What causes really bad headaches?
1. Migraines
Migraines are a neurological condition that causes severe headaches. They are often accompanied by other symptoms, such as nausea, vomiting, and sensitivity to light and sound. Migraines are thought to be caused by a combination of genetic and environmental factors.
2. Tension headaches
Tension headaches are the most common type of headache. They are usually mild to moderate in severity and can last for anywhere from 30 minutes to several days. Tension headaches are thought to be caused by muscle tension in the head and neck.
3. Cluster headaches
Cluster headaches are rare but extremely painful headaches. They occur in clusters, which can last for several weeks or months. Cluster headaches are more common in men than women and they typically begin in adulthood. The exact cause of cluster headaches is unknown, but they are thought to be related to changes in the body's hypothalamus.
4. Sinus headaches
Sinus headaches are caused by inflammation of the sinuses. They are often accompanied by other symptoms, such as nasal congestion, facial pain, and fever. Sinus headaches are usually treated with over-the-counter pain relievers and decongestants.
5. Caffeine headaches
Caffeine headaches can occur in people who are regular caffeine users. They are typically mild to moderate in severity and can last for several hours. Caffeine headaches are thought to be caused by withdrawal from caffeine.
6. Rebound headaches
Rebound headaches are caused by overuse of pain relievers. They are typically worse than the original headaches that the pain relievers were taken to treat. Rebound headaches can be difficult to treat and may require medical attention.
7. Serious medical conditions
Headaches can also be a sign of a serious medical condition, such as a brain tumor, aneurysm, or infection. If you experience a sudden, severe headache or a headache that is accompanied by other neurological symptoms, such as vision changes, weakness, or numbness, it is important to see a doctor immediately.
