It could be a lot of things. The only way to know for sure would be to take it to your vet. Intranasal infections can cause bleeding; so can tumors and trauma.
Bleeding from inside the nose or ear is most commonly caused by an infection, which can erode away the tissue... i am really sorry to hear this :( it sounds really bad
