Why do you get headache

During antiquity, migraines were regarded as severe ailments.

The afflicted beseeched Asclepius, the deity associated with medicine.

In the event that the discomfort persisted, a healthcare professional would administer the most well-known treatment—doing a minor incision in the cranium to extract purportedly contaminated blood.

Trepanation, an urgent technique, frequently resulted in the substitution of the headache with a more enduring ailment.

Thankfully, modern physicians no longer rely on power instruments to treat headaches.

However, much remains to be learned regarding this age-old ailment.

As of today, migraines have been categorized as either primary or secondary affairs.

They are the condition themselves and not symptomatic of an underlying disease, injury, or condition.

However, we shall return to them shortly, as although primary headaches comprise 50% of reported cases, there is significantly more knowledge regarding secondary headaches.

These are precipitated by various underlying health conditions, including but not limited to caffeine withdrawal, dehydration, head and neck trauma, and cardiovascular disease.

More than 150 diagnosable varieties have been categorized by physicians, each with unique potential causes, symptoms, and treatments.

However, we shall use a single prevalent instance—a sinus infection—as an illustration.

A system of cavities located behind the foreheads, noses, and upper cheekbones are the sinuses.

Our immune system heats the infected sinuses, roasting the bacteria and significantly enlarging the cavities beyond their normal dimensions.

In addition to exerting pressure on the cranial arteries and veins, the enlarged sinuses also affect the musculature of the head and neck.

In response, their nociceptors, which are pain receptors, become active. This signals the brain to secrete an abundance of neuropeptides, which cause inflammation of the cranial blood vessels, resulting in cranium swelling and hyperthermia.

When combined with hypersensitive muscles of the head, this distress produces the excruciating, throbbing pain of a headache.

Headache pain does not always result from edema.

Muscle tension and nerve sensitivity that is inflamed contribute to the distinctive pain experienced during each headache.

However, every instance involves a response to a cranial irritant.

The etiology of primary headaches is still unknown, whereas the cause of secondary headaches is readily apparent.

The three most prevalent kinds of primary headaches—recurrent, long-lasting migraines; intensely painful, rapid-fire cluster headaches; and tension headaches—remain under investigation by scientists as potential triggers.

Tension headaches are characterized by the sensation of a constricted band being pulled around the skull, as the name implies.

As a result of the increased tenderness of the pericranial muscles caused by these migraines, they pulse agonizingly with oxygen and blood.

Although patients cite tension, dehydration, and hormonal fluctuations as triggers, these do not quite correspond with the symptoms.

For instance, the frontal lobe shrinks away from the skull during dehydration headaches, resulting in forehead swelling that is not located at the site of discomfort during tension headaches.

Although scientists have proposed various hypotheses regarding the precise cause, including hypersensitive nociceptors and constricted blood vessels, no one knows for certain.

In contrast, the majority of headache research focuses on primary migraines that are more severe.

Recurrent headaches that cause a viscous sensation on the cranium and can last between four hours and three days are known as migraines.

These assaults are severe enough to overwhelm the brain with electrical energy in 20% of instances, causing sensory nerve endings to become overly stimulated.

Auras are hallucinations caused by this, which may include tingling sensations and the perception of flickering lights and geometric patterns.

Another form of primary headache, cluster headaches are characterized by stabbing, burning pain that emanates behind one eye and results in a red eye, constricted pupil, and drooping eyelid.

What can be done to remedy these conditions, which have a profound impact on the quality of life for numerous individuals?

The majority of secondary cases and tension headaches are manageable with over-the-counter pain medications, including anti-inflammatory medicines that decrease cranial swelling.

Additionally, a number of secondary headache triggers, such as tension, dehydration, and eye strain, can be avoided proactively.

Migraines and cluster headaches are characterized by their intricate nature, and universally effective treatments for these conditions have yet to be identified.

However, it is fortunate that pharmacologists and neurologists are diligently striving to unravel these perplexing enigmas that burden our thoughts.
