Physiological numbness in the hands and feet usually occurs after being compressed and maintaining a fixed posture continuously, for example, when pressing the arm during sleep, or carrying a heavy object for a long time, resulting in insufficient blood supply to the peripheral blood vessels, causing numbness. In this case, the symptoms are mild, and after rest, massage, and relaxation, the symptoms will ease or disappear. Pathological numbness, recurrent, persistent exacerbation, may be accompanied by other symptoms, behind the hidden disease signals, need to be carefully identified, can be from 10 angles, to find the common real cause.

The countermeasure to control this numbness is to control the blood glucose index within the range of the standard. The second type of cause is cervical spine or lumbar spine disease, due to nerve root compression, causing sensory abnormalities and pain in the corresponding nerve distribution area, this type of numbness may be related to changes in body position, for example, patients with radiculocarpactal cervical spondylosis, when sitting, begin to feel hand numbness, move the cervical spine, for example, when the neck is flexed or extended, the symptoms have improved.

The fourth type of cause is peripheral neuritis, which causes vitamin B1 deficiency due to long-term malnutrition, causing tingling in the hands and feet. The fifth type of cause, hyperuricemia, due to uric acid deposition, compresses the nerves, causes numbness or pain, and is characterized by constant changes in the part where numbness occurs. The sixth type of cause, arteriosclerosis, causes transient cerebral ischemia, leading to numbness in the limb, characterized by numbness in the upper or lower extremities on one side, lasting from a few hours to several days.
