There is stubbing your toe pain. Watching kids, this does not stop repeat behavior.
Then there is pain that is all you can do to not jump off a cliff to end it. This, tends to change personal behavior.
Then there is pain that is slightly less then jump off a cliff. But it goes on for months, non stop, making every moment a horrible experience.
This has a huge impact on all those around you. Some pity you, some try and help, some wish you would die already. Most avoid you.
Degree makes a massive difference. Wish it was otherwise.
Perhaps it made them more empathetic? When I visited the Museum of Human Evolution in Burgos, Spain, they took us out to the Atapuerca excavation site and told us they’d found evidence of a Neanderthal with a life-threatening tooth abscess. Apparently he would have been in incredible pain and his tribe(?) mates managed to keep him alive by pre-chewing his food for him. They also found evidence of disabled Neanderthals who were helped/kept alive by the group but I can’t recall the specifics of the disability to remember whether any pain may have been involved.
I would think pro-social behaviors like that have a serious evolutionary advantage.
> Because feeling physical pain is vital for survival, CIP is an extremely dangerous condition.[1] It is common for people with the condition to die in childhood due to injuries or illnesses going unnoticed.
