Usually, lumbar disc herniation is called lumbar disc herniation, and the difference between lumbar myofasciitis and lumbar disc herniation lies in the differences in etiology, clinical manifestations, and examination methods. 1. Etiology: lumbar myofasciitis is mainly related to cold and local chronic strain. On the other hand, lumbar disc herniation is usually caused by long-term overloading and degenerative changes of the annulus fibrosus. 2. Clinical manifestations: lumbar myofasciitis is mainly manifested as pain in the lumbar back, limited lumbar spine activities, and does not cause radiating pain in the lower limbs, lower limb weakness. On the other hand, lumbar intervertebral disc herniation mainly manifests as radiating pain and numbness in the lower limbs, as well as weakening of muscle strength, and even causing muscle atrophy. 3. Examination: lumbar myofasciitis does not require special auxiliary examination, and can be diagnosed through physical examination and medical history. On the other hand, lumbar disc herniation usually requires CT scan and MRI to support the diagnosis. In addition, it is recommended that patients suffering from lumbar myofasciitis and lumbar disc herniation go to the hospital in time to avoid delays.
