Ah well, that didn't last long did it.
You're most likely over reacting after reading some nonsense from some where, never take medical advice from the internet, if you have a problem go to a doctor.
On a more helpful note, I damaged my nostril as a child, you can't tell from the outside but one nostril is not as open as the other hence I can blow more snot from one and nothing at all from the other.
It could also just be a cold.
