Texas definition seems a bit more objective.
PC Ch 1, Sect 1.07, Para (46): 46) "Serious bodily injury" means bodily injury that creates a substantial risk of death or that causes death, serious permanent disfigurement, or protracted loss or impairment of the function of any bodily member or organ.
I'm with NyleRN. Pain seems a wildly imprecise "measure". My wife can bump into a door from walking through the doorway and be in agony. After cutting and stacking brush I'll find scratches, small lacerations, a couple splinters, and not have been aware of them before I saw them. People roll pain and suffering into a single thing, but I think of it as "pain" = the physical sensation, "suffering" as the emotional reaction to it. Getting slapped by a stranger hurts and pisses you off, but getting slapped by a spouse will engage a whole new level of "suffering."
