After a patient has surgery for a herniated lumbar disc, there is usually no recurrence. When a lumbar disc herniation is treated surgically, the herniated nucleus pulposus tissue is usually completely removed, so the disc in that segment is not prone to recurrence and the symptoms of nerve compression by the nucleus pulposus tissue in that segment will not occur again. However, after surgical treatment of lumbar disc herniation, the stability of the lumbar spine will be affected to some extent. If the patient does not insist on lumbar back muscle exercise and weight control to reduce the weight of the lumbar spine after surgery, the lumbar disc tissues of the adjacent segments are also prone to degenerative changes, eventually causing lumbar disc herniation, which will compress the nerves and lead to lumbar pain and leg pain, and the patient himself cannot accurately identify the segment of the lumbar disc herniation and will think it is a recurrence after surgery. At this time, a timely visit to the hospital should be made for examination to confirm the segment of the herniated disc and early treatment.
