During vaginal delivery, most women will have a perineal laceration or have a lateral perineal incision, which requires stitches, and the lumps at the stitches appear after the stitches are closed because of the formation of scar tissue in the area. The formation of scar tissue is related to a woman’s body constitution, most scar tissue is not obvious, and a few are more obvious because they are caused by a scarred body. Perineal scarring is more noticeable within a year after giving birth, and will gradually decrease afterwards. It has no effect on your sex life and menstruation, and will not affect your second birth. There is no need to be overly nervous, just pay attention to perineal hygiene.
