Pessary and Protruding Cervix

Hello everyone, and thank you for being available!
My question: If using a silicone pessary has actually worsened my prolapse -- I went from having cystocele and rectocele to very suddenly having my cervix protrude -- do I have a chance of healing without surgery? I ask this because of something in Christine Kent's wonderful online video "The Whole Woman Solution to Pelvic Organ Prolapse and Urinary Incontinence." Around 2 minutes into the video, she mentions that as a result of hysterectomy, it's possible for the whole vagina to invert and balloon out, bringing the cervix with it, and that this "can only be treated with serious reconstructive surgery." I've never had a hysterectomy, but my prolapse looks a lot like the photo shown at that point in the video. I hope you can tell me I still have a chance to manage this degree of prolapse and possibly reduce it a little!
Details that may help you respond:
-- My "balloon" and cervix appear only when I'm standing, usually after midmorning or noon, earlier when I've gone out for a brisk walk or have been lifting/carrying things. They retract when I sit on a firm surface or lie down.
-- The cervical protrusion started very suddenly after a short but intense illness that included internal pressure and massive diarrhea.
-- History: I'm 70. I've had one child, vaginal birth, at age 39. Afterward I had incontinence and felt what I now know was prolapse, but the ob/gyn was dismissive: "That'll go away." It never entirely did, but I wasn't assertive enough to mention it again. I first noticed the protruding cystocele and rectocele around 10 years ago. Around 4 years ago, I finally gathered enough courage to tell my doctor about it. Instead of scheduling the suggested mesh sling surgery, I started Mayan abdominal massage (ATMAT) and experienced significant improvements, learning a lot about my body and reconnecting with it emotionally in the process. Still, the prolapse is gradually worsening. I got the pessary 9 months ago and use it maybe 2-5 days each month, for about 8 hours per day.
-- These yoga postures feel like they bring all my pelvic organs back into place: "cat/cow" (especially "cat"); "puppy pose" (knees and chest on the mat, knees spread wide, big curve in spine); and sometimes "downward dog" and "shoulder stand".
-- I've bought and hugely appreciate Christine Kent's "Whole Woman Fundamentals" video bundle.
Thank you in advance for any encouragement you can offer!
