurcating my thumb with an axe) are just “well, crap, that’s going to need stitches”. Even when it was stitched up, the needle going “click” as it pushed through the underside of the nail, I just watched with fascination.
That all said, every time I have a phial of blood taken, I faint, like clockwork. I’m not convinced that it’s the sight or thought of blood, but perhaps a marginal drop in BP or available blood glucose triggering syncope - but I’m not a doctor, just confused as to why it’s triggered by blood being drawn, but never by accidental bloodshed.
Anyway, thanks for giving the phenomenon a name.
Any idea what you call the feeling in your belly/spine when someone describes a nasty injury?
