Migraines are different from ordinary headaches. Many people may have a headache from time to time in their lives and usually just take some medicine and rest. Migraine is the most common type of primary headache in clinical practice. It is mainly characterized by episodes of moderate to severe, throbbing headache and is not easily treated. Of course, migraines can be mild or severe. Mild migraines may be infrequent and the pain is not severe, and may have little impact on life and work, and can be relieved by taking pain medication or resting in a quiet environment. Severe migraines, on the other hand, are tricky and not so easy to relieve. What happens to the most severe migraines? Intractable migraines are often accompanied by symptoms such as nausea and vomiting, fear of light and noise, etc. There is a distinct interval when the migraine does not strike as normal, but when it strikes, it is very intense, painful, and frequent. Some patients hit their heads against the wall and roll all over the floor when they have an attack, and some patients are so unbearable that they become depressed or even commit suicide. Therefore, migraine is very scary and must be treated early. For intractable migraine, taking pain medication, acupuncture and physical therapy are often not effective. At present, the treatment of intractable migraine with vascular nerve compression by microvascular decompression can achieve very good clinical results. It is understood that microvascular decompression can reach the root of the migraine lesion and release the vascular nerve compression on the scalp, which is the root cause of pain, so that migraine can be effectively treated.
