What causes numbness in the calf and feet?

Leg and foot numbness may be a normal physiological response, or it could result from medical conditions such as lumbar disc herniation or spinal stenosis. If symptoms are significant, it is recommended to seek timely medical evaluation. Under a doctor's guidance, treatment options including medication or lifestyle management can be tailored to the individual patient.

1. Normal physiological response: Prolonged exercise or incorrect exercise posture may compress the legs, leading to numbness in the calves and feet. This condition usually resolves on its own with rest and does not require specific treatment.

2. Lumbar disc herniation: Conditions such as poor long-term posture or degenerative changes in the lumbar spine may lead to lumbar disc herniation. Common clinical symptoms include lower back pain, weakness or soreness in the waist and knees, and numbness in the legs and feet. Severe cases may cause limited mobility and difficulty walking. Treatment should be guided by a physician and may include medications such as vitamin B12 tablets or Yaotongning capsules. Patients should avoid excessive fatigue in daily life and ensure adequate rest and sleep.

3. Spinal stenosis: Spinal stenosis caused by congenital abnormalities or trauma may compress the spinal cord and nerves, resulting in symptoms such as lower back aching, numbness in the lower limbs, difficulty walking, and sciatica. Treatment may involve medications such as ibuprofen sustained-release capsules or eperisone hydrochloride tablets, under medical supervision. Additionally, patients should focus on strengthening rehabilitation exercises for the neck and lower back.
