I was going to link to the MN webchat on prolapses but Terry has beaten me to it 
I'm a prolapse veteran, sadly. Gave birth ten years ago, fourth degree tear, wasn't repaired properly, had NO idea about prolapses and suffered in silence with incontinence issues as I hadn't had adequate follow up. Fast forward and following a completely embarrassing episode on holiday where i totally lost control and wet myself, a GP diagnosed prolapse and referred me to a Urogynaecologist. I had bladder and bowel repair and perineum rebuild (as I only had a sliver of scar tissue that masqueraded as a perineum). Sadly that surgery failed and I was re-referred.
Whereby after seeing a colorectal team, they discovered I had a ruptured sphincter. Hardly any muscle. The recommendation was straight to permanent colostomy or risk a repair. I opted for the latter. It may well be that I'll have no option other than colostomy later on but, for now, the sphincter repair is holding Further surgery next year to re-do prolapses and probable hysterectomy.
The MN webchat is Jan 23rd and anyone wishing to join APOPS will find an informative, unbiased and supportive group.
I have suffered. And I'm fucking furious that this topic isn't being discussed more, researched more, screened more and of paramount importance, taken more bloody seriously other than to just "get on with it" and "it's to be expected" and the like.
Awareness CAN lead to prevention. Things like massaging perineums, optimum birthing positions and so many more.
Fuck, I'd have even settled for even KNOWING it existed FFS.
