How common is numbness and tingling in stroke?

A stroke affects blood flow to part of the brain. Because different brain areas control different functions, symptoms can vary. Sensation may change in the face, arm, leg, or one side of the body. Tingling or numbness can occur with weakness, a drooping face, difficulty speaking or understanding, sudden vision changes, loss of balance, or a severe headache.

Symptoms can be brief, mild, or dramatic, but a person should not wait to see whether they disappear. Numbness and tingling also have causes other than stroke. Emergency action is based on a sudden new neurological pattern, rather than on trying to decide the cause at home.

If symptoms are happening now or started suddenly, call emergency services immediately. Note when the person was last known to be well, if you can do so without delaying the call. Keep them safe and seated or lying comfortably, and avoid giving food, drink, or medicines unless emergency professionals advise it. Do not drive yourself or the affected person to hospital if emergency transport is available.

If the symptoms have already resolved, urgent assessment is still needed. A past episode of sudden neurological symptoms should be described clearly, including the body area involved, speech or vision changes, and the order in which symptoms developed.

Seek emergency help for sudden numbness or weakness of the face, arm, or leg, especially on one side; new facial drooping; speech difficulty; confusion; sudden loss or change of vision; severe unsteadiness; or a sudden severe headache. Call even when the person seems uncertain, the symptoms improve, or there is no pain. Fast medical assessment is essential for new stroke-like symptoms.

After emergency assessment, you may ask: What was the likely cause of my symptoms? What tests or follow-up are needed? Which medicines and lifestyle measures are appropriate for me? What changes should prompt another emergency call?
