The mechanism of headache of physical injuries usually occurs in two ways:

– Injury to the organism increases the production of chemical mediators, acting on pain receptors, thereby causing headache symptoms. These mediators are usually kinins, serotonin, prostaglandins.

– Physical injury causes mechanical stimulation of pain receptors, such as twisting, stretching, enema of blood vessels or other nociceptors.

From this mechanism, it is possible to identify more than 70 groups of causes of headache, in which most causes are benign. However, if the headache occurs continuously, along with other unusual symptoms, it may be a sign of a serious illness.
