Doctors at the German University Hospital Dresden reported that the feeling of tingling in the fingertips at night indicates the infection with what is known as carpal tunnel syndrome, which occurs due to the presence of pressure on the nerves in the carpal tunnel in the hand. They explained that this pressure is often caused by severe hand stress at work or exposure to strokes, in addition to obesity, and that often affects the thumb, forefinger and middle. This pressure causes the carpal tunnel not to supply blood and narrows it, which leads to the death of nerve cells, and then the hand loses its motor skills, as the patient, for example, cannot open the door, and objects fall out of his hand easily due to numbness. To avoid this, carpal tunnel syndrome should be treated in a timely manner, with a special splint at first. In the event that the tingling, numbness and manifestations of paralysis persist despite conservative treatment methods, then the hand may be required to undergo surgery.
