What happens during a c section? Is your muscle cut and re - tied? Or do not all doctors re- tie the muscle after cutting into it?

Not cut. Your abdominal muscles are not cut during a standard c/s. There is a natural vertical midline separation of your abdominal muscles. Entrance is made thru this natural separation and the muscles are temporarily pushed open to each side, allowing the surgeon to enter your abdominal cavity and get to the uterus.
