Cupping has been getting enrofloxacin 8 hr soaks each night for a swollen ‘knee.’ C&S showed aeromonas, klebsiella, and proteus hauseri. She first got a pink bump near her rear end and today has an orange bump on one leg. Could this be a parasite? She seems happy, is eating and defecated a few days ago. Photos show the pink bump and her knee. She does look better than she did before the enrofloxacin.
