Xiao Liu works in an office building, due to the need to work, often arm support on the table, with hands on the cheek to stare at the computer screen for half a day, but also like to sleep on the arm. Six months ago he suddenly began to appear numbness in his left hand, mainly the little finger, the degree is not heavy, so did not pay much attention. Later, the numbness became more and more severe and extended to the ring finger and palm area. Recently he suddenly found that his left hand strength decreased significantly, the left hand than the right hand “thin” a lot, so went to the hospital to check. After doing an electromyogram, the doctor told him that it was “elbow canal syndrome” and that there was already a manifestation of left hand paralysis, which needed to be treated with surgery as soon as possible, otherwise the damaged muscle strength and sensation might not be restored. I never thought that a seemingly simple hand numbness could have such serious consequences. So, what is elbow-tube syndrome? Elbow canal syndrome is a disorder caused by ulnar nerve compression due to traumatic arthritis of the elbow, with a thickened fibrous band between the two heads of the ulnar carpal flexors, which compresses the ulnar nerve. In the early stage of symptoms, patients often feel numbness and discomfort in the little finger. Sometimes they have difficulty in writing and using chopsticks. When the symptoms are aggravated, the ulnar carpal flexors and ring finger and pinky finger deep flexors are weak, the intrinsic hand muscles atrophy, and mild claw finger deformity appears. So once the symptoms of hand numbness, do not take it lightly, it may be a precursor to paralysis. We often encounter the phenomenon of hand numbness in our lives, such as sleeping on the pillow arm will appear hand numbness, but some people, especially some middle-aged and elderly people encounter the phenomenon of hand numbness must be vigilant. In the end, hand numbness is what is going on, is the local circulation of Qi and blood is not good or the harbinger of certain diseases, must not be underestimated, here we will look at hand numbness and may suggest what diseases. Hand numbness may also suggest these physical diseases 1, cervical spine problems: clinically, most of the nerve compression that leads to hand numbness occurs in the neck, the proportion of at least seventy percent, sometimes even up to 90%. Most of these people are accompanied by symptoms such as cervical joint hyperplasia or ligament calcification, and in serious cases, also accompanied by joint movement restrictions in both upper limbs. The lifestyle habits of these patients are invariably sedentary, always maintaining a posture of immobility. In addition to numbness of the fingers, cervical spondylosis is accompanied by symptoms such as muscle pain in the neck and shoulder and radiating pain in the upper limbs. Therefore, when there is unilateral hand numbness symptoms, it is recommended to exclude neuropathy, and then alert whether it is cervical spondylosis. 2, menopause: menopause will also have certain symptoms of hand numbness, this stage of hormone level changes, organ function is affected, may lead to blood pressure fluctuations, mood irritability, etc., hand numbness is only one of the symptoms, generally after the hormone level is stable, the corresponding symptoms will ease on their own. 3, stroke: all nerves are derived from the brain, when the brain out of order. Such as a stroke, the area governed by the brain will appear numbness, weakness. The appearance of hand numbness in the elderly may also be a manifestation of stroke, and may be due to spinal cord disease, diabetes and other diseases, the cause is complex and may be very harmful. Therefore, it is necessary to find a specialist in time to identify the cause and do targeted treatment. 4, high blood lipid: long-term high blood lipid, easy to cause hardening of the blood vessel wall, coupled with high blood lipid, blood viscosity, blood flow becomes slower, the cells get less oxygen nutrients, resulting in numbness. 5, diabetes: blood sugar to maintain a high level, a long time, the human blood vessels, nerves caused great damage, vascular sclerosis, nerve degeneration. Frequent hand numbness recommended to seek medical attention Once the arm or finger often numb, it means that the nerve has been insensitive to pressure, the situation is more serious. Hand numbness belongs to a chronic strain disease, if late treatment will affect the future life of the elderly, and easy to recur. Therefore, when the numbness of the arm or finger is frequent, you should immediately go to the hospital to identify the cause and timely treatment. In general, an X-ray can determine whether there is any organic lesion in the cervical spine, whether there is ligament calcification or osteophytes, and if so, the next systematic treatment can be done. After a series of treatment, usually will recover.
