Hopefully this all resolves...just be patient. Many snakes getting antibiotics won't eat until done with all that, & you might also consider adding snake probiotics* to help her digestion recover- since antibiotics destroy the good & bad bacteria equally well. *Rather than dusting them onto a f/t rodent (which can change the scent of the prey, & most will fall off rather than be ingested anyway) I'd install probiotic powder into the rodent's mouth, then push it closed again before feeding.
