Thank you both so much! I was hoping it might be something small seeing as it healed (?) so quickly, but still I worried she might have the start of something serious that might have needed some form of special attention. I'll keep a close eye on her in case it was substrate or something got caught in there for a bit, but hopefully she was just leaning against her log at a strange angle.

Also, good to hear your gecko recovered just fine! I'm grateful that despite accidentally munching on aspen once or twice during feeding (she enjoys dragging her rat off of her hide and through the aspen...), she's never been injured by it before this possible time.

Again, thank you both for your advice! It's a relief to know she seems to be okay.
