On my cartilage inside my nose I have a tiny bit of white sharp bone sticking out. I think it is actually part of the cartilage bone that's been exposed after I cut myself while shaving nose hairs. But I'm not exactly sure how it got there. I've had a couple of years now. It's not painful but I can always feel it there and it's more annoying than anything.

Any ideas of what this could be / what it's called?
