Doctor's answer (1)
Dr. Chen Jian
Experiencing numbness in the left leg during rest or nighttime sleep may be related to the following factors:
1. Improper posture: Maintaining the same posture for a prolonged period, such as excessive knee flexion while sleeping on one side, may compress nerves or blood vessels, leading to poor leg circulation and causing numbness.
2. Environmental factors: If the surrounding environment is cold during rest or sleep, prolonged exposure to cold in the left leg may also cause localized numbness.
3. Diabetes: High blood sugar levels can damage the nervous system, especially the peripheral nerves, leading to symptoms such as numbness and tingling in the limbs.
4. Circulation problems: Circulatory disorders such as atherosclerosis or blood clots may also cause leg numbness.
5. Nutritional deficiencies: Nutritional deficiencies such as vitamin B12 deficiency or hypokalemia may cause abnormal nerve function, manifesting as limb numbness.
