Okay. I'll try to make a long story short. So a few years ago getting outta high school and getting a job promotion and all I started to decrease my animal collection pretty much. I work at a pet store so one of my friends there said she would take my Crested Gecko. As she was a year old and had everything and they are pretty easy to care for. So I let her have her and a month later she gave her to my boss, because she was 'bored' with her. I got her at the all Ohio reptile show back in 05 and she always had eating problems. She would NEVER eat baby food or the trex diet made stuff. So I would have to force feed the diet stuff weekly and she would eat crickets and bananas. So anyways eight months later my boss slips to me that she gave her to her sister and her kid plays too rough with her. Oh and she only gets crickets every other week. So yeah I threw a fit and wanted her back. Seems funny all like six animals I gave away I ended up back with, lol. But she didn't wanna give her back. Well two weeks later she was 'weak' and decided to give her to me. So when I got her it was at work and she was sooooo skinny. Her back bone by the tail was showing. She couldn't stick to anything at all. Her tail was floppy. Her toes were curled. She had skin patches from a recent bad shed. She wasn't the right color. And she has an over bite. And a huge lump on her chin. I literally cried. Blaming myself. So I take her home. Six minutes home and I get home and I could swear shes dead. Shes not moving. Hard. And just flips over. But I see her breathe and soaked her. Idk it is was all the stress or what, but to this day it's a miracle she's alive. So anyways it's been three months now. She's an excellent weight. She's loves that diet stuff now! And her tail is no longer floppy. And she sleeps hanging on the glass! So I realized some things can be perm, but will her jaw always be underbite? I never really had reptile problems so I don't know? Also what is the huge lump hanging off her chin? It's like a knot, like a tumor, and it just hangs, its pretty big too. Prob an inch. I've read and seen things were maybe it's a vitamin deficiency or something? Who knows what was going on. I just know she's doing great now and I'm happy to have her back. I thought about taking her to a vet, but we don't really have any good reptile ones here. And I'm scared they will say put her down or something. So, thanks for listening to my story. And any idea what it could be?
