The other day I had a booger I couldn't blow out of my nose so I looked inside my nose with a magnify mirror and phone light. I found that the inside of my left nostril the cartilage is sticking out. Inside my right nostril it caves in matching the left sides bump. I got hit in the nose about 6 months ago by a dog but my nose was never broken did the dog do this or is it something medically i should worth about.
