Broken ribs??

[Bogertophis]

Two water bowls are always available and clean, One is on the warm side and one on the cool.

Humidity ranges from 60-70℅
I haven't seen her drink, so it could be possible she's dehydrated?

Her eyes aren't sunken in, and it's strange how it's only a small portion of her body is "dimpled"

I agree, it doesn't make sense to be dehydration, as that wouldn't be so localized. Just trying to "brain-storm".

It almost looks to me like her skin got pinched (squished) in that area. What's in her world that could do that- anything?
