I wuld float her in the tank to keep a good temperature. Upper lip is gone? could she have gotten into a scat with another female? I've got a male whose side of his face plate...part is missing. Bent spine can be from three things usually... internal problems, external (fight, something landing on her, she jumped out, got stuck beneath something...), and genetic.
For the upper lip problem, could you post a picture? if you can. Is there signs of different coloration in that area? any cotton like fluff?
