I went and saw my GP at about 4 months post birth as I felt something wasnt right. He refered me to a gyno, who confirmed I was right (which was a relief!) - I had a Stage 2 recto-enterocoele and a stage 2 cystocoele, plus extensive scar tissue - all of which eventually needs surgery to repair.
The gyno discussed how my labours had gone, what our plans were for further children, how much discomfort and pain it was causing me, and how I wanted to proceed. As there was a high chance of needing surgery again after one or two more kids, we decided on me waiting until we have finished our family to go ahead with that. She was very supportive though and had I insisted, would have supported surgery now even if it meant more surgery down the track.
DD2 is now 1 and I have to say Ive seen a huge improvement in the last 3 months. It still needs repairing but I can live with the problems (the main one is discomfort during sex). I dont do anything in particular for treating the problem. I was given pain pills but more for the scar tissue I think - I never really used them though.
I think the options depend on the degree of damage and the problems it give you, so theyll go over everything with you.
Worth noting - it was suggested to me due to the nature of my first two labours, the damage caused during DD2s birth, the potential for further damage with natural labour, and the size of my babies, that I have c-sections for any future kids. If you are planning more, its worth discussing - its not a definite with prolapse, in fact she told me she would help me have a natural birth if I REALLY wanted to go down that route again, but for me it was weighing up the benefit of vaginal birth compared to the risk of irriversible damage and risk to my girls if my labour was the same.
All the best for you appointment, hope it goes well for you
