1. Cluster HeadacheCluster headaches are less common than migraines or tension headaches. They usually occur over one eye, and they affect more men than women. A cluster headache can appear suddenly and cause a severe, debilitating pain on one side of the head. This type of headache is recurring, and sufferers may experience an episode several times a dayduring a period of time that can range anywhere from two weeks to three months. Warning Signs Cluster headaches can be managed, but there are warning signs to look for. If you're suffering from cluster headaches and you notice your eye turning red, or the pain is so severe that it's affecting your ability to function, it's time to see a doctor. An aneurysmcan start with a sudden severe headache, which may be accompanied by neck stiffness and intolerance of bright light.
2. Thunderclap HeadacheThunderclap headaches are true to their name — they grab your attention like a sudden clap of thunder. The pain of these sudden and severe headaches peaks within a minute of onset, and they may start fading after about an hour. About 80% of those who experience a thunderclap headache have a triggering event, such as exercise or sexual activity - something that had their blood pumping. Warning Signs A thunderclap headache can be a warning sign of something potentially life-threatening. It could indicate bleeding in the brain, a stroke, aneurysm or a brain tumor. If you experience a thunderclap headache, go get things checked out by a doctor.
3. Headache After a Head InjuryAt one point or another, we're probably all going to get hit in the head with something. Whether it's a basketball, a Frisbee or a low-hanging light, we'll all experience a bump on the head on occasion. Depending on how severe your injury is, it could disrupt the normal function of the brain. If your injury is serious enough to cause a concussion, you need to see a doctor. Warning Signs Symptoms of a concussion might not start right away. They could start days or even weeks after a head injury. These symptoms can include a headache, neck pain, nausea, dizziness and fatigue. A brain injury can be extremely serious. If there's even a chance of brain injury or a concussion, you'll want to take a trip to the hospital.
