Leg numbness and leg pain are mainly related to lumbar degenerative diseases, lumbar spinal canal occupational diseases, pyriformis syndrome, and sclerotic occlusion or embolism of the arteries of the lower limbs.
1. Lumbar degenerative diseases: such as lumbar intervertebral disc herniation, lumbar spondylolisthesis, vertebral bone degeneration, etc. These diseases can lead to nerve root compression, resulting in leg pain, numbness, weakness and other symptoms.
2. Lumbar spinal canal occupational disease: such as spinal canal infection, tumor compression and lumbar spinal tuberculosis and other diseases, which can also lead to some nerve root compression in the lumbar spine, resulting in pain, numbness and weakness of the lower limbs.
3. Piriformis syndrome: it is a kind of peripheral nerve compression disease, mainly the sciatic nerve is compressed in the region of the pear-shaped muscle course, and sciatica occurs, which is manifested as buttock pain, reflex pain in the lower limbs, and lower limb skin sensory disorder.
4. Lower limb arteriosclerosis occlusion or embolism: when the lower limbs appear vascular sclerosis or thromboembolism, the affected limbs can appear pain, abnormal sensation, numbness, distal limb cold and other symptoms.
In addition to the above reasons, there are other causes of leg numbness and leg pain, such as late complications of diabetes and varicose veins, if the patient’s prolonged lower limb pain and numbness should be promptly to the hospital for examination.
