Help from anyone that has treated bad scale rot (photos included)

Hey! I have been BUSY (with her, and with our other animals in general), and I will sit down and write out a good response to this thread... But I just want to clarify up front that this snake HAS been to a vet, and stayed there for several days. I am not just doing this "bathroom cabinet" doctor style with internet help. Granted, I am very concerned that the vet did not do a good job, and instead of saying "I am not experienced with snakes, here is a reference to someone that is" they did little, charged a lot, and gave limited advice. Through our local herp club I have a recommendation for a better vet, but I wanted to clarify, she HAS been to a vet.
