Oh wow! Just now seeing this. That sounds EXACTLY like a brown recluse bite. So scary! Continue what you are doing and watch her. I know those bites can kill tissue ( like the scooping out you mentioned). They can also cause neurological issues. If you see any signs of that, get her back to the vet asap.
Praying!!
