The lumbar region is an important weight-bearing structure of the body, including the lumbar vertebrae, intervertebral discs, numerous strong paravertebral muscles, ligaments, and rich neurovascular tissue, and pathological injury to each part can cause painful symptoms. As mentioned above, according to the etiology of low back pain, it can be divided into atopic and non-atopic, and the majority of patients have non-atopic low back pain, i.e. low back pain of unclear etiology. The majority of patients have nonspecific low back pain, i.e., low back pain of unclear etiology. Atopic low back pain includes numerous diseases such as degeneration, tumor, and infection.
In addition, simple intervertebral disc disease also includes a variety of conditions such as abnormal nerve distribution within the disc, mechanical pressure changes within the disc, and epidural inflammation. Therefore, low back pain is by no means equal to lumbar disc herniation. In addition, imaging reports of herniated discs are not always accompanied by symptoms of low back pain.
