There are many possible causes:
Remaining in the same seated or standing position for a long time
Injury to a nerve -- for example, a neck injury may cause you to feel numbness anywhere along your arm or hand, while a low back injury can cause numbness or tingling down the back of your leg
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)
Other medical conditions, including:
Carpal tunnel syndrome
Diabetes
Migraines
Multiple sclerosis
Seizures
Stroke
Transient ischemic attack (TIA)
Underactive thyroid
Abnormal levels of calcium, potassium, or sodium in your body
A lack of vitamin B12 or other vitamin
Certain medications
Toxic action on nerves, such as that from lead, alcohol, or tobacco
