Why cant i ever breath through my nose?

Well first of all, you probably are a weirdo since you are asking this on yahoo, but a simple answer to your question: you might be a Wendigo. Now, you are most likely wondering what that is. A Wendigo is a creature that has cannibalistic tendencies, however, don't worry, if you eat raw meat, your nose issues will soon disappear. Or you could just could just go to the doctor, your choice. HOPE THIS HELPS.
