I can feel a bone protruding in the inside of my nose, it is relatively close to the nostril, and I'm not sure, but if I would have to guess I would say it's either part of the volmer or nasal concha. It doesn't hurt at all, and it protrudes as much as maybe half the height of a fingertip, if that. It feels rounded on the top, not sharp, so I wouldn't think it's a fracture. I have not taken any serious blows to the face, and the only thing I notice is a consistent stuffy nose, but that could be due to allergies I am not aware of. I'm really just curious as to what it is and why it's like that.
