ELI5: is there a limit to the amount of physical pain our brains can process?

Yes.  There is a point at which the nervous system is overloaded and just stops processing input.  That's pretty much why people who are self-immolating can just sit there in a completely calm state or even walk around like a normal person.  The only people completely on fire that run around screaming are the ones that actually don't want to die.
