The pain in the place where the anesthesia was given after the cesarean section, that is, the pain in the mother’s lower back, many women will think that it is caused by the anesthesia, but in fact the real anesthesia that causes the pain in the lower back is very rare, because the anesthesia needle is given in the gap of the lower back, not poking on the bone, so it will not cause the pain in the lower back. This pain is mainly caused by the factors of pregnancy and childbirth. After pregnancy, with the increase of hormone level in the body, women will lead to loosening of joints, ligaments and even changes in the lumbar spine, and some symptoms of low back pain will occur. Often, those who have low back pain after giving birth already have certain symptoms in late pregnancy, only to be aggravated after giving birth, so many women feel that the pain is triggered by the postpartum period, but in fact the cause of this disease has been buried during pregnancy. In addition, postpartum, due to some mothers breastfeeding in the wrong position, or sitting or lying down for a long time, may aggravate the back pain.
