What Could Yellow Waxy Scab In Nose After Allergic Reaction Indicate?

Hi there,

A few days ago I spent time at a friend's place where they had a cat. Occasionally, when I would touch the cat I would experience mild hayfever allergies, and sneezing. A couple of days later, I noticed a small yellow waxy scab forming just inside of the tip of my nose. There is no smell, but it does feel painful when removed or picked, with some very minimal bleeding. Whenever the scab is removed, it also quickly reforms like a plug over the area. I am thinking that maybe I have accidently cut it when itching my nose from my allergies. Is this a possibility? Thank you!
