Thanks for the input guys.
I might try the pillowcase trick. I attempted handling her again today and even after she un-balled, she kept her neck in an "s" position the whole time.. She did attempt to explore a tiny bit, which is a step in the right direction I guess.

Lady mkrj58 - If only I had a reptile vet around, I might try that, but there are no vets with any reptile experience here... I haven't seen any signs of worms (she pooped / peed normally just a couple days ago), but I will keep that in mind. If she doesn't start putting on weight or looses weight, I might take her in.
