My female corn isle boa is currently in shed, so when I went to give her a light misting I noticed she looked rather swollen in her back half. When I took her out I was shocked to find her looking like this...

Just to cross out my first thoughts:
Shes not a fantastic eater so it's not obeseity.
She couldn't possibly have injested her newspaper (thats all thats in her tub)
She is not constipated
The lumps are soft and squishy, and they were NOT there a week ago. Does anyone have any insight as to what it may be and what has caused it? I was thinking sporadic fat deposits but how would they develop over only 7 days?
