In outpatient clinics, we encounter many patients with CT or MRI data asking their doctors, “What should I do if the test results show a lumbar disc herniation?” We need to clarify the difference between lumbar disc herniation and lumbar intervertebral herniation. The Chinese character “症” contains two parts: the morphological side “疒” and the vocal side “正”, so there must be a “disease” in order to be called “症”. Therefore, there must be “disease” before it can be called “disease”, and without “disease” it cannot be called “disease”. The so-called “disease” or “disease” is what we often call clinical symptoms. The typical symptom of lumbar disc herniation is back pain with radiating pain in the lower limbs. A herniated disc is classified as: bulging, herniated, prolapsed, or free. Many normal people who have CT or MRI examinations will have bulging, herniated or even prolapsed or free discs, but the majority of people have no clinical symptoms or few clinical symptoms. The reason is that most of the lumbar disc herniation occurs in the lower lumbar segment, and because of the wide spinal canal and the cauda equina nerve in the spinal canal, the herniated disc tissue has less or no compression on the nerve root, or the cauda equina nerve has tolerated the herniated tissue, so there are no clinical symptoms or the clinical symptoms are mild. In such patients, no special clinical management is needed, and the herniated disc is only an imaging change. We should make it clear that the doctor is treating the disease or condition and not the imaging changes.
