Numbness in the fingers is a symptom, but as I have said more than once, “A symptom can never indicate a disease or confirm a disease!” A disease may have multiple symptoms at the same time, and numbness in the hand may well be one of these symptoms, so clinically, we can predict the possible symptoms by the disease, but it is difficult to reverse the diagnosis of a disease because of a common symptom, which is not only broader in scope, but may also mislead the patient and cause some bad results. But since the patient asked, I’ll be bold enough to make a prediction and make a preliminary judgment! 1, the most common is cervical spondylosis, the patient is likely to feel abnormal symptoms, such as numbness and soreness, at the unilateral arm and fingers. 2, the same spinal disease, but is a lumbar spine problems, patients in addition to upper limb numbness, in the lower limbs can also feel obvious discomfort, lower limb numbness, weakness, mobility is affected, the more serious patients will also hurt the kidneys, incontinence occurs. 3. If the patient is too old, brain disease can be suspected, or can be induced by cervical spine lesions, necrosis of the brain area due to ischemia, and the patient can experience unilateral limb dysfunction, that is, discomfort on half of the body, numbness, weakness, slurred speech, etc. 4, nerve problems, this may be caused by cervical spine lesions, our palm of the radial nerve, ulnar nerve, median nerve are reached through the cervical spine, how the patient cervical spine problems or recent mood swings too much, will probably make nerve disorders occur hand numbness symptoms, the difference lies in the length of time. Comprehensive above possible common degree, the most suspicious is still cervical spine lesions! It was about the 19th of last month, when I went out to the clinic, I met a 49-year-old woman who had hand numbness for nearly 2 months, with soreness and weakness in her arm, and her symptoms were mainly in her right hand. After my observation, I found that her middle finger had a higher degree of numbness, and the adjacent ring finger and little finger also had abnormalities, but the symptoms were mild. I guessed that the lesion was in the C6-7 segment, although T1 was also possible, but the patient was financially poor and was not willing to undergo too many tests, so he was allowed to undergo a cervical MRI, and the final diagnosis: cervical degenerative lesion and cervical 6/7 disc herniation. This patient should have overlooked some key information. Even if the fingers are numb, it is better to describe in detail which fingers. If numbness exists in all five fingers, then the patient may have lesions in C5/6, C6/7, C7/T1, etc.
