Postpartum caudal spine pain can be treated by the following methods: First, baked electric therapy or far-infrared therapy or ultra-short wave therapy can be used, which can significantly improve local blood circulation, reduce the inflammatory response and relieve the clinical symptoms of caudal spine pain. Secondly, if the patient has caudal spine pain caused by lumbar disc herniation, bed rest is needed, together with lumbar back muscle exercise and lumbar spine traction treatment, which can improve clinical symptoms. If there is a serious lumbar disc prolapse into the spinal canal and compression of the nerve, resulting in continuous and severe pain in the caudal vertebrae, conservative treatment is usually ineffective, and surgical treatment needs to be considered to remove the herniated nucleus pulposus tissue through surgery and completely release the nerve compression in order to relieve the clinical symptoms of caudal vertebrae pain. Therefore, patients with postpartum pain in the coccyx must be diagnosed and treated as soon as possible in order to get complete relief of clinical symptoms and recover from the condition.
