Just a a precaution, I have changed her bedding to paper towels now. And in case of the start of a thermal burn, I've moved her U.T.H. to the side of the tank. It's still spitting out about 90 degrees on the hot side. I also put some antibiotic ointment on whatever it is. She appears to be doing fine. I'll throw normal substrate back in, in a few more sheds and see if she gets rid of this crease.
