Many people worry about whether they have a stroke when they feel hand numbness.

In fact, the location of the hand numbness is different, and the reasons are different.

The nerve line in the hand extends from the tip of the finger to the arm, then to the shoulder and neck, connects to the spinal nerve, and ends in the brain.

Because these nerve lines pass through multiple body structures, any lesions or injuries, such as common cervical nerve line compression, will affect sensory conduction and induce paralysis of the relevant hand position.

Pure finger or elbow palsy mostly involves nerve line problems. The whole hand is numb or the blood supply to brain cells is insufficient, but statistically the probability of stroke is still not high.

If one side of the body is paralyzed from face to toe, then you have to consider whether you have a stroke.

Hand paralysis is more common in local areas, such as thumb, index finger and middle finger paralysis, which may be carpal tunnel syndrome.

There are two protruding flesh on the inner and outer sides of the palm, like a narrow valley in the middle, and the carpal tunnel under the narrow valley.

In the middle of the carpal tunnel, there is a very narrow place for the nerves to pass through, and there are also finger ligaments passing through.

Typing frequently or doing heavy work frequently can cause long-term strain on the ligaments of the fingers, and the swelling of the ligaments compresses the nerves, which can cause the three fingers to be paralyzed.

Long-term lowering of the head and using the mobile phone can cause elbow pain

Have you ever tried palsy on the lateral side of the elbow?

It often occurs just after waking up or working hard for a day in the office, which may involve cervical spine problems.

There are 7 cervical vertebrae, and there are intervertebral foramen between the vertebral body and the nerve thread passing through it.

Long-term use of a computer with improper posture or lowering your head with a mobile phone can often cause cervical vertebrae displacement of the fifth and sixth segments, degeneration of intervertebral discs or ligaments, compression of the sixth nerve line, and elbow pain.

If the whole hand feels numb pain and persists, one of the possibilities is a cerebrovascular problem, mainly because there is not enough blood flow to the brain cells.

The reason behind this is that the patient has risk factors such as high blood pressure, high blood fat or high blood sugar.

Patients need to take these physical warning signs seriously and seek medical advice as soon as possible to avoid more serious physical problems.

Stroke generally causes one side of body numbness and simple hand numbness, the chance of stroke is low

Is the whole hand numbness a sign of stroke?

Stroke refers to all diseases related to cerebrovascular. Stroke can produce paralysis, but most of the paralysis caused by stroke affects half of the body, such as from face to foot, or one hand and one foot. It is not common to simply cause hand paralysis.

So when it's just hand numbness, it is often not caused by a stroke.

Both hands are paralyzed together, and the chance of a stroke is also very low; because the blood vessels on both sides of the brain rarely have problems together, and at the same time it causes paralysis of the body on both sides.

In addition to causing paralysis on one side of the body, a stroke can also make you feel weak.

Therefore, when hand numbness occurs, you should seek medical attention first, and the doctor will diagnose whether it involves cerebrovascular problems or nerve compression.
