a lot of things can cause headaches. headaches can be either emotionally caused or physically caused. stress/ tension headaches are rather common. the muscles tighten in the back of the neck in the sub-occipital area of your skull. when they tighten, blood flow becomes limited and the headache starts to come on. either emotional or physical headaches should be treated by simple neck stretches and by adding heat for 15 minutes.

A tension headache is a condition involving pain or discomfort in the head, scalp, or neck, usually associated with muscle tightness in these areas. Tension headaches result from the contraction of neck and scalp muscles. One cause of this muscle contraction is a response to stress, depression or anxiety. Any activity that causes the head to be held in one position for a long time without moving can cause a headache. Such activities include typing or use of computers, fine work with the hands, and use of a microscope. Sleeping in a cold room or sleeping with the neck in an abnormal position may also trigger this type of headache. Other causes include eye strain, fatigue, alcohol use, excessive smoking, excessive caffeine use, sinus infection, nasal congestion, overexertion, colds, and influenza. Tension headaches are not associated with structural lesions in the brain.

Depends on what's causing the headache.  Try massage, meditation (including running, tai chi, meditation, yoga, or anything that requires your attention but not your intense concentration) sleep or food (avoide caffeine because it constricts the blood vessels and make it so you can't sleep).  If that doesn't work, the cause may be biochemical... see your doc.

Headaches have a wide variety of causes, ranging from eyestrain, sinusitis and tension to life-threatening conditions such as encephalitis, meningitis, cerebral aneurysms and brain tumors. When the headache occurs in conjunction with a head injury the cause is usually quite evident; however, many causes are more unclear. The most common type of headache is a tension headache. Some experience headaches when dehydrated; caffeine withdrawal is another common cause.\n\nTension Headaches:\n\nThe exact cause of tension headaches is still unknown. It has long been believed that they are caused by muscle tension around the head and neck. Although muscle tension may be involved, there are many forms of tension headaches and some scientists now believe there is not one single cause for this type of headache. One of the theories is that the pain may be caused by a malfunctioning pain filter which is located in the brain stem. The view is that the brain misinterprets information, for example from the temporal muscle or other muscles, and interprets this signal as pain. One of the main molecules which is probably involved is serotonin. Evidence for this theory comes from the fact that tension headaches may be successfully treated with certain antidepressants. Another theory says that the main cause for tension type headaches and migraine is teeth clenching which causes a chronic contraction of the temporalis muscle. Patients with chronic tension-type headache have increased muscle and skin pain sensitivity, demonstrated by low mechanical, thermal and electrical pain thresholds. Hyperexitability of central nociceptive neurons (in trigeminal spinal nucleus, thalamus, and cerebral cortex) is believed to be involved in the pathophysiology of chronic tension-type headache.

High blood pressure will not cause a migraine but Reserpine, a medication for high blood pressure will.\n\nHowever, hypertension can cause a headache.  A hypertension headache is suffered by people with very high blood pressure. It is usually worse in the morning, the pain seems to "band" the head.

You should first check your eyes, if your sight is bad it can lead into constant headaches; especially at the end of the day.  \nYou should also try to identify if it's only a headache or possibly a migraine-they are usually accompanied by sensitivity to light, sound, smell; nausea, or diziness-. Some migraines are triggered by stress, but some food, like chocolate, spices, orange juice, or dairy, can also cause them.  \nYou should check with your doctor to find out if you need exams, maybe a cat scan.  Hope it helps

Traditional theories about headaches link tension type headaches to muscle contraction, and migraine and cluster headaches to blood vessel dilation (swelling). Pain-sensitive structures in the head include blood vessel walls, membranous coverings of the brain, and scalp and neck muscles. Brain tissue itself has no sensitivity to pain. Therefore, headaches may result from contraction of the muscles of the scalp, face or neck; dilation of the blood vessels in the head; or brain swelling that stretches the brain’s coverings. Involvement of specific nerves of the face and head may also cause characteristic headaches. Sinus inflammation is a common cause of headache. Keeping a headache diary may help link headaches to stressful occurrences, menstrual phases, food triggers, or medication. Tension-type headaches are often brought on by stress, overexertion, loud noise, and other external factors. The typical tension-type headache is described as a tightening around the head and neck, and an accompanying dull ache. Migraines are intense throbbing headaches occurring on one or both sides of the head. The pain is accompanied by other symptoms such as nausea, vomiting, blurred vision, and aversion to light, sound, and movement.\nMigraines are often triggered by food items, such as red wine, chocolate, and aged cheeses. For women, a hormonal connection is likely, since headaches occur at specific points in the menstrual cycle, with use of oral contraceptives, or the use of hormone replacement therapy after menopause. Cluster headaches cause excruciating pain. The severe, stabbing pain centers around one eye, and eye tearing and nasal congestion occur on the same side. The headache lasts from 15 minutes to four hours and may recur several times in a day. Heavy smokers are more likely to suffer cluster headaches, which are also associated with alcohol consumption.

Headaches are usually caused by inflammation of the blood vessels in your brain.  The inflammation draws blood to your brain and vascular contraction forces blood out of the blood vessels.  Your head can't expand because your skull is hard.  This puts pressure on your brain and this causes pain.\nThis is why people use antiinflammatory agents for headaches (Aspirin, Ibuprofen, Aleve).  Serotonin is involved in the inflammatory cascade and antimigraine drugs like Imitrex work by modulating this pathway.

See your doctor, please.  If it feels like a sinus headache, you might have a sinus infection.  IF you have a sinus infection, sinus pills won't help...you will need an antibiotic.  But a visit to the doctor will pinpoint the cause of your headache, even if it is not sinus related.  Please see a doctor instead of continuing to suffer.

headaches are almost always dehydration. unless you have chronic or migrane headaches then it could be something else.. but almost all normal headaches are caused by not enough water.
