A variety of causes can lead to intractable headache, such as brain tumor, encephalitis, trauma, vascular spasm, vascular stenosis, blood circulation disorder, rhinitis, nerve compression, cervical spondylosis, etc. When headaches recur, you should go to the hospital for examination, such as head CT, head MRI, cerebral angiography, cerebrovascular ultrasound, etc. There are two most common types of intractable headaches: vascular headache and neurological headache. Vascular headache is caused by the abnormality of the blood vessel structure in the head, which is characterized by irregular attacks of headache, mainly swelling pain, sometimes pulsating headache, accompanied by dizziness, nausea and even vomiting, which can last for hours or even days, and requires bed rest in severe cases. At present, cerebral angiography can clarify the blood vessel and location of the lesion, and on this basis, interventional treatment or minimally invasive surgery can cure the headache. Neuropathic headache is characterized by pinprick-like pain in a certain area of the head, which can be in the form of strips or slices of pain in the head area. The pain is mostly radioactive in nature, and each attack lasts for a short period of time, but can be recurrent and severe, mostly without nausea and vomiting. This kind of pain is mostly caused by nerve compression, so it is most crucial to clarify the nerve of pain and the site of compression, and the diagnosis can be confirmed with the help of doctor’s examination and imaging, and the treatment is preferred to remove the cause. Common misconceptions: (1) not paying attention to it: thinking that headache will not be a big deal and losing the best time for treatment; (2) blind treatment: when headache occurs, a variety of treatment measures are used arbitrarily without clear diagnosis and etiology, which not only fails to cure but also tends to cover up the real condition; (3) mistakenly thinking that they have an incurable disease, believing what others say, no longer taking active treatment and suffering from pain for a long time; ( (4) Many patients have been suffering from pain for more than 10 years, but they have never been examined for the real cause of the disease, so not only can they not be cured but also lose confidence, and they may even have mental abnormalities, so it is recommended that all headache patients ask themselves what is the disease they have before receiving treatment? What is the cause? How can they be cured completely? The key is not to treat blindly but to treat the cause.
