I'm brand new to this site and by sheer coincidence I encountered an issue with one of my ball pythons earlier today that I need help identifying. My albino champagne ringer shed yesterday, and today I noticed a few discolored scales on her back, down near her tail. They weren't there before the shed and I'm not sure if it has anything to do with the shed. When I run my fingers over those scales I can feel a slight unevenness as compared to her normal looking scales. She didn't have any real issues with her shed except a small patch just behind her head. Unlike the other two ball pythons I have, she likes to burrow through her substrate (cypress mulch) quite a bit. I'm wondering if these marks are due to her digging - did she just scratch herself, or is this more serious?

Any insight or help would be greatly appreciated.
