Hello doctor: I am 32 years old and have always been healthy, but lately, for some reason, I sometimes wake up and find that my hands are numb, and the symptoms only slowly disappear when I get out of bed and move around. What’s wrong with me? Could it be a stroke? What kind of tests should I have? What do I need to pay attention to in my daily life? Hello, there are many clinical causes of hand numbness, including intracranial factors, peripheral factors (such as cervical spondylosis), systemic factors (such as complications of diabetes, peripheral neuritis), etc. The most common is hand numbness caused by cervical spondylosis, mainly manifested as numbness or radiating pain from the fingers to the arm on one or both sides, and can be accompanied by dizziness, neck and shoulder pain. For older patients with risk factors such as hypertension, diabetes, hyperlipidemia, etc., a sudden onset of hemianesthesia of the hands and feet with symptoms of transient weakness of the limbs may be a precursor of stroke. Since you are still young and in good health, it is suspected that you may be suffering from cervical spondylosis (nerve root type). This cause should be considered if there is unexplained numbness in the upper extremities, especially if fingertip paresthesia is evident. These diseases are related to changes in body position and are often triggered by exertion, cold and poor sleeping posture at night. People who are engaged in light work, such as those who face the computer for a long time, those who read and write for a long time and drivers, are also more likely to suffer from this kind of disease. Cervical spondylosis is caused by degenerative degeneration of the cervical disc and cervical spine osteophytes, which stimulates or compresses the adjacent spinal cord, nerve roots, blood vessels and sympathetic nerves, resulting in a series of performance of the neck, shoulders and upper limbs. Long-term ambulatory work may cause hand numbness due to cervical spine osteophytes, intervertebral disc degeneration or local joint ligament lesions that compress the local blood vessels and nerve tissues in the cervical spine. You can check fasting blood sugar, perform X-ray examination of the cervical spine, CT of the neck, MR examination of the neck, etc. There are also clinical examinations such as pull test and intervertebral foraminal squeeze test, etc. Patients with cervical spondylosis often present positive signs. It is recommended that you go to a regular hospital to receive standardized treatment after diagnosis, and wish to eliminate the symptoms of hand numbness as soon as possible.
