What causes numbness in the feet, and how can it be resolved?

Possible causes of numbness in the feet include: 1. Vascular factors: conditions such as atherosclerosis or varicose veins that impair blood circulation in the feet. 2. Neurological factors: nerve compression due to lumbar disc herniation, sciatica, or similar conditions. 3. Metabolic factors: metabolic disorders such as diabetes or hypothyroidism. 4. Mechanical factors: prolonged maintenance of the same posture or external pressure on the feet. Methods to relieve foot numbness: 1. Engage in appropriate exercise to improve blood circulation and alleviate symptoms. 2. Keep feet warm to prevent numbness caused by cold exposure. 3. Treat underlying medical conditions, such as supplementing vitamin B, controlling blood sugar levels, or managing cervical or lumbar spine diseases. 4. Try simple techniques like shaking the legs, raising the arms, or massage, which may also help reduce foot numbness.
