Adrenaline. When your monke ancestors faced danger, they either had to fight or flee. If a predator ripped off their arm, it wouldn’t do them much good to worry about it at that moment. Adrenaline turned off the pain part of their brain so they could run fast enough to get away or, alternately, gave them the strength to beat the predator away with their own severed arm.
Several generations later, here you are with the same adaptations.
