I told my doctor about my stress incontinence; she checked and said I had a bladder hernia. She said it's common among women who have had children, but I never had children.
Isn't it also better known as a prolapse or a cystocele? I have a problem as well. It is my understanding that it is not just from having children. It can also be caused by over lifting. the walls of the vagina become weakened and let the bladder herniate into it. If you do a search for cystocele you will find a great deal of info.
I did a search; amazing all the info that's out there.
