My 17 yos has had a sore throat and mild fever for a few days, and was complaining of a white patch in his nose for a few days. I finally got out a flashlight and looked at his septum, and there is a scaly-looking, round white patch there, with a raw crack in the middle from when he wiped his nose and stretched out the skin too much apparently. The sore is very painful - he says it stings when his nose is even touched on the outside. I thought maybe it was leukoplakia, but everything I've read on that is mouth-oriented.
Anyone know what this is, or what I should do? Thanks!
