Hey, we need a closeup of that vent area and also a closeup of the whole animal. What are the other specifics in your setup and husbandry? What morph is this? Male / female? Weight ? Its hard to tell right now. Prematurely it could be just a vent irritation with some localized swelling. How long has the animal had this? Worse case scenario, prolapsed cloaca or infected hemipene if male. Either way start implementing some immediate changes to the enclosure as you already have. Switch to paper towels after you disinfect that enclosure with a 1:10 part solution of bleach to water and rinse the enclosure well before placing him or her back in. Light warm soaks in separate tub with betadine in the water so the water is tea colored. This is just a preliminary basic treatment. Consider a herp vet soon. Consider Neosporin ointment in between the betadine soaks. Good luck. Stay in peace and not pieces. A.C.![]()
