I'm pretty sure it's not yellow fungus as my Titan had it and it never looked like that. I have a friend who has a uromastyx who had burns all over. Quasi has now healed but the scales of the skin that were burned presented exactly like your girl. I would think honey would help, manuka would be the best has it does have great healing properties, but as Diane said, put it on at night, every night so she's not under her lights. Is there a way to lower her basking spot, maybe put that log somewhere else and have her on his hide instead, or somehow lower that log.
Have you taken her to an exotic vet? That's what I would do. The only way to determine for sure if it's not yellow fungus is a biopsy, but they cost alot. Titan was burned on his head and once the burns healed (it was from a heat lamp that fell on him) they presented the same way. The vet is just a suggestion, I know they're expensive but it's the first thing I tend to do when one of mine presents something strange.
So try the honey but at night when her lights are off, see if there's any change in a week. Then go to the vet to have it properly looked at.
The top of Titan's head when I first got him. He was about 6 mo old at the time. This was in Apr/13 and he was diagnosed in Oct/13. Your girl would be presenting more than just this scarred area if it was Yellow Fungus, it's a very fast disease and always fatal. Titan was put down on Dec 19/13 because by then it was all through and over his body. So I'm pretty sure, if this presented in June of this year and we're now in Nov, that it's not Yellow Fungus.
April/13
Sept/13
You can see in the 2nd picture how the lesions on his head got worse, not long after this picture was taken, I took him back to the vet. She thought it was a bacterial disease so gave him anti-biotics, that made them get worse so we did a biopsy & it came back positive at the beginning of Oct. You can see it doesn't look anything like what your girl has.
