"After waking up, the whole arm was numb, as if countless ants had crawled past."
Under normal circumstances, this numbness can quickly recover.However, if hand numbness often occurs for no reason, it is repeated, at this time, you need to be alert to the possibility of disease.
"Life Times" interviewed experts tells you the truth behind the symptoms of "getting numb".

Going to the toilet or sleeping occasionally, you don’t have to worry too much.
This is a physiological numbness caused by poor peripheral blood circulation, insufficient local blood supply, or nerve compression of external force.
However, if the intermittent numbness of the fingers appears for a long time or no obvious causes, and even suddenly wakes up due to numb pain at night, you must be vigilant. It may be that 7 "diseases" are looking for you.
Unilateral hands appear
When the symptoms of unilateral numbness appear, we can conduct preliminary self -assessment and find the cause.
1 nerve root cervical spondylosis
If you are in a sitting position, your hand starts to numb and change the position of the head (cervical spine).Essence
In clinical, nearly 70 % of the symptoms of numbness are caused by nerve root cervical spondylosis.
Due to the degeneration of the cervical disc, secondary pathological changes, the nerve root is compressed, and pain in the corresponding nerve distribution area is caused.Generally speaking: thumb numbness indicates the sixth neck nerve root.The index finger, middle finger, and ring finger indicate that the seventh neck nerve root is compressed.The little finger indicates that the eighth neck nerve is compressed.
In addition, the patient’s neck and shoulders are often sore in muscle, and severe symptoms such as vomiting, dizziness, and tinnitus.
2 Carpal Tunomon Syndrome
If the wrist is maintained at the maximum flexion position, the thumb, index finger, and middle finger of thumbs, index finger, and middle finger within 60 seconds, consider it as a vessel syndrome.
Excessive use of fingers, especially repetitive activities, such as mouse or typing for a long time, can cause vestoing syndrome.
Its main manifestations are numbness of thumbs, index finger, and middle fingers. There are often history of wake -up at night, and the activity after waking up can improve.In severe cases, it may be accompanied by symptoms of hand muscle atrophy, affecting fine movements of the hand.
3 Short -term cerebral ischemia/stroke
Cerebral arteriosclerosis or stenosis, thrombosis, insufficient blood supply, etc. may induce short -term cerebral ischemia, and may indicate high -risk diseases such as cerebral infarction in severe cases.
Often manifested as fingers or on one limb to numb.If you have symptoms such as headache and dizziness, dark vision or blurred sight, nonsense, poor coordination ability, etc., it may be a sign of stroke.
If these symptoms often occur, you should seek medical treatment in time.
Bilateral symmetrical hand anesthesia
If bilateral symmetrical hand numbness occurs, the following diseases need to be detected.
Bilateral finger numbness is a common symptom of the surrounding neuropathy of diabetes. It is often symmetrical when onset, similar to the feeling of wearing gloves or wearing socks.
Many diabetic patients have not been effectively controlled, and a variety of complications have appeared in the early days. Therefore, even if patients have no history of diabetes, those with long -term numbness should also do diabetes screening.
If people who often have numbness in alcoholism, they may be poisoned by chronic alcohol. If they are not intervened in time, they can cause dysfunction of various systems of the body and even irreversible damage.
3 Diet or medication habits
Picky eaters lead to the deficiency of vitamin B, which can also cause peripheral neuropathy, leading to numbness; often using some diarrhea and anti -infective drugs, the same problems will occur.
At this time, as long as you have a reasonable diet, stop the medicine or change the medicine.
4 Late pregnancy/menopause syndrome
Some pregnant women will feel the unilateral or bilateral handicapped pain, numbness, numbness, or burning.
Pain and numbness mainly affect the side of the thumb, index finger, middle finger, and small finger, which causes loss of fine movements in the fingers, and usually has no serious consequences.
Menopausal women sometimes have hand numbness symptoms, but with the end of menopause, hand numbness will disappear.
Many people think that only cervical disease can cause numbness of the arms. In fact, a considerable part of the patients with cardiovascular and cerebrovascular diseases may also appear numb.
The consequences of cardiovascular and cerebrovascular diseases are often serious, and they must be alert to numbness.
The numbness caused by cardiovascular and cerebrovascular disease usually has the following characteristics:
NO.1 numbness occurs suddenly
The occurrence of numbness may not have any signs, which can be generated in a static state, or it may occur during exercise or angry. There are also some suddenly occurred at night. Most of them do not need to be treated, and they will recover themselves.
NO.2 is widely numb, often on one side
If the infarction stove is small and only damage the nerve tissue that manages the sensory function, it will cause numbness or half -body numbness in a part of the opposite body.
If it is insufficient blood supply to the brain, it will only cause paroxysmal numbness.
With the further expansion of ischemic brain tissue, the degree of degeneration arterial occlusion will also increase. The numbness of the opposite body and facial numbness can be expanded from the part to the half body, and the transient numbness is evolved to persistent numbness.
NO.3 Symptoms have nothing to do with posture posture
Some cervical spondylosis and lumbar spondylosis can also make people feel numb, but this numbness is caused by compression of the nerves. Sometimes the body position changes, the compression is lifted, and numbness can be temporarily relieved or disappeared.
Cerebral vascular disease numbness has nothing to do with the change in position and will not disappear because of the change.
NO.4 is often accompanied by other symptoms
In addition to numbness of hands and feet, most patients with cerebrovascular disease are accompanied by weak limbs, dizziness, headache, visual impairment (blurred vision or restoration, etc.), loss of memory (especially recent memory decline), and increased blood pressure or lower blood pressure or lower phenomenon.Essence
Suddenly dizziness, vomiting, tinnitus, and unstable standing are also a precursor to cerebrovascular disease.
Hypertension can sometimes cause short cerebral ischemia or even cerebral hemorrhage, causing crooked mouth and eyes, paralysis, vague words, dislocation and coma, etc., and even cause death.
Elderly people over the age of 60 are prone to cardiovascular and cerebrovascular sclerosis. Once symptoms of hemps repeatedly, they should go to the hospital for examination in time.
