Hello, I Am Writing For My Wife. She Is 23

Hello, I am writing for my wife. She is 23 weeks pregnant. She has a mass that hanging out from her anus. She had it for quite some time. It is hanging from inner side of her rectum don't know how long and where the starting point is. The end portion of it is very much seen outside. It gets sometimes very painful and burning. It sounds like a skin tag. She cant sleep or sit or do anything because of the discomfort caused by pain. Is there any temporary medicines like ointments that can be applied which will not harm the baby.
