2. Migraine: When migraine attacks, it can lead to paroxysmal, throbbing pain on one side of the head or both sides of the patient, and a feeling of aura may appear in the early stage of the onset of the disease, which may cause numbness on one side of the head, and may be accompanied by nausea, vomiting and other symptoms.
3. Cervical spondylosis: especially in patients with cervical disc herniation, it is easy to lead to local vascular compression, resulting in the vertebral basilar artery does not get enough blood and oxygen supply, which may cause numbness of half of the head, and may be accompanied by dizziness, neck pain and other symptoms.
