common causes of headache are:
1-The most common cause of headaches is prolonged tension or stress. These are called tension headaches or muscle-contraction headaches. Virtually everyone suffers from this at some time. Muscles in your scalp, neck, and face tighten and contract, causing spasms and pain. Psychological factors such as anxiety, fatigue (e.g., eyestrain), and stress (ex long periods of concentration) as well as mechanical factors such as neck strain (e.g., working on a computer for prolonged periods) are often the culprits behind a typical tension headache.
2-Migraines are generally more severe and can be debilitating. The cause of migraine is not known but many trigger factors are recognized. These include hormonal changes (during a woman's menstrual cycle), certain foods (e.g., chocolate, aged cheeses), beverages (e.g., red wine), strong odours, lack of sleep, and even stress. It is not uncommon to experience mixed tension-migraine headaches.
3-Sinus headaches are less common than people think. They can occur after a bout of upper respiratory infection, such as a cold. Along with the headache, people often have a runny or stuffy nose. Sinus headaches are caused when bacteria invade and infect the nasal sinuses.
4-Cluster headaches are a relatively uncommon type of headache. They tend to occur in clusters over a few days, weeks, or months with long headache-free periods lasting from months to years.In some cases, they are triggered by alcohol.The cause is not known.
5- "ice pick" headache are severe headaches that occur suddenly, causing a few seconds of intense pain at a small, localized spot.
