With a daily use of neosporin and anti fungal cream I am not surprised that scales are falling off. Oil based cream will loosen up scales.
I am curious what was the "expert" diagnosis? How much hands on experience does he have?
From this description the proper course of action would have been, cleaning the area, applying neosporin once and let it be until next shed and even that was probably unnecessary. Other thing to do would have been to replace the substrate with newspaper or paper towel and keep it clip and dry.one small spot on her belly she was bleeding under a scale
