Reading your posts- I'm thinking some form of rectal prolapse?? Your symptoms sound awfully similar to mine. Currently sitting here with an aching bumhole. Had colonoscopy & rectal exam and nothing was found. I also ran it past my gastroenterologist at my follow up appointment & she said NO flat out. It was only when I asked my poor partner to take a photo after a BM did the specialists agree it was a prolapse! Mine still hurts even when it is not protruding... Maybe you are dealing with something of the like??
I don't know how to use this, but I need to say that 30%of women that delivered their babies vaginally could suffer from a rectocele! My symptoms was " constipation"... Having like a tennis ball in my rectum.... And of course the famous IBS... I hope this could open eyes of OBGYN, Gastro to recommend to see Rectum Specialist!
