    In ancient Greece, the best-known remedy for a long-standing headache was to drill a small hole in the skull to drain supposedly infected blood. Fortunately, doctors today don’t resort to power tools to cure headaches, but we still have a lot to learn about this ancient ailment. Dan Kwartler shares what we know (and don't know) about headaches.

    Hnnngh I want to watch this video to learn more about where headaches come from, but as someone who gets regular migraines, just hearing "headache" is enough to induce one for me.
    Still seems like a good video so far though!

    The Man Who Mistook His Wife for a Hat is an excellent book. Migraines can last longer than 3 days. My longest one was 6 days, and I've had several last 4 or 5 days as well.

    i had a headache for over a week, i couldn't even function anymore I just wanted it to end. turns out i must've been super dehydrated, everytime i drank water i felt nauseous, so i was avoiding it. might've had a stomach virus, will never know because i didnt go to the doctor. i'm too broke to go to the doctor but luckily is finally gone.

    I rarely get headaches, but when I do, they intensify with certain head positions. I classify them as sinus headaches and take Sudafed and ibuprofen which usually knock it out. I never experience any facial swelling or facial pain with them though... Does anyone have any idea if these are truly sinus headaches?

    Actually in some countries (like mine) there are abortive medication, 'regular medication' and preventive medication for both cluster and migraine.
    Cluster headache is typically treated using oxygenation and prevented by using non-dihydropyridine calcium canal blocker while Migraine is aborted by using -triptan drugs and some doctors preferred using Beta blockers to prevent migraine.
    However, the usage of over-the-counter analgesics are useful too in some patients.

  • TheIronHunter
    TheIronHunter 4 days ago

    I used to get migraines that lasted anywhere from 12-48 hours. So painful that it would lead me to tossing and turning laying on the couch. Praying for it to go away. It would often lead to me throwing up multiple times throughout the night. I used to get these once or twice a month. After 4 years of these I started to go to a chiropractor and about 2-3 months in of going twice a week. I started to see my migraines be less frequent. Today I havent had one in since i dont even know. Doctors do not like chiropractors because they do not fully understand them, but they do help. If you suffer from migraines trust me go see a chiropractor. They are expensive but its worth it. Ill never forget that feeling of pain.

    For me personally, I get cluster headaches very rarely, but when I do it's usually from a very abnormal sleep schedule combined with lack of sleep. I'll go to be one at 8:00pm then the next day at 2:00am while waking up at the same time which is usually 7:00am. Stress from work may have contributed to it, but stress on it's own will not give me a cluster headache. I can see why it would be hard to pinpoint though since diet, weird sleeping position, and exercise can also play a role. I would have to say the quality and length of sleep is the biggest factor since your brain needs that time in order to remove "toxins" and if those "toxins" pile up enough then they cause inflammation in other areas of the brain? I'm not a scientist or doctor, but that would be my educated guess based off of personal experience and a tiny amount of research.

    About migraine, i once heard in a documentary that consuming milk products of any kind, COULD cause migraine.
    A special clinic, idk in swiss, is researching that and they dont really have a definite proof, but their theorising about the influence of cow-growing-hormones in the mother milk.
    They say our human grown out body doesn't react well to that kind of hormone thats supposed to be for cow babys.
    As i said, there is no real proof because their studys are too low scale or something , but in this film, there were people asked to deny the use of milk products
    (everything: means, cheese, bread, cake etc., chocolate)
    for two weeks or so, completely!
    And many of them said the migraine was gone.
    Sooo, in case some people here have strong migraines and you dont have a fix and the doctors cant help either, maybe you may try this?
