After the second child cesarean section, because the nerves and blood vessels were cut off during the surgery, the nerves are not yet connected after the wound heals and the blood vessels have not yet formed a collateral circulation, so there will often be pain, itching and numbness, which is a normal phenomenon. However, under normal circumstances after cesarean section, the painful symptoms of the incision will slowly ease after 24 hours until they disappear naturally. If there are still painful symptoms after the stitches have been removed for more than 7 days after surgery, you need to be examined by a doctor to see if there is bruising and incision infection, and then actively treat the cause as soon as possible.
