That's A better view. Unfortunately he is going to need internal antibiotics from a vet. I think anesthesia is extreme at this point but miss Skittles was thinking it may be a abcess. I don't think its that type of infection but whatever it is its spreading. I personally have not had a Cham with mouth rot so I have no experience with it. Its not just on his lip, its on his chin as well. I am not sure what the yellowish bump is at the rear of his lips either. Btw he is stunning! Look up mouth rot on this site and see what other Cham owners have dealt with. where exactly in Hawaii are you? Which island and town? Also I use Bauch and Lomb saline solution for sensitive eyes when I flush anything. Even the eyes. Then use a qtip and gently try to get the dried blood off then use a dry stop to dry it off before putting the topical ointment on. The Neosporin without pain relief additive is a light weight topical use small amount incase he digests some. The bigger issue is to seal it so you stop the spread and keep bacteria out. I do not think this is an infection from an injury. Am thinking fungus, virus, bacteria infection. did you try to find a reptile rescue or try bird rescues too. Keep calling someone may point you in the right direction to get help you can afford. The universe brought that sweet boy to you so tell the universe to help you find help.
