Go to any natural health store and get some collodial silver. It wont take much, and use it on him several times a day. I mist the injured area, add some to the water, and be sure he cannot get into the water or stay wet for long. Ask them the most sold brand, there can be many, but I like Sovern Silver(sp) if I dont have any made. I have my own silver maker now, I have had such great luck with it. Do not handle the snake any more than you have to, he needs to spend all available resources on the healing process and moving makes stress and burns calories. If there is a dog/cat vet that you have a rapport with you might get them to sell you Baytril but you will need to research how you may administer it and be confident but if not better to not try it at all. There might be other Herp people locally that are willing to help you, maybe even take him for a while in a better effort to save him if they have experience in this area. This injury is certainly a life threatening one, compounded by the lack of appetite. I wish you were closer to the vet clinic I work atGood luck!
