I have had a severly injured snake, actually i still have her and shes doing great. When she shed all her wounds opened up and looked like that. The vet did nothing for us, actually might have made it worse, we then consulted the reptile vet from the local zoo and he referred us to our friend who runs the local reptile store. So yea vet is not always the best anyway. I agree keep her cage sterile and see if you cant get ur hands on some antibiotics to prevent infection. Maybe consult a vet on the phone if physically visiting one is not an option. But like I said in my situation the vet did nothing and I can get all the meds I need through my friend.
