Thank you for the advice
I went a few minutes ago and took her out of the cage and saw that she was trying to shed off the spots where her skin was infected and the vet had had to lance. It came off easily and the scales beneath are soft and red looking where they had been swollen. I think if I hadn't helped her, the infection would have gotten much worse. I treated the spots that were hurt and then held her for a bit, which seemed to help, too.
I turned the heat rock off so the sensetive spots won't get burned.
Right now there are fuzzy rats in her cage; she actually cuddles them at night cause they are warm. When I handled her I took one and rubbed it around her mouth so the scent would be there and whet her appetite. They stay under her heat rock since it's up off the floor- to disperse the heat so it won't burn her- so I don't think they are really bothering her and that's the only place warm enough to keep them going.
If I have to freeze them, I know how to get her to eat from something I found on here earlier. Bella should make it, but I won't forgive myself for a long time if she doesn't.
