The most common cause of lumbar sleepiness and leg sleepiness is due to lumbar disc herniation, where the herniated disc or nucleus pulposus compresses or stimulates the nerve roots, resulting in radioactive pain or soreness and weakness of the muscles in the innervation zone. If the nerve has been compressed for a long time, ischemia, degeneration, necrosis, etc., it will lead to muscle atrophy and weakness in the innervated area. In the above cases, CT, or MRI examination of the lumbar spine should be improved to clarify the direction and degree of protrusion of the disc, and then choose appropriate treatment measures. It may also be lumbar spine tuberculosis or lumbar spine tumor, the lesion invades the lumbar spine bone and the surrounding soft tissue, which leads to soreness and weakness in the lumbar back and restriction of activities, and if the nerves are stimulated, it will lead to soreness and weakness in both lower limbs and difficulty in walking. In this case, we should actively improve the relevant examination and take standardized treatment as soon as possible.
