There are no pain receptors in the brain, so what hurts us with a headache?

Even the tension is The most common triggers for headaches Commonly, not sleeping enough hours, skipping meals, or drinking alcohol are added to it.

Almost everyone gets a headache from time to time. It may be caused by a stiff neck after staring at a computer screen all day or pressing on both sides of the head, or even facial pain from a sinus infection or after inhaling a lot of pollen on a beautiful spring day.

All of these and other factors contribute to the infection HeadacheBut what actually causes headache pain?

Reasons Normal headache

When a headache starts, the mind or brain doesn’t hurt, even if that is where you feel the pain. So what hurts us when a headache?

The reason is that the brain does not contain pain receptors, which is why surgeons can stimulate the brains of fully conscious people and ask them what they are going through, a technique that enabled researchers to start mapping the brain.

On the other hand, the rest of the head is full of pain receptors or nociceptors, or very small nerve fibers that send back to the brain a message that something potentially harmful is happening.

Pain receptors are found in the head and neck, inside and outside the skull, and in the covering of the brain. Painful fibers are also found in the veins and nerves.

So what causes the pain fibers to be irritated? It’s often the same thing that triggers back pain after cleaning a garage or home, or knee pain after a run: sore.

In turn, Head of the Department of Neurology at Vanderbilt University Medical Center Dane Chetkovitch said: “When your neck muscles are tight for a very long time while staring at a computer screen, or when you are generally tense and your muscles tight, the resulting pain is inflammation of the muscles, so you get stiff neck. Tension headache in the skull. “

If the headache was caused by an infection, a similar mechanism would be used, for example sinusitis, which causes inflammation that irritates the pain fibers in the lining of the sinuses.

If it is a bacterial infection, toxins secreted by the bacteria may irritate these fibers.

But it all comes down to something that disturbs the pain fibers, the mind interprets that discomfort as pain, and you call it a headache.


In addition to tension headaches, many people suffer from the most common type of headache of them all: migraine.

And theMigraines In fact, it breaks most of the headache rules, and as the second most common type of headache, migraine can cause all kinds of strange and extremely tiring symptoms, in addition to headache.

Its consequences include dizziness, nausea, and visual disturbances such as blurry vision and hypersensitivity to light, sound and smell.

Sometimes migraines do not cause a headache, but rather other symptoms that are often called “silent migraine”, according to what was published entirely Harvard Medical.

Some of the mechanisms are the same for migraines as for other headaches, Cikovic explains for Magazine Discover: “With migraine, there is inflammation in the meninges or blood vessels inside or outside the skull, but the difference is that this inflammation is not caused by overuse.”

He added, “It is the result of a combination of genetic and environmental changes that cause pain for some vulnerable people.”

It might start with some neck strain pain from strenuous work, and then end up with a migraine / istock attack

What hurts us when headaches?

But then again, what is really causing the pain, or in the case of a migraine, all these strange symptoms?

Sylvia Lucas, an honorary clinical professor of neurology at the University of Washington Medical Center, says there are still many mysteries related to migraines.

But it summed up this way: The membranes that line the brain are filled with nerves, and these nerves pour out a variety of chemicals that can activate pain receptors.

When this happens, the nerves send a message to the brain and the brain reads the message “pain,” or more specifically, “migraine.”

But as with most things related to migraines, the story is not so simple. In people with a genetic predisposition, tension headaches can develop into a migraine.

“It’s very strange, it starts with stiffness in the neck, but then it activates the brain, and the brain rotates and causes inflammation in the blood vessels inside the head,” says Chetkovitch.

So you might start with some neck pain from strenuous work, and then end up with a migraine attack.

Lucas explains that a migraine is a dysfunction of the ion channel, meaning that the electrical signals in the brain do not always work properly, and that can be a real headache.
