What causes foot numbness and how is it treated?

Foot numbness may be caused by various factors:

1. Prolonged sitting or standing: In this situation, blood circulation in the lower limbs is impaired, leading to capillary expansion and subsequent numbness in the feet. This condition typically resolves on its own after resuming limb movement.

2. Disease-related factors:

Arthritis: Chronic inflammation of the ankle joint caused by degenerative changes, chronic strain, or other factors may lead to symptoms such as foot numbness and pain.

Peripheral neuropathy: Infections, nutritional and metabolic factors, or other causes may damage peripheral nerves, resulting in limb numbness, foot drop, and related symptoms.

Cervical spondylosis and lumbar disc herniation: These conditions may compress nerve tissues, causing foot numbness and restricted lower limb movement.

Other diseases: Conditions such as diabetes, rheumatism, and stroke may also cause foot numbness.

Treatment for foot numbness should be based on the specific cause:

1. Physical therapy: Massage, heat application, and moderate exercise can promote blood circulation and alleviate symptoms of foot numbness.

2. Medication: Depending on the underlying cause, doctors may prescribe appropriate medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or nerve-nourishing medications.

3. Surgical treatment: Severe foot numbness caused by conditions like cervical spondylosis or lumbar disc herniation may require surgery to relieve nerve compression.

In addition, maintaining healthy lifestyle habits is important for disease prevention.
