Patients are advised to improve their environment and bad habits to keep their mood relaxed so as to avoid head discomfort. In addition, head discomfort is also common in cranial diseases, extracranial lesions, nasal diseases, neck diseases, systemic diseases and other pathological factors. I. Cranio-cerebral diseases: for example, meningitis, encephalitis, brain abscess, brain hemorrhage, subarachnoid hemorrhage, cerebral infarction, brain tumor, concussion, brain contusion, subdural hematoma, etc., can lead to head discomfort. The diagnosis can be clarified by CT and MRI of the head, and cause-specific treatment can be given according to the cause. For example, patients with massive cerebral hemorrhage can be treated with borehole drainage or craniotomy for hematoma removal. Extracranial lesions: such as skull base depression, skull tumor, trigeminal neuralgia, etc., can cause different degrees of head discomfort. Third, nasal diseases: such as chronic rhinitis, sinusitis, due to long-term nasal ventilation, resulting in lack of oxygen in the body, patients will experience dizziness, headache and other symptoms of head discomfort.

V. Systemic diseases: 1. Hypertension: When blood pressure is elevated, cerebral blood vessels are in a diffuse dilated state, so patients can have uncomfortable head performance.

If the blood pressure is elevated, oral antihypertensive drugs should be taken for treatment; 2. Hypotension: Patients’ blood pressure is lower than normal, resulting in ischemia of the brain, heart, kidneys and other important organs. Patients may experience dizziness, accompanied by black eyes, weakness of the limbs, palpitations, oliguria and other manifestations, and in severe cases, syncope or shock; 3. Anemia: Because the blood Oxygen-carrying capacity decreases, resulting in cerebral ischemia and hypoxia, patients may experience dizziness, headache, insomnia, lack of concentration and other typical symptoms include pale skin mucous membranes, shortness of breath, dyspnea, etc.; 4, other: influenza, pneumonia, upper respiratory tract infection, heart failure, hypoglycemia, heat stroke and other diseases can lead to head discomfort, it is recommended that patients go to the hospital in time to find the The cause and symptomatic treatment.
