Adhesions can cause serious pain but vaginal bleeding I am not so sure and you are right they will not show
on any scan you get.
I have Endo with Adhesions and I had rectal bleeding but the adhesions were
on my bladder, bowels and ureters. I could feel a lump under my 3cm scar and it was causing a bowel obstruction.
I am wondering if it some sort of organ prolapes but since you said the CT showed nothing maybe it isnt?
So to be clear you have everything removed even your cervix right?
