clinton, if you got an artery then i think you'd see bright red blood.
if it went bad on you, i suspect that signs would show on your extremities (toes, in this case).
i think it's a miss ... i hope it's just a miss.

HR thought of the day: please try to avoid shooting Methadone into the feet/ankles; i have only done this once or twice and NEVER again. it's a cost-benefit thing ... i'm back to oral 'done and very keen to keep it that way. it's just not worth the risk !
you may need those feet veins for medical use later.
