Get a few good pics of her up so we can check it out. She could have scoliosis and you just never noticed it because its not bad enough and you were away all the time. I have a Frog that has Scoliosis and it looks like a lump, but the distortion of his lower spine is very apparent and easily seen. He's a year old so the scoliosis should not progress further. He eats well and does everything a Pacman frog does. He is also a big teddybear and will sit in your hand and not feel the need to leave it

I adopted him from Mike of Mike's Phat Frogs.
