Whats wrong with my cats nose?

[mystraycatshelp]

At first I noticed the scar/crush on the side of her nose and I have 2 cats so I thought maybe it happened while they fight or she hit her nose. But today I noticed the dark spots on her nose. Google said it might be parasites or some kind and it scared me a lot because she also attacks her tail sometimes and once I found a very little black bug like thing. But didn't take her to vet when I couldn't find any again.

What's wrong with her nose?

I would get her to the vet for a diagnosis. It could be nothing, but it could be something like acne or allergy to something.
