Although the pain was reduced, it was still unbearable and has not been cured yet. Can you help me think of a solution? Can you help me think of a way to treat it? Thank you! Luo Min, Department of Pain, China-Japan Friendship Hospital of Jilin University Luo Min, Department of Pain, China-Japan Friendship Hospital of Jilin University: Hello! First of all, I would like to express my sympathy for your situation, and at the same time, I would like to express my gratitude for your trust! Due to the continuous improvement of modern medical care and the rapid development of science and technology, the level of diagnosis and treatment of many diseases has been improved unprecedentedly. In particular, the treatment of lumbar disc herniation has been perfected day by day, corresponding to different periods and different types of lumbar disc herniation, its surgical methods are different, such as: open surgery, minimally invasive surgery and so on. Among the open surgeries, total laminectomy, hemilaminectomy, and windowing are performed in conjunction with nucleus pulposus removal, and some patients need to undergo intervertebral bone grafting and internal fixation with a nail-rod system due to the combination of lumbar degenerative disease or lumbar spine instability at the same time. Minimally invasive surgery, on the other hand, includes methods such as: mesoscopy, radiofrequency, laser, and collagenase. Each procedure has its specific indications. Since your description is not very detailed, it is only known that you underwent open surgery; based on the symptoms you described, it cannot be ruled out that you have a combination of a complication that rarely occurs after lumbar disc herniation: intervertebral space infection! The main manifestations of this complication are: persistent intolerable back pain, which is usually not accompanied by fever, and white blood cells may not be high; however, physical examination reveals lumbar plate-like hardness with obvious lumbar percussion pain, rapid blood sedimentation, high C-reactive protein in laboratory tests, and hyperdense changes in the lesion area may be seen in ECT examination. In terms of treatment, anti-inflammatory and lumbar physical therapy were the mainstay in the past, but the efficacy was poor. In the past two years, we tried to treat this disease with lumbar minimally invasive methods, and the efficacy is very precise, which can be said to be another application of minimally invasive technology in the field of orthopedics. You can come to our pain department if you need help. I wish you a speedy recovery!
