M.S.
I was recently in your position, waiting to get in to see the doc, and wondering what was going on. I also have prolapsed uterus, bladder and rectum..yikes! It's very uncomfortable at times, but "nothing that can't wait," according to my doctor. After seeing a doctor, I was told I had three options: do nothing, have a hysterectomy, or try something called a pessary. Obviously I'm not sure, but I am guessing you would have the same three options.
I also went to see a Pelvic Floor Physical Therapist at Mayo Clinic, which seems strange but was very helpful in making me feel like I was doing something. I'm not sure yet if the exercises are helping, as I haven't been doing them long.
I was initially quite opposed to the pessary, but may end up going that direction after all. At least it could be a short-term fix, and maybe in a few years when my little ones are older, I would do surgery. I hate to say this, but my doctor says it won't get better. I can either maintain where I'm at, or it will get worse. Some on-line research suggests otherwise, which is one reason I'm not terribly anxious to do surgery right away.
Good luck. I would be interested in hearing about your doctor's advice.
