Normally, the stitches of a normal delivery do not hurt for 3-5 days, but it depends on the physical condition of the mother and the specific circumstances of the delivery, and needs to be analyzed on a case-by-case basis, so it is not possible to generalize. The natural delivery of the fetus through the vagina is the most common clinical delivery method. During normal delivery, if the labor is not smooth, such as when the fetus is large and difficult to deliver, a lateral perineal incision may be performed to make a diagonal incision in the perineum to facilitate the smooth delivery of the fetus. After delivery, the incision will be sutured. As the operation is carried out under local anesthesia, the mother usually does not feel any pain, but after the anesthesia has worn off, coupled with the contraction of perineal muscles, local edema and other reasons, the mother will feel obvious pain, which will usually be significantly improved after 3-5 days. After delivery, you need to pay attention to personal hygiene, try to use warm water to wash after urination, and then use iodine to disinfect, so as to avoid wound infection, and pay attention to rest, do a good job to keep warm, avoid getting cold and flu.
