In general, when a limb dies, how long does it take before it falls off? Can you go years with a black and useless limb, or does it just.. fall off right away?

  • $\begingroup$ As it is the question cannot be answered, many variables play a role, such as where in the limb the necrosis started, what is the cause, health condition, age, etc. etc.. $\endgroup$ – have fun Sep 1 '17 at 14:09
