Why a headache
Tissue sensitivity to pain depends on the density of the nerve endings on the surface thereof. Any tissue completely insensitive to pain. The nerves of the head is in the skin, subcutaneous tissue, muscle and tendon helmet, vascular soft tissues of the head, the periosteum of the skull, meninges, intracranial arteries and veins. During stimulation of each of these structures is a headache.
Types of headaches
Headaches may be vascular, resulting from muscle strain, as a result of increased intracranial pressure, neuralgic, mixed and the resulting abnormalities in the pain receptors (nerve endings).
Stimulation of vascular receptors occurs when excessive stretching of the arteries that can arise as under reduced pressure

(vasodilation and blood stagnation therein), but also at elevated (increased blood volume). Poor tone of veins also causes stagnation of blood in them and irritation of pain receptors.
In patients with hypertension
Hypertension - dangerous consequences
(high blood pressure), headache, pulsating character gets sick say "knock on the head."
Hypotension (low blood pressure) is characterized by a dull oppressive and bursting with pain.
Venous headache occurs when deterioration in the outflow of venous blood, the veins expand and overflow with blood. It is dull, arching and amplified by a long stay in a horizontal position. She often appears in the morning and gradually passes after getting up.
Muscular headache occurs with prolonged tension or compression of the muscles of the head. The person experiences at the same time a feeling of compression bandage, or tightening of the head, as if on his head wearing a hoop. This headache may initially occur in the frontal or the nape area, then it rapidly spreads to the whole head, being transferred from muscle to muscle, tendon through which a helmet covers our head.
Most often, this pain occurs after emotional stress
How to beat stress? Create an oasis
or excessive physical stress. After rest and relaxation headache passes.
Liquorodynamic headache occurs in violation of the intracranial pressure (as with increasing and with decreasing). This increase in intracranial pressure occurs in some areas, causing tension there meninges, blood vessels and nerves inside the skull. Headache while arching, patients are under pressure "from the depths of the brain." It is under such serious diseases as tumors, abscesses (abscesses, limited capsule), brain injury, meningitis, and others.
Decreased intracranial pressure can occur after removal of cerebrospinal fluid. Headache with the enhanced standing.
Neuralgia has a number of features, which in most cases make it easy to distinguish from other types of headaches. The first sign of pain - an attack lasts a few seconds or minutes, but attacks follow one another at short intervals, causing the patient to suffer painfully for hours and days. The second sign neuralgic pain - the existence of special zones (trigger or triggers), which triggers an irritation. Even just a touch to this area can cause a headache. The third feature - the pain gives to neighboring or distant sites. The pain is usually sharp, penetrating, sharp, "like an electric shock." At the moment of pain the patient dies, he is afraid to even open his mouth and once again blink.
Sometime during the attack to the same type of pain joins another. For example, vascular pain joins muscle. Mixed headache occurs, for example, meningitis, when there is a violation likvorodinamiki edema meninges, increased intracranial pressure, and other mechanisms of pain.
Sometimes the headache occurs without any apparent reason. This pain is called psychogenic pain or headache hypochondriac. Obviously, such a headache is a result of abnormalities in the pain receptors in the head. Most often it arises against metabolic disorders

. The name does not mean psychogenic. she invented the sick.
Many types of headaches, they have a different mechanism, and hence are treated differently. To understand how and what to shoot a headache, the doctor will help you.
