What is gangrene? What are its symptoms?

In brief: Depends

Gangrene is dead tissue.
It can be painless, as in dry gangrene of a toe in a person with diabetes or vascular disease. Or it can be very painful, if it is somewhere that has intact nerve endings. Medical attention is mandatory, because if untreated, it can--and frequently does--lead to death. Even treatment sometimes is futile if it arrives too late.
