Baytril is not without harmful effects, and especially if it's the wrong antibiotic to begin with. Without lab work first, it's just a shot in the dark, no pun intended.
I agree with Cheesenugget...keeping pets for which you have NO available vet care isn't a good plan for either you or especially your pet, sorry to say. Neither is depending on the internet or social media sources...it's irresponsible to prescribe treatments for animals NOT seen, & advice given by those untrained can often prove to be dangerous, even deadly, for your snake. Veterinarians, like other doctors, take an oath to "first do no harm" and quack "cures" like using Vicks (TOXIC!!!) or eucalyptus oil (toxic &/or irritating at best) are NOT the right answer.
