Our 4.5 month old EB was just diagnosed with the same thing last week. We went to two vets and they both said to just leave it be for now. Two days in a row he woke up with blood on him from where he was bleeding. It was pretty scary. The vets said that if it gets worse they can either put the prolapsed part back inside and put in a small suture but that with this treatment the issue often reoccurs. The other option, if it gets worse, would be to cut off the prolapsed part through surgery. In the last couple days it seems to be getting a bit better so I'm hopeful that we won't need surgery. Please keep us posted on how things go.
