YBR i just wanted to reassure you that prognosis isn't grim. as lukewarm says, it will get better either way. to give you an alternative story to restitching: my stitches starting falling out at about 9 days postnatal, and were all out by the time the mw saw it at 10 days postnatal. i had a 3 inch episiotomy, which was then a 3 inch open wound. they didn't want to restitch. i was in agony, and lots of painkillers. anyway, instead of a restitch i had cauterisations, ended up having this 4 times, and also i had to have a small amount of granulation cut away under local aneasthetic. oh, and on day 16 postnatal before all that, they ruptured some granulation tissue with some guaze. anyway, through this process of managing the granulation tissue, i did not have to be restitched, and the wound eventually healed and the pain eventually subsided (it took months though)
i did a lot of research and never heard of sugar paste, that's interesting. i did however hear of manuka honey applied to the wound, salt water baths, and tea-tree and/or lavendar oil baths.
wash the area after you go to the loo each time, you should keep it really clean to avoid infection too.
get as much air to the area as you can- sleep without undies if possible.
there are lots of threads on this, its surprisingly common, you can probably search for them to get a range of stories.
