Ok, I really need help here, badly. I was inspecting my baby doll today, a young ball python, about 6 months old. He is towards the end of his shed now and just scraping the old flesh off, and as I turned him over to see the rest of his skin, I noticed there was an unusual bulge at his cloaca. It is a light reddish mass, appears filled with fluid, and despite my books, the only thing I can find that is close to what I am looking at is possibly rectal prolapse or prolasped hemipenes. I know in the end I will probably have to take him to the vet, bt I want to at least get an idea of what the hell is going on, pardon my language. Any help, suggestions, or general knowledge is very welcome here.
