In life, have you ever experienced numbness in your fingers, sometimes after a long time of tapping the keyboard, this numbness of the hand suddenly appears, like ants crawling under the skin, forcing you to put down the task at hand, began to relax the fingers, and after a while, this numbness disappeared.
In fact, this situation is clinically known as "physiological hand anesthesia", and there are two main reasons for its occurrence, the first is excessive hand activity. The second is to maintain a posture for a long time, compressing the blood circulation or nervous system of the hand, resulting in poor blood circulation, followed by numbness in the fingers, which can be relieved after proper activity.
However, if you have recently experienced repeated symptoms of finger numbness, this may not be a physiological hand numbness, but the disease has found its own manifestations. According to the current clinical data, the following diseases will cause numbness in the fingers:
1. Carpal tunnel syndrome
The disease is also clinically known as late-onset symptoms of nerve palsy, especially in people who work on computers for a long time.
It mainly refers to a series of symptoms that occur after the median nerve in the human body enters the meridians of the palm of the hand, which is the most common symptom is that the patient's palm surface and fingers are abnormally numb and painful, and may also be accompanied by symptoms such as inflexibility and weakness of hand movements.
This numbness and pain, often aggravated at night or early in the morning, and even radiates to the patient's elbows and shoulders, and the numbness is reduced after daytime activities and forceful hand throwing, but it will recur, if not treated in time, it will even cause hand muscle atrophy and paralysis;
2. Stroke
The so-called stroke refers to acute cerebrovascular disease, which is divided into two categories: ischemic and hemorrhagic, ischemic stroke is commonly known as cerebral infarction. After cerebral infarction, the blood supply to brain tissue is blocked, and some brain tissue can be softened or necrotic due to ischemia.
If the cerebral infarction spreads to the motor center, in the early stage of cerebral infarction, the patient will have abnormal limb symptoms, such as numbness and weakness in one limb, and the inability of the arm to be lifted normally. If the cerebral infarction is sudden and the symptoms are serious, the patient will even suddenly hemiplegia and walking hard, which is also one of the most common sequelae of stroke;
3. Cervical spondylosis
Many people's cognition of cervical spondylosis is stuck in the neck and shoulder pain, neck movement disorders and other aspects. As everyone knows, the symptoms of cervical spondylosis are quite complex, to know that the sensory nerves in the finger area are actually the nerve roots separated from the cervical spinal cord, which are distributed to the hands and fingers through the upper arm and forearm.
If there is a lesion in the cervical spine, especially the cervical vertebral shoulder disc herniation, or the cervical spine has hypertrophic joints, it will cause compression on the surrounding cervical nerve roots, and its symptoms can radiate to the hand with the nerves, resulting in symptoms such as numbness and weakness of the fingers.
All in all, the occasional hand numbness is basically physiological, which is the body reminding you that it is time to put down the work at hand and get up and move.
However, if there are frequent symptoms of hand anesthesia recently, especially if hand anesthesia has affected normal life, or if hand anesthesia is accompanied by other symptoms, this may be a signal of the arrival of the disease, and patients should be vigilant and actively seek medical treatment for relevant examinations.
