I had this procedure too, twice. The first time the stitches weren't placed correctly and they left me too tight.
The second one left me looking and feeling far better.
I have lots of advice! :
You need to follow instructions afterwards for keeping clean, I rinsed with tea tree in water or salt water to avoid infection. Pelvic floors excercises are important too to keep blood in the area to heal it.
If you take Arnica before and after to speed healing, and I also heard that taking Calendula homeopathy in the days before and after helps to reduce the risk of infection. Double check with your surgeon if you do these.
www.ainsworths.com is a good source of guidance with this.
Depending on how much tissue is taken, you may or may not be offered a set of dilators to take home and use to maintain your "passage"! I don't mean to frighten you and you'll probably/hopefully never know what I'm on about but I'd have preferred to know in advance as they look like dildos !
Lastly I hired a Valley Cushion from the NCT to sit on when I couldn't lie. It's got a groove down the middle to reduce pressure on your bits. I found it essential. Having sat on a rubber ring after the birth and first op, I was later told they're not good for you, as they put too much strain on the area that hangs through the middle...
I'd also say to make sure before you go home they give you a direct number to ask any questions you may have once home.
Good luck, it is sore but not as bad as after childbirth as you're expecting it, and keeping on top of your painkillers helps loads. My physio told me not to lift anything heavier than a kettle of water for eight weeks so get those favours in with friends and family to help with your little one!
