Female patients often experience low back pain after giving birth, and the common clinical causes are mainly the following: First, lumbar muscle strain, as the huge fetus and uterus of women during pregnancy can cause continuous stress on the muscles of the lumbar back of pregnant women, and the performance of lumbar muscle strain. Patients need to take sufficient rest, massage physiotherapy for the lumbar back muscles, hot amoxicillin packs for external application, moxibustion strips for fumigation, and blood circulation cream for external application, which can improve the blood circulation of the lumbar back muscles and reduce the local pain symptoms. Second, due to the continuous force on the lumbar spine when women give birth, they will develop lumbar disc herniation, which will manifest as symptoms of lumbar pain after giving birth to a child. The patient can improve the lumbar spine magnetic resonance or CT examination to clarify the severity of the lumbar disc herniation, and if necessary, perform surgery to relieve the nerve compression symptoms, thus improving the performance of the patient’s lumbar pain.
