1, upper limb nerve compression:

(1) refers to numbness and pain of thumb, food and middle finger, and often has a history of waking up at night. After waking up, the activity can be improved. Severe cases may be accompanied by hand muscle atrophy, which affects fine hand movements. This is because the median nerve is compressed at the wrist, which is called carpal tunnel syndrome.

(2) It is numbness and pain in the ring finger and the little finger, and it may also have a history of waking up at night. Severe cases are accompanied by muscle atrophy, and the strength of ring finger and little finger decreases, which affects fine movements. This is because the nerve is compressed at the elbow, which is called "cubital tunnel syndrome".

2, cervical spondylosis:

The most common disease causing hand numbness is cervical spondylosis, which is one of the most common diseases in middle-aged and elderly people. In addition to finger numbness and abnormal sensation, cervical spondylosis is accompanied by other symptoms, such as neck and shoulder muscle pain, upper limb radiation pain or dyskinesia. It is not difficult to diagnose cervical spondylosis. Just take an X-ray. In addition, there is a simple method to check cervical spondylosis. One person holds the head of the affected side, one hand holds the upper limb of the affected side, abduction is 90 degrees, and both hands push and pull in the opposite direction at the same time. Those with radiation pain or numbness can be initially diagnosed as cervical spondylosis.

3 strokes:

Another common disease that causes hand numbness is stroke. Such as headache, dizziness, top-heaviness, numbness of limbs, tongue swelling and other symptoms, patients usually have hypertension, hyperlipidemia, diabetes, cerebral arteriosclerosis and other diseases. They should pay more attention to and be alert to the occurrence of stroke.

In short, the diagnosis of hand numbness symptoms needs to refer to cervical radiographs, electromyography and other auxiliary examinations to make a clear diagnosis. Once diagnosed, if the symptoms are still mild, they can be improved to varying degrees through regular non-surgical treatment. If the symptoms are obvious and there is obvious muscular atrophy in the hand, surgical treatment should be carried out in time to prevent the development of the disease, so as not to cause irreversible severe atrophy of the internal muscles of the hand and lead to serious dysfunction of the hand.
