Our expert says:
There is no other condition that can be mistaken for gangrene.
The cause of gangrene to your hand can be due to a previous infection that has not healed or due to vascular disease that is causing the tissue of the hand to die and to develop gangrene. Consult your doctor as soon as possible.
