How is headache swelling and pain?

How did the disease of headache come from? Headache has brought inconvenience to the life and work of many friends. When it appeared, the patient was in great pain. Now many people want to prevent it. Let's invite experts to introduce it to you. Physical factors (1) Headache occurs when the pain-causing tissue inside and outside the brain is inflamed, damaged or compressed by tumor, specifically: 1) Headache may occur when intracranial blood vessels are pulled, pulled or displaced. Such as brain tumor, hematoma, abscess, brain edema, venous sinus thrombosis, hydrocephalus and brain tumor. And the decrease of intracranial pressure after lumbar puncture or spinal anesthesia, these factors can lead to the displacement of blood vessels by traction. 2) Vascular relaxing factor. Intracranial and extracranial arterial dilation caused by various reasons can cause headache, such as acute infection inside and outside the skull, toxin, hypoglycemia, hypoxia, carbon monoxide poisoning, alcoholism, brain injury, hypertensive crisis, hypertensive encephalopathy and other factors can all cause vasodilation. Other substances, such as nitroglycerin, can cause blood vessels to dilate, which can cause headaches. 3) The meninges are stimulated. There is pain-sensitive tissue on the meninges. When there is intracranial infection, the blood of inflammatory exudates (such as various meningitis) or sexually transmitted diseases (such as subarachnoid space) stimulates the meninges, or brain edema caused by the above diseases pulls the meninges, which can lead to headaches. 4) Muscle contraction factors. Tension and contraction of head, face and neck muscles are the main causes of tension headache. Muscle contraction will compress the surrounding small blood vessels and tissues, causing them to release chemicals, which will cause pain, irritation and headache. Some jobs, such as sewing, typist, teacher, etc. Working in a fixed posture often makes people's neck muscles tense and contract. Cervical degeneration is also an important cause of tension headache. 5) Nerves are stimulated or damaged. When cranial nerve and cervical nerve are compressed by tumor, or suffer from inflammation such as trigeminal neuritis and occipital neuritis, or are stimulated by trigeminal neuralgia, it can cause head, neck and face pain. 6) Diseases of eyes, ears, nose, sinuses, teeth and neck can spread or reflect to the inside of the head, leading to related headaches. (2) The biochemical factors such as norepinephrine, 5- hydroxytryptamine, bradykinin and prostaglandin dopamine have obvious changes in migraine patients (refer to the above questions). Tension headache may also be the result of chronic inflammation caused by bradykinin. (3) Endocrine factors Clinically, some female migraine patients often report that their headache is relieved during pregnancy, but they may attack or worsen before and after menstruation, which may be related to sex hormones, which has been confirmed by studies. It was found that the concentration of estradiol in blood of migraine patients related to menstruation decreased significantly during headache attack. Therefore, some menopausal headaches can be relieved after using estradiol. (4) Neuropsychiatric factors: Anxiety and anxiety caused by mental or emotional factors are common in headaches caused by neurosis, hysteria and depression. Through the above introduction, you should know something. I hope my friends can try their best to prevent headaches after learning about it.
