That might have been the sudden release of endorphins in your body. Your body releases endorphins when you’re feeling happy or also when certain damages like that happen, I think it helps neutralize the pain.
i broke my left arm guys...
so i was enjoying my 12 - 14 kilometers per hour ride on a scooter when i tripped and fell down on my knees and arms, my right knee got a bit in blood but i decided to put a leaf on it bc why not?
then i came back home and thought this was over until... i became a accurate hitbo- nah but actually
i got hit by a sudden wave of pain then i found out that i kinda " snapped" my bone out of place; nothing; bored
