The head has a needle pain may be caused by the following reasons: first, because there are cerebrovascular lesions, such as cerebrovascular malformation, cerebrovascular spasm, cerebrovascular tumor, etc., because when there are these cerebrovascular lesions, it will cause the lesion site of the blood vessel bruising or vascular blood flow is reduced, it can lead to the brain’s energy metabolism disorders, causing brain ischemia, hypoxia, so that brain nerve dysfunction, central nervous system disorders, sensory nerve excitation will have the phenomenon of head pain. The system is disrupted, and there will be sensory nerve excitement and the phenomenon of headache with pins and needles. Second, it may be due to elevated blood pressure, because when a person’s blood pressure rises, the elevated blood pressure will produce strong stimulation and dilation of the cerebral blood vessels, causing sympathetic nerves or sensory nerve excitation of the blood vessels, resulting in the abnormal sensation of headache with pins and needles.
