Common causes of foot numbness include the following:
1. Nerve compression: Prolonged squatting or standing, or conditions such as lumbar spine disease and sciatic nerve injury, may compress nerves and lead to foot numbness.
2. Vascular factors: Conditions such as lower limb arterial stenosis, blockage, or plaque formation that result in ischemic symptoms can also cause foot numbness.
3. Peripheral neuropathy: Conditions such as peripheral nerve inflammation or diabetic peripheral neuropathy can trigger foot numbness. Particularly in diabetic patients, long-term high blood sugar can damage peripheral nerves, causing numbness.
4. Lumbar spine disorders: Conditions such as lumbar spinal stenosis or lumbar disc herniation may compress local nerve roots, causing pain and numbness in the lower limbs.
5. Medication side effects: Certain medications, such as chemotherapy drugs and anti-tuberculosis medications, may have toxic effects on the nervous system, causing peripheral neuropathy and resulting in numbness in the hands and feet.
If experiencing foot numbness, it is recommended to seek medical attention promptly.
