What causes dark colored toe nail when nothing fell on it?

A doctor has provided 1 answer

Fungus can : Cause this, so can a melanoma.....You should have it examined, it could be blood as well. You can get blood from simply walking, the end of the shoe can hit against the edge of the toenail and cause a subungual hematoma.
