Purely from the clinical symptoms described, it is generally common that it is caused by insufficient blood supply to the brain. This symptom is especially aggravated when the head is lowered for a long time, or when the head is rotated or stimulated by cold, which is basically a common vertebral artery cervical spondylosis, so you should go to a hospital to see an orthopedic surgeon or a spine surgeon. Because of the corresponding lesions in the cervical spine, the symptoms described now will occur after the vertebral artery is irritated and strained and the blood supply is insufficient, causing a lack of blood supply to the brain. The common causes are playing with the cell phone with the head down, working at a desk, sitting and driving for a long time, and if necessary, the diagnosis of the disease can be clarified by a cervical spine photograph or CT or even MRI examination. Normally, attention should be paid to avoid the habit of prolonged head bowing, and then, according to the examination results, symptomatic treatments such as acupuncture or small acupuncture can be considered.
