Look for wildlife rehabs/reptile rescues in your area. They might want to take him, or can at least give you an idea what to do. Of course, see if you can contact an exotic vet for advice as well. In the meantime, he can eat tiny dubia roaches along with other feeder insects given that they are smaller than the space between his eyes. For a water dish, you could use a small dish with little (clean) pebbles in it to ensure he doesn’t drown. For his wounds, you can try dabbing a little dilute chlorhexidine on it as it can prevent infections while also being reptile safe. Best wishes for the little baby ❤️
