• Pressure on the spinal nerves such as that due to a herniated disk
• Lack of blood supply to an area -- for example, plaque buildup from atherosclerosis in the legs can cause pain, numbness, and tingling while walking (this is called vascular claudication)

  • Carpal tunnel syndrome
  • Diabetes
  • Migraines
  • Multiple sclerosis
  • Seizures
