Tsefalgiya - the most common symptom of various diseases, which is localized on the level of the orbit to the suboccipital region.Facial pain, with a wider examination tsefalgii are also included in this concept.This expression usually refers to the venous sinuses, large arteries and cerebral circulation basal dura mater heads.brain.Pain receptors are saturated with all of scalp tissue
causes of headaches
In most cases, the headache is a vascular origin and arises as a result of overfilling the blood vessels, while stretching the vessels pulse volume of blood, and as a result the volume of the process by pulling the vessels.
When excessive stretching of blood vessels, there are synchronous with the pulse, rhythmic stupid "blows to the head."If a problem arises with the vessels in one zone of the vascular - throbbing occurs only at a specific location of the head and is usually terminated when squeezed resulting artery.
Throbbing headache occurs when excessive stretching of t
With the development of extreme hypotension occurs swelling and impaired vascular wall permeability, thereby ceases to be a throbbing pain, becoming oppressive, stupid, bursting and bursting (such transformation can be seen as the development of a migraine).
Venous headache is caused by dilation of intracranial veins, because of their excessive blood supply that comes from - insufficient venous tone in diseases such as infectious - allergic vasculitis, vegetative - vascular dystonia and so on. There is a dull arching pain (localized mainly in the back of the head)and a feeling of heaviness in the head.Venous tsefalgiya may be aggravated by straining ( constipation , heavy physical work), in continuous operation with low head bowed, when tighten tie and wearing a tight-collared shirts, an increase in intrathoracic pressure.Also, long-term hypotension veins characterized by such symptoms as swelling of the mucous membranes of the throat and nose, dilated veins in the fundus, pasty and eyelid edema and soft tissues of the face (in the morning hours, these symptoms are most noticeable).
headache may also occur if you change the composition of the blood (increased its viscosity, have a tendency to platelet aggregation occurs, the red blood cells lose their elasticity and so on.).Consequently, the intracranial blood circulation increases, resulting in tissue hypoxia.This kind tsefalgii characterized by varying the intensity of dull pain, drowsiness, lethargy, weight (ringing, noise) in the head.Changes in the blood occur in many diseases: atherosclerosis, hypertension, blood diseases, diseases of internal organs.
most common cause of chronic headache is tsefalgiya psychogenic.Constant pain that does not pass for several years, often indicative of the doldrums.Also talk about depression and about fifty percent of the pain in the face.
neuralgia tregimenalnogo origin, hypertension, or common migraine diagnosis cephalgia is not particularly difficult.In other cases it is necessary to conduct a thorough follow-up.Analysis of the fundus and blood pressure are very solid in the diagnosis of this condition.Echoencephalography is one of the main methods of diagnosis.In cases of prolonged or intense headaches carried out a study of cerebrospinal fluid, kraniograficheskoe study and computed tomography
Because the cause of headaches in addition to minor deviations may be quite serious disease in tsefalgii lasting more than a day, be sure to consult your doctor, who after the necessary comprehensive survey appoint adequate treatment, which will depend on the cause of this condition.
