This is caused by the local dermal nerve not growing well, because the cesarean section needs to cut the skin and enter the abdomen layer by layer, and after cutting the skin, some dermal nerves will be severed, which will cause numbness around the wound during the healing process because of the slow growth of the nerve. Therefore, you can promote the recovery of the nerves by applying local heat and physical therapy. At the same time, attention should be paid to the diet, such as appropriate intake of high quality protein with low fat and low cholesterol content, such as fish and shrimp, leaner beef and mutton, which can facilitate the recovery of the nerve. Also appropriate intake of fruits rich in B vitamins and C vitamins, such as kiwi, apple, banana, duck pear, etc., to promote the growth of nerves. You can also eat more foods rich in unsaturated fatty acids, such as walnuts, peanuts, sesame, etc. In most cases, the numbness can be gradually relieved in about six months after the operation.
