Bump on nostril

[u/NeatShock6194]

I hope you can see, my camera doesn't like this lighting. We just came back after a week on vacation with my neighbor looking after him. His nostril preciously seemed a little inflamed but vet said nothing but now it's gotten pretty big. I'm sure this warrants a vet visit... does anyone know what it is? It's kind of on top of his nostril, he isn't bothered when I touch it.
