The causes of numbness of legs and feet may be related to physiological factors, or may be caused by cervical spondylosis, lumbar spondylosis, cerebrovascular disease and other reasons.
1. Physiological factors: for example, stilts legs for a long time, or sleeping with the lower limbs under pressure for a long time, etc., may lead to poor blood circulation in the lower limbs, which may cause numbness in the legs and feet.
2. Cervical spondylosis: commonly found in vertebral artery type cervical spondylosis, which can easily lead to localized nerve root compression, which may cause numbness in the legs and feet, and may also be accompanied by neck pain, stiffness and other manifestations.
3. Lumbar spine lesions: commonly found in lumbar disc herniation, lumbar spinal stenosis, etc., which can easily lead to local nerve root compression, resulting in sensory impairment in the area innervated by the compressed nerves, which may cause numbness of legs and feet.
4. Cerebrovascular diseases: for example, cerebral infarction, transient ischemic attack, etc., due to local ischemia of brain tissue, resulting in cerebral nerve damage, brain dysfunction, may cause numbness of legs and feet.
Numbness of legs and feet, exclude physiological factors, should seek medical treatment as soon as possible, after the cause is clear, give targeted treatment.
