Some Adults, children and adolescents, male or female, are afflicted by constant and recurring headaches. A person experiences headache pain resulting from the interaction occurring between the brain, blood vessels, and surrounding nerve areas. During the course of a headache, specific nerves of the blood vessels as well as the head muscles are triggered which transmit pain signals to the brain.
The main mechanics of how this pain is triggered and then transmitted to the brain are abnormally active nerve cells send signals to the blood vessels, which causes constriction, along with the dilation of these vessels as well as the subsequent discharge of prostaglandins, serotonin, and various other inflammatory substances which cause the pulsation to become painful. Yet, the the reason why still remains a major mystery to medical science.
Sudden headaches are typically caused by an illness, infection, cold or fever. Sinusitis, pharyngitis or ear infection may also be the reason for sudden headaches this includes head trauma or very rarely as an adverse result of a serious medical condition.
