Foot numbness, commonly referred to as "paresthesia," can be caused by various factors.
- Prolonged maintenance of the same posture, such as sitting with crossed legs or standing for extended periods, may lead to poor local blood circulation and nerve compression, resulting in numbness in the feet.
- Exposure to cold environments may cause malfunction of the foot nerves, resulting in a numb sensation.
- Spinal disorders such as cervical spondylosis and lumbar disc herniation may compress nerves, causing numbness in the lower limbs.
- Neurological diseases such as diabetic neuropathy and multiple sclerosis can also cause abnormal sensations in the feet, leading to numbness.
- Vitamin C deficiency or Qi and blood deficiency may also cause foot numbness. Vitamin C plays a role in hematopoiesis and iron absorption, and its deficiency may lead to insufficient Qi and blood. Individuals with Qi and blood deficiency may experience inadequate cellular nourishment, making them prone to foot numbness.
- Metabolic disorders such as thyroid dysfunction and chronic alcohol intoxication are also associated with foot numbness.
- Medication side effects, trauma, or nerve compression due to tumors may also lead to foot numbness.
If symptoms of foot numbness persist, it is important to seek evaluation at a qualified medical facility.
