Why does the back of the head hurt after experiencing excessive internal heat (fire-heat)?

The causes of pain in the back of the head after heatiness may involve several aspects: 1. Heatiness factors: Dry climate, spicy diet, and other factors may lead to heatiness, causing a sudden rush of blood to the cerebral vessels, which can result in vascular blockage or cerebral hypoxia, thereby causing pain. 2. Cervical spondylosis: Cervical spondylosis may cause compression of cervical nerves, leading to occipital pain, and may be accompanied by symptoms such as neck and back pain and dizziness. 3. Hypertension: Heatiness may cause elevated blood pressure, leading to insufficient cerebral blood supply and hypoxic symptoms, resulting in head pain. 4. Occipital neuralgia: Invasion by viruses may cause occipital neuralgia, characterized by paroxysmal, needle-like pain in the occipital region lasting from several seconds to dozens of seconds. In response to the above causes, it is recommended to take appropriate measures such as adjusting diet, engaging in moderate exercise, and treating cervical spondylosis, to alleviate symptoms of occipital pain. Patients with concerns are advised to seek timely medical consultation.
