I am frequently suffering with headache may I know the reason behind the problem.

Question

Headaches are generally classified by cause:

Primary headaches
A primary headache is caused by problems with or overactivity of pain-sensitive structures in your head. A primary headache isn't a symptom of an underlying disease. Chemical activity in your brain, the nerves or blood vessels of your head outside your skull, or muscles of your head and neck ? or some combination of these factors ? may play a role in primary headaches. Some people may carry genes that make them more likely to develop such headaches.

The most common primary headaches are:

Cluster headache
Migraine (with and without aura)
Tension headache (medically known as tension-type headache)
Trigeminal autonomic cephalalgia (TAC), including cluster headache and paroxysmal hemicrania
There are other headache patterns that are generally considered types of primary headache but are less common. These headaches have distinct features, such as an unusual duration or pain associated with a certain activity. Although these headaches are generally considered primary, each of them could be a symptom of an underlying disease. These headaches include:

Chronic daily headaches
Cough headaches
Exercise headaches
Sex headaches
Some primary headaches can be triggered by lifestyle factors, including:

Alcohol, particularly red wine
Certain foods, such as processed meats that contain nitrates
Changes in sleep or lack of sleep
Poor posture
Skipped meals
Stress
Secondary headaches
A secondary headache is a symptom of a disease that can activate the pain-sensitive nerves of the head. Any number of conditions ? varying greatly in severity ? may cause secondary headaches. Sources of secondary headaches include:

Acute sinusitis
Arterial tears (carotid or vertebral dissections)
Blood clot (venous thrombosis) within the brain ? separate from stroke
Brain aneurysm (a bulge in an artery in your brain)
Brain AVM (an abnormal formation of brain blood vessels)
(both cancerous and noncancerous)
Carbon monoxide poisoning
Chiari malformation (structural problem at the base of your skull)
Concussion
Congenital heart disease in adults
Dental problems
Ear infection (middle ear)
Encephalitis (brain inflammation)
Giant cell arteritis (inflammation of the lining of the arteries)
Glaucoma
Hangovers
Influenza (flu)
Intracranial hematoma (blood vessel ruptures in the brain)
Medications to treat other disorders
Meningitis (inflammation of the membranes and fluid surrounding your brain and spinal cord)
Monosodium glutamate (MSG)
Overuse of pain medication
Panic attacks and panic disorder
Post-concussion syndrome
Pressure from tight-fitting headgear, such as a helmet or goggles
Pseudotumor cerebri (increased pressure inside the skull)
Toxoplasmosis
Trigeminal neuralgia (disruption of the nerve connecting the face and brain)
