I was in agony after my crash section. Eye rolling, sweats of agony, and I've had abdominal surgery before.
I got a huge incision, they cut through nerves muscle and blood vessels and left me with huge adhesions with trapped nerves and clumps of scar tissue internally wrapped around my innards. Lost a lot of blood too.
Make sure they use a cauterising blade. Make sure you get the smallest incision possible and make sure they stitch you back carefully. Make sure you have a good haemoglobin reading before you leave the hospital.
I was in agony even two years later, couldn't lie on my tummy until I had a years physio and couldn't bear any pressure on my tummy until my physio broke up the adhesions (manually, with was agony in itself). She made such a mess of my uterus I've been recommended a hysterectomy. Not really what you're expecting when you're expecting.
As you're having an elective, you may be lucky, but do ask your surgeon to be careful. Remind her you want a life after the baby, and you expect to be able to have a normal, pain free life after she's done her job.
My surgeon was a crack handed butcher, with minimal empathy and even less skill. She couldn't have cared less about me and my life after the birth, as a human being, a wife and a mother.
I have my fingers crossed for you and your baby.
Good luck!
