Do not wait to see whether they disappear.
A transient ischemic attack, sometimes called a mini-stroke, can produce temporary neurological symptoms that resolve on their own but still requires urgent evaluation because it may signal an increased risk of a future stroke.
20. Numbness With Chest Pain Is Also Concerning
Hand or arm numbness accompanied by chest discomfort deserves immediate attention.
This is particularly important if the symptoms include:
-
Pressure or squeezing in the chest
-
Shortness of breath
-
Sweating
-
Nausea
-
Dizziness
-
Pain spreading into the jaw, shoulder, back, or arm
Heart-related symptoms don't always follow a textbook pattern.
They can vary from person to person.
If you experience sudden unexplained chest symptoms with arm or hand sensations, don't assume you simply slept on your arm.
Seek urgent medical attention.
How Doctors Evaluate Persistent Hand Numbness
If numbness keeps coming back, a healthcare professional will usually begin by asking detailed questions.
They may want to know:
-
When did it begin?
-
Is it one hand or both?
-
Which fingers are affected?
-
Is it worse at night?
-
Does movement change it?
-
Is there neck pain?
-
Is there weakness?
-
Have you experienced an injury?
-
What medications do you take?
-
Do you have diabetes or another chronic condition?
A physical examination may assess:
-
Muscle strength
-
Reflexes
-
Sensation
-
Coordination
-
Grip
-
Nerve function
-
Neck and wrist movement
Depending on the suspected cause, additional testing might include blood tests, nerve conduction studies, electromyography, or imaging.
The goal is to identify where the nerve problem is occurring and why.
What Can You Do at Home for Mild, Occasional Numbness?
If your hand occasionally becomes numb because you slept on it or kept your wrist in an awkward position, simple changes may help.
Change your sleeping position
Avoid placing your arm underneath your body.
Keep your wrist relatively neutral
Try not to sleep with the wrist tightly bent.
Take breaks during repetitive work
If you type or use a mouse for long periods, get up and move regularly.
