Primary headaches can have many causes, in the majority of cases they can be caused by: genetic predisposition, external triggering factors (physical and mental stress, caffeine abuse, prolonged fasting, high blood sugar, incorrect posture, dental malocclusion, alteration in the circadian rhythm, alcohol abuse, smoking, inappropriate use of medication), alterations of blood vessels, veins and artheries (occlusion, compression or traction), inflammation, extracranial and paraspinal muscle contracture or compression, cranial nerves inflammation or meninx infections ( lining surrounding the brain).
In other cases, headaches can be caused by a brain injury or more rarely they can be a sign of a more serious disease (secondary headaches).

Primary headaches are the most common type of headache and the main kinds are:
It’s the most common and less painful primary headache and it mainly depends on the involontary and constant contraction of the nape, front, temple, neck and shoulders muscles. Attacks last from half an hour to a week.

It is the less common form of primary headache, but the most serious. it occurs in cyclical patterns and is one of the most painful types of headaches. Bouts of frequent attacks, known as cluster periods, can last from weeks to months, usually followed by remission periods when the headaches stop.

It is believed that specific hormonal and neurogenic alterations are involved.
