Numbness

Numbness and tingling are abnormal sensations that can occur anywhere in your body, but are often felt in your hands, feet, arms, or legs.

There are many possible causes:

  • Remaining in the same seated or standing position for a long time.
  • Injuring a nerve supplying the body part where you feel the sensation. If you have a neck injury, for example, you may feel the sensation anywhere along your arm or hand.
  • Similarly, a low back injury can cause sciatica — a sensation of numbness or tingling down the back of your leg.
  • Lack of blood supply to the area. For example, plaque buildup from atherosclerosis in the legs can cause pain, numbness, and tingling while walking. (This is called claudication.)
  • Pressure on the spinal nerves, like that from a herniated disk.
  • Carpal tunnel syndrome. This can cause numbness or tingling in your wrist, fingers, hand, or forearm.
  • Certain medical conditions, including diabetes, under active thyroid, multiple sclerosis, seizures, or migraine headaches.
  • Abnormal levels of calcium, potassium, or sodium in your body.
  • Vitamin B12 deficiency.
  • Transient ischemic attack (TIA) or stroke
  • Certain medications.
  • Toxic action on nerves, such as that from lead, alcohol, or tobacco.
  • Radiation therapy.

 

Complications:

  • Decrease in feeling
  • Prone to accidental injury
