The main reason for scalp numbness is the lack of blood supply to the scalp of the brain, which is inseparable from work and rest, as well as the posture at work. It may also be caused by cervical spondylosis or vertebral artery stenosis, or the effect of a pillow that is too hard and too high. It is recommended to do a cervical spine MRI or CT examination to confirm the diagnosis before treatment. Pay attention to rest and avoid staying up late. Before going to bed at night, comb your head with a comb, it is best to comb a few more times to keep the blood supply to your scalp replenished while you sleep, which will not only cure your scalp tingling, but also keep your brain awake.
