[Marvel] How do Wolverine and X-23 not go into shock from the pain of their wounds?
gpt
It's a combination of a few factors.

First, they heal pretty damn quick, to the point that they often start the healing process before the wound is even fully inflicted. Presumably, this means they never feel the full pain of most of their injuries, and if they do, it isn't for very long.

Second, adrenaline is a thing -- even people without healing factors or superhuman durability have been seen powering through stab wounds, broken bones, and even dismemberments as if they aren't even there with enough adrenaline pumping through their veins.

Lastly, in the case of Wolverine and X-23 specifically, they have some slightly enhanced/altered mental functions as a result of their mutation, including their famous berserker rage, in which they are able to completely ignore pain and fatigue. While they rarely use it in full due to the danger it presents to their allies, a minor version of it seems to be near-comstantly active, at least in combat, as their general demeanors and fighting styles display.
