Nasal Effects Question, Help Needed

[Sorrysoul123]

Let's just say that someone used to snort a lot of adderall IR, but stopped about 3 months ago. Recently, this person notices that there is a crater-looking thing inside their nose on the septum wall. It is pretty deep and a bit painful, the edges are raised but it isn't a pimple or cold sore or anything, it dips in.

Is it likely that the snorting was what made this happen? The person's nasal care isn't exactly spectacular. And if it is from snorting, will it keep getting bigger? Is there any way to make it heal up back to normal?

This person is a junior in high school and is seen by most as one of those super good kids who never does anything wrong, so if a doctor sees the nose problem, the person would have a lot of explaining to do. The person realizes how stupid it was to snort adderall, and they have promised themself that they will never do it again, and have been successful thus far, minus this nasal issue.

This person thanks any responders for their help.
