I think this can be one of several subvariants. A version of the drug habit/self abuse trope that used to be demonstrated with late nights alone with booze bottles in some depressing living room. A blazing modern signal that the protagonist is hurt but continues anyway, to distinguish him from some impervious Superman or unfeeling Terminator clone. The writers are mildly concerned about the plot discontinuity and rushing him to the next scene. See also the bullet wound self-care with improvised extraction and bandage from ripped clothing, which leads to miraculous physical rebound. No debilitating blood loss, nerve damage, or torn connective tissue in this plot!
