Get StartedWhen to see a doctor
By Mayo Clinic staffIt's important to determine the cause of numbness in hands. If numbness persists or spreads to other parts of your body, consult your doctor for an evaluation. Treatment of numbness in hands depends on the underlying cause.
Call 911 or get emergency medical help if your numbness:
- Begins suddenly
- Involves a whole arm
- Is accompanied by weakness or paralysis, confusion, difficulty talking, dizziness, or a sudden, severe headache
Schedule an office visit if your numbness:
- Begins or worsens gradually and persists
- Spreads to other parts of the body
- Affects both sides of the body
- Comes and goes
- Seems related to certain tasks or activities, particularly repetitive motions
- Affects only a part of a limb, such as a finger
