You might want to make an appointment with your gynae and see if s/he can take out your stitches earlier. I have 2 kids, both times also need stitches and both times had a bit of swelling due to too much movement so the stitches were too tight 😅 Once my gynae released the stitches the pain was a lot better and can move more freely.
You will not require new stitches. Two times being a mum and stitches of vaginal area twice 🤭🥲😅 You can try sitz bath using epsom salt with warm water and do twice a day for 15 to 30 mins. Alternatively, use epi-kool pad and let the pain be numb.
