Numbness is caused by damage, irritation or compression of nerves. A single nerve branch or several nerves may be affected, as with a slipped disk in the back or carpal tunnel syndrome in the wrist.
Numbness and tingling can be caused by other medical conditions, including:
- Carpal tunnel syndrome (pressure on a nerve at the wrist)
- Diabetes.
- Migraines.
- Multiple sclerosis.
- Seizures.
- Stroke.
- Transient ischemic attack (TIA), sometimes called a "mini-stroke"
