Hi there. Make sure you see Urogynecologist for treatment options including any prolapse operations as they are the prolapse specialists. I wish you will with this surgery and pray you have your operation as promptly as you hope.
Have you asked to see a womens physiotherapist for help with strengthening your pelvic floor? You can also ask to have a vaginal pessary fitted to support your rectocele etc if you have to wait for a pop operation so maybe consider this as well.
Good luck and let us know how you get on
I had the surgery oct 28th so far so good! Btw yes with a urogynecogist
