My Largest female ball python Asus, has an odd spot on her nose.

Ive never seen this before, and im not sure it has to do with rubbing,or not... but hopefully a few opinions will point me in the right direction on how to handle this. If i should just wait until the next shed, or Bring her in to a vet now to see what could be going on.

I think its possibly build up underneath the scales...( Pus?Abcess?) but its possible its just swelling from the irritation and im just jumping to conclusions. Has anyone seen this before? its fairly concentrated to that one area of her nose, and the rest of her looks FINE! good weight, Great appetite * never misses a meal EVER* Looked in her mouth, and things look good there too. Shes a great snake, just.... not sure what this mark is from, and i dont want it to be something more serious.

She was moved to a new tub, from a longer one. Because i got new racks. and her temps are what they have always been at * no real changes other than size of her enclosure, which, if this is a nose rub, would explain everything, and ill probably just move her back.
