The bottom part of my nail bled because i cut my nail that had nail fungus too much. is it possible for the fungus to spread from the wound to my blood?

While it's possible for toenail fungus to spread to other toenails, between toenails or even to the groin, it would be very rare for it to spread through the blood stream to other parts of the body if you have a competent immune system.

The wound likely does not have any fungus on it since the nail fungus does not spread from the nail into the skin beneath it. Since there is no fungus in the wound, it cannot spread to the bloodstream. Good luck to you!
