The reason why some mothers experience pelvic pain and hip pain after giving birth is considered to be caused by pelvic separation during pregnancy and labor. However, after the pelvic repair treatment, the symptoms of hip pain appeared, the reasons mainly include: First, the mother does have a more serious pelvic separation phenomenon, but the pelvic repair treatment that has been carried out is incorrect and ineffective, and the symptom of hip pain has not been effectively relieved. Second, the root cause of maternal hip pain is due to severe osteoporosis caused by localized bone pain, or because of lumbar disc lesions compressing the sciatic nerve, causing hip pain. Pelvic repair treatment alone cannot provide effective treatment. In this case, it is recommended that the mother go to a regular public hospital as soon as possible for further examination and treatment after a clear diagnosis.
