Headache is one of the most common complaints.
This discomfort has been experienced by almost every person at least once in their life.
The pain appears in any part of his head. The pain may complain of both on one side or the other, be expressed at one particular point or spread.
Manifested by sharp, stinging, as well as dull pain, you may even feel a kind of explosive pulsation. The headache may come on suddenly and not last for an hour or even be chronic for a few days.
The headache is caused by irritation of the nerve endings (so-called receptors) that are placed inside and outside the skull. When irritated, these receptors send a signal through nerve fibers to the brain, where information is processed - the end of the chain reaction is the sensation of pain.
In a large percentage of clinical cases, headache is a symptom of latent pathology or adverse effects on the body - it is necessary to make a timely diagnosis, the appropriate course of treatment.
Headaches are generally classified by cause:
