Weakness in the legs is a precursor to what?

Weakness of legs may be the precursor of physiological causes, cerebral infarction, lumbar disc herniation, deep varicose veins of the lower limbs and other diseases.
1. Physiological reasons: If you exercise too much or overwork, it will lead to the symptoms of leg soreness, weakness and tenderness,
2. Cerebral infarction: embolism in local brain tissues will lead to blood circulation obstruction and poor blood flow, thus causing ischemia and hypoxia in brain tissues, impairing the nerve function, and resulting in symptoms of lower limb weakness and leg tenderness.
3. Herniated lumbar intervertebral disc: degenerative changes in the lumbar intervertebral disc will compress the nerves around the lumbar intervertebral disc, causing damage to the innervated area and weakness and tenderness of the lower limbs.
4. Varicose veins of the lower limbs: when the veins of the lower limbs become obstructive, it will cause varicose veins and lead to the accumulation of a large amount of venous blood, which affects the blood circulation of the lower limbs and makes the legs soft and weak.
When there is weakness in the legs, it is necessary to pay attention to it and go to the hospital in time to make a clear diagnosis and take active treatment as early as possible.
