Theres a real fancy trick this old old old old old reptile breeder once taught me. With prolapses, cold water, put back in, and put a snoopy bandaid on it. Hmmmmmmmmmmmm it works, not need for stitches etc. Bandaid does that same thing only you can do it.

No matter how its treated, you now must find out if your the cause, or it was pre-exsisting. good luck
