Famous movie star S was once plagued by “radial neuritis”. This inexplicable disease made her a “one-armed” warrior for a while, unable to move her right arm, and could only develop the potential of her left hand, which made people sigh in relief and wonder what exactly is radial neuritis? Nerve damage to the arm, elbow and wrist is still quite common. Patients will have hand numbness, pain, inflexibility and other performance, numbness, pain, inflexible activities do not care should be consulted as soon as possible, if the treatment is late will be more difficult to recover. A nerve injury causes not only inflammation Nerve injury has external and internal causes. Like the inflammation of the radial nerve in the arm of Big S, it may be related to a viral infection or due to autoimmune deficiency and susceptibility to disease. Even the common cold can sometimes be a causative factor. In addition to inflammation, causes of radial nerve damage include lead poisoning, alcoholism, axillary or upper extremity pressure, and fracture of the middle humerus; in addition, radial fracture or dislocation, upper extremity penetrating injuries are also more common, and it is not uncommon to see radial nerve damage caused by pressure from poor sleeping position and pressure on the anterior oblique muscle during sleep. Second, chronic nerve strain more need to pay attention to nerve injury is more often seen in chronic nerve strain, and often not easy to find. Chronic nerve injuries related to the hand are mostly seen in the elbow and wrist. Local hyperplasia after chronic strain, deformed healing after fracture, congenital structural abnormalities or local long swelling may lead to narrowing of nerve pathways, and when the joint is active, the compressed nerve is constantly rubbing against the surrounding structures, making it easier for local edema and thickening to occur, further aggravating the nerve compression. Some people sleep with their arms pressed after getting drunk, and they may wake up with arms that can’t move. In addition, diabetic patients and women who are in labor are also at high risk for nerve entrapment. Three, hand numbness, pain, inflexibility need to be alert to nerve damage will have numbness, pain, inflexibility and other performance. Once you notice such symptoms, you should immediately go to the relevant specialist in a regular hospital for early treatment. It’s a good idea to be afraid of not paying attention at first, as some people feel numb after playing computer or mahjong for a long time, and then shake their hands to get some relief, which delays the treatment and makes it difficult to recover from muscle atrophy. Nerve problems are often slow to recover, and some are even difficult to recover and irreversible, so early detection and treatment should be emphasized. It is important to understand the cause of the disease, although all have the same symptoms, the cause may not be the same. Some nerve injuries require surgery, some require medication, and some require some simple rehabilitation. Only when you find the right cause, you won’t delay the disease. Prevention points: prevention of colds, pay attention to the combination of work and rest, work to avoid a long time fixed a posture or repeat a movement, do not press the arm to sleep, especially after drunkenness. Treatment reminder: The first task of treating nerve injury is to control the condition in time not to aggravate, on this basis and then gradually let the nerve function recovery, which is a relatively long process, the patient should have patience.
