Does anyone know the difference between a mild scale rot and a scale burn? My ball python appears to have a pink belly and it could be one of those because I was new to owning a pet and i really didn't know how to take care of it, I had a heating pad, a thermostat and a hygrometer all together but what I did was try to get the temperature of the air itself in the tub to 30 degrees C using the heating pad only.. I did have a substrate but it could have buried itself under it..I also noticed that the humidity used to get up to 95 percent.. any who, now that I got it all set up, adjusted the temperatures and humidity percentage, i'm still concerned about her red belly.
It has a few black spots on it but im not sure if that's just how it's supposed to look like or not.. and the entire belly is pink and it has one small part which is where the neck is and it's redish, I'm worried because I did take her to the vet and he didn't seem to know anything about it but he still managed to give me a cream to use for 2 weeks. I also noticed that some scaled ontop of head were peeling off, about one or two but that might just be because it didn't shed it's head or eye caps when it shed it's skin although it all came out in one piece :S, I've also noticed that the eyes are kind of dull/grayish in colour but I still don't think it's time for it to shed seeing as the rest of her body is light in colour and not dull.

Any answers would greatly be appreciated ( Oh and I used to have under bed pad's as a substrate but I switched it to wood shavings last night)
