Whether the stitches will hurt after surgery depends on the site of the stitches and the growth of the wound at the stitches. If the nerves in the surgical site are less distributed and the pain sensation is less sensitive, the stitches will not hurt much after surgery, for example, the stitches in the extremities and the chest and abdomen will not hurt so much. However, the nerves in the anal area are more sensitive, so if the stitches are removed in the anal area after surgery, the patient will feel more pain. If the time to remove the stitches is extended for a long time after the surgery, the scar at the surgical incision will cover the stitches and it will be more difficult to remove the stitches, so the time to remove the stitches after the surgery needs to be strictly controlled, neither too early nor too late.
