Fans who follow me regularly may notice that I often ask patients in my clinic if they have numbness in their fingers and have them grasp their fingers quickly, what is the cause? The cause of numbness in the fingers first depends on whether it is in the whole hand or part of the fingers. For the numbness, also depends on whether it appears suddenly or gradually, according to the site and characteristics of numbness to do the appropriate examination. 1, local numbness of the fingers to consider whether it is related to the cervical spine, you can take a film to check whether there are cervical spine problems, whether there is cervical spondylosis; 2, if the numbness of the whole finger, or including the entire upper and lower limbs of numbness, consider whether the patient is an acute cerebrovascular disease, especially if it occurs suddenly, should do a cranial CT or nuclear magnetic examination for cranial infarction vascular lesions; 3, simple numbness of the tips of the five fingers to consider is peripheral nerve problem. For different causes, such as peripheral nerve, cervical spine or cerebrovascular disease, the treatment means and prognosis vary.
