Headache is often thought of as a minor disease, but in fact, headache is inextricably linked to many diseases, and it is not difficult to find the root cause of the disease as long as we can sort it out. Mr. Li, who suffered from headache, said that he almost delayed the treatment of glaucoma and nearly lost his eyesight because he neglected to identify the cause of headache and blindly took painkillers because of neuralgia. Who knew that the disease of the eye was manifested as a headache? Headache is not only a disease of the head, but also has complex causes, including intracranial and extracranial ones, localized headache and systemic headache, and many headaches for which the cause cannot be found so far. Many headaches are caused by inflammation, ischemia, hypoxia, necrosis, hemorrhage, and proliferation of cancerous brain tissue structures. Viral encephalitis, bacterial meningitis, and brain tumors are most common in children and young adults. In middle-aged and elderly people, cerebrovascular diseases such as cerebral infarction and cerebral hemorrhage are more common due to cerebral vascular sclerosis. Abnormal dilation and contraction of the blood vessels supplying the skull and brain can lead to headache attacks. Migraine attacks, mostly triggered by stress or insufficient rest, are seen in children and young adults as headaches mainly caused by constriction of intracranial blood vessels. Vascular headaches due to hypertension, hypoxia or carbon dioxide storage and drug-induced cerebral vasodilatation headaches are also seen in the elderly. Mostly, they are diseases of the eyes, ears, nose and teeth. Diseases of the eyes include glaucoma, eye trauma, inflammation and tumors; diseases of the nose such as rhinitis, nasopharyngeal tumors, sinusitis and tumors; trauma to the external ear canal, infection, inflammation of the inner ear, etc.; diseases such as dental caries and ophthalmia can also radiate to the head and cause head pain. Inflammatory and traumatic lesions of these organs are more common in children and young adults; tumors and chronic inflammatory lesions are more common in the elderly. 1.Fever: Almost all infectious diseases of all systems with fever can cause headache. 2.Circulatory system lesions: such as hypertension, hypotension and cardiac insufficiency. Changes in blood pressure are an important cause of headache. 3.Respiratory pathology: chronic bronchitis leads to pulmonary insufficiency, etc. 4.Digestive system diseases: liver insufficiency, ulcerative colitis and other diseases. 5, urinary system diseases: such as acute and chronic nephritis, uremia, renal insufficiency, and renal hypertension, etc. 6.Systemic metabolic diseases: such as plateau headache, which is essentially a hypoxic headache. 7.Resulting from systemic poisoning: almost all endogenous and exogenous poisoning are accompanied by headache. 8.Other internal diseases: such as anemia of blood system, hyperthyroidism of endocrine system, menopausal syndrome, and autoimmune and allergic diseases, etc. 9.Neurosis, mental anxiety and tension, menopause syndrome, severe insomnia, and the influence of stimulating substances from smoking and sprinkling, etc. Therefore, if headache occurs, it must not be underestimated and must be checked at the hospital specialist clinic to exclude other pathologies. If other pathologies are excluded and the headache still cannot be relieved by treatment, you can come to the pain clinic for treatment and treatment to slow down or even completely cure your headache by acupuncture and heat therapy, Chinese herbal medicine hot compress and other methods.
