UPDATE:
Dipoiios had been very sluggish both in and out of the cage tonight, so when she crawled up to the cage door and slowly poked her nose through, looking directly at me, I knew she needed something. Badly.
I took her out and took a peek at her underside, noticing that there was a bit of discharge at her opening, but that it had dried. It suddenly dawned on me that this was very, very bad, and needed to be dissolved right away. With warm water and a towel, I gently cleared the dried discharge, and all of a sudden she started -oozing- quite a lot. This time, it smelled; somewhat foul, but not overpowering. Since that, I've been gently wiping at the discharge with a damp towel for her to ensure that it doesn't crust over like that again, as she doesn't really have the strength to groom herself in that area at the moment.
It seems as though she is hugely relieved though, because the first thing she did was just lay down, and close her eyes. I can't imagine all of that pressure (let alone from toxic fluids) was comfortable at all. She seems to be breathing easier as well, and I'm extremely glad I didn't go to bed when I wanted to, or I fear she would have gone septic in the night.
I am not a fan of these close calls =\
