People with chronic migraine headaches, for instance, may discover it hard to attend work or school regularly.
Headaches can be due to variety of reasons and they are classified as
1-What is Primary Headaches?
Primary headaches are stand-alone illnesses caused directly by the over activity of, or problems with, structures in the head that are pain-sensitive.
This includes the blood vessels, muscles, and nerves of the head and neck. They may also result from changes in chemical activity in the brain.
These are due to problems with pain receptors in head. It isn't a symptom of an underlying disease. Most common causes of primary headaches are,
Cluster headache: Exact cause yet unknown but Believed to be due to deformity in hypothalamus. Headaches occur in cyclical pattern with clock like regularity in 24 hours cycle with headache generally occurring around one side of head or excruciating pain near one eye and stuffy or runny nasal passages.
Migraine: Intense throbbing or a pulsing sensation in one area of the head and is commonly accompanied by nausea, vomiting, and extreme sensitivity to light and sound. Some migraines are preceded or accompanied by sensory warning symptoms (aura), such as flashes of light, blind spots, or tingling in your arm or leg.
Trigeminal autonomic cephalalgia (TAC): including cluster headache and paroxysmal hemicrania
Tension Headache: generally a diffuse, mild to moderate pain in your head that's often described as feeling like a tight band around your head. A tension headache (tension-type headache) is the most common type of headache, and yet its causes aren't well understood. The most common theories support a heightened sensitivity to pain in people who have tension headaches and possibly a heightened sensitivity to stress ( so the name tension headache)
· Exercise headaches: Exercise headaches occur during or after sustained, strenuous exercise. Some activities associated with exercise headaches include running, rowing, tennis, swimming and weightlifting,there are of 2 types of exercise headache
a- primary (harmless, aren't connected to any underlying problems)
b- secondary ( caused by an underlying, often serious problem within the brain, such as bleeding or a tumor, or outside the brain, such as coronary artery disease)
Sex headache- Yes there is a headache of this type :) Sex headaches are brought on by sexual activity — especially an orgasm. a dull ache in your head and neck that builds up as sexual excitement increases. Or, more commonly, you may experience a sudden, severe headache just before or during orgasm. reasons are, A widening or bubble in the wall of an artery inside your head (intracranial aneurysm), An abnormal connection between arteries and veins in the brain (arteriovenous malformation) that bleeds into the spinal fluid-filled space in and around the brain, Bleeding into the wall of an artery leading to the brain (dissection), Stroke, Coronary artery disease, Use of some medications, such as birth control pills, Inflammation from certain infections.
What is Secondary Headaches?
Secondary headaches are symptoms that happen when another condition stimulates the pain-sensitive nerves of the head. In other words, headache symptoms can be attributed to another cause or A secondary headache is a symptom of a disease that can activate the pain-sensitive nerves of the head. Any number of conditions may cause secondary headaches.
It could be due to,
· 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)
· Congenital heart disease in adults
· Dental problems
· Ear infection (middle ear)
· Encephalitis (brain inflammation)
· Giant cell arteritis (inflammation of the lining of the arteries)
· 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)
· Trigeminal neuralgia (disruption of the nerve connecting the face and brain)
