Headache is not a disease, but one of the most common clinical symptoms in neurology. According to different causes, headache is divided into two major categories: primary headache and secondary headache. There are four main types of primary headaches. Migraine: Migraine is the most common headache in neurology and is triggered by vasodilatory dysfunction. Many people think that migraine is only a kind of side pain, but in fact, it also manifests as pain on both sides or alternating pain, mostly orbital, postorbital or frontotemporal area (temple) ergogenic pain, and patients often have related symptoms such as dizziness, fear of light, fear of noise, nausea, and in severe cases, vomiting. Migraine is divided into four phases, the first phase is before the onset of the disease, the intracranial blood vessels are in a constricted state, the application of vasodilators; the second phase is the onset of the disease, the blood vessels are in a dilated state, the application of drugs to improve overdilation; the third phase of the blood vessel wall appears aseptic inflammation, becoming a persistent headache; the fourth phase is the secondary contraction of the cranial muscles and cervical muscles headache. The doctor should take a detailed medical history, give the patient a more comprehensive physical examination, and combine it with auxiliary means such as cerebral hemogram (a kind of ultrasound specializing in looking at intracranial blood vessels) to use the medication in a targeted manner. Patients should not blindly take drugs used for vasodilator-like symptoms, especially not during the onset of the disease, so as not to have the opposite effect. Tension headache: Tension headache is caused by impaired blood circulation in muscles and myofascia and persistent muscle contraction and ischemia, and patients often feel a sense of “pressure and constriction” in the head. It is the most common type of chronic headache. It is second only to migraine in terms of incidence, and is mostly suffered by students who are under stress from studies or office workers who are under stress from work. It can be treated with muscle relaxation medication and psychological support. Neurogenic headache: It is more common and has a crossover part with tension headache. Patients should be treated with relaxation therapy based on appropriate medication and psychological support to regulate or restore the balance of excitation and inhibition of the human nervous system. Cluster headache: This type of headache is less common and manifests as a brief, intense, explosive pain, often accompanied by symptoms such as bloodshot eyes, tearing and nasal congestion, with nap and early morning attacks being the most common, with male onset being more common. There are also a variety of secondary headaches: headaches caused by head and neck trauma, intracranial growths, intracranial infections (such as encephalitis), cerebral aneurysms, etc. Chronic sinusitis and glaucoma can also cause headaches. In addition, Director Deng especially emphasized that there is a kind of drug-dependent headache, which is caused by the improper use or long-term use of some drugs for headache treatment. For example, over-dependence on aspirin and headache powder can cause or aggravate headache, mostly seen in women aged 30 to 40. Headaches are easily misdiagnosed, mostly as vasoneurotic headache, and some are misdiagnosed as Meniere’s syndrome when accompanied by dizziness, and some are misdiagnosed as serious diseases such as vascular stenosis, which invariably increase the psychological pressure of patients. In fact, whether it is primary headache or secondary headache, there are usually accompanying symptoms in addition to the difference in pain sensation. For example, headache caused by glaucoma is often accompanied by eye swelling due to intraocular hypertension. Therefore, doctors should correctly diagnose the cause of headache according to the different clinical symptoms and examination results of the patients’ patients, and then give targeted medication, and also give psychological support treatment, and antidepressant and anxiety treatment if necessary. Through standardized treatment, the interval between attacks is prolonged, the degree of attack is reduced, and some are thus clinically cured. Note: Once symptoms are detected, attention should be paid to early detection, early diagnosis and early treatment. Choose the right treatment is the key, do not have the disease to seek medical help, causing serious injury. It is recommended to go to a regular public hospital for standardized treatment so that patients can recover as soon as possible.
