Zuko did see a vet. The vet was the reptile specialist in the area that all other vets in the area refer to.
Treatment was:
clean paper bedding
daily soaks and a light scrub of the area to get the necrotizing skin off
very light application of silver sulfadiazine cream
Vet said:
'It will take a very long time to heal with some scarring' at the original visit
'Should do alright, just wait and see' is where we are now
I switched the snake back to coconut fiber bedding two weeks ago as the wounds are all closed and there are no scabs left. Zuko seems much more relaxed and is able to maneuver a bit better on this bedding than on the paper towels. I was hoping maybe that would further jumpstart instincts. But just seeing the snake moving about makes me happy.
The first assist feeding had a bit of fighting, but the other two were a bit easier. I don't press the feeder too far, just enough for the teeth to hook and for instinct to kick in.
I don't know the internal extent of the injuries, but urates were still passed regularly and 3 very small fecals as well. 1 not long after I got the snake in my care and the other 2 after the 2nd and 3rd assist. I take this as at leas a good sign things still work down there.
