Numbness is more serious than pain. Both pain and numbness are manifestations of stimulation of sensory nerves, and both are superficial sensations, but pain is a normal response to stimulation of sensory behavior, and having pain indicates that the patient’s sensory conduction pathway is basically normal. Numbness, on the other hand, is a manifestation of hyperalgesia, indicating that there is something wrong with the patient’s sensory conduction pathway, such as cerebral infarction, transient ischemic attack, cerebral hemorrhage, spinal cord injury, spinal stenosis, and peripheral neuropathy caused by diabetes, poisoning, drugs, trauma, metabolic abnormalities, etc., which can lead to symptoms of numbness in the trunk or limbs. Therefore, numbness is a more serious sensory symptom and requires timely improvement of neurological examination for early and clear diagnosis.
