Went into her cave and slept there for about 2-3 days, her cave is right under the basking lamp, but I thought she was brumating so I didn’t think much of it. Than she came out recently, and I looked at her and saw discoloration in her upper back and her tail, kind of a faint pink purple kind of color, I’m thinking it has something to do with shedding but I’ve never seen her shed her back or tail and haven’t found enough shedded skin to think she shed her back. She seems fine, she ate when she came out the cave than basked for a while than started walking around her tank. Should I be worried?
