You have probably come across the word ‘Headaches‘ when the doctor mention or your friends mention. What do you think is it? Does it feels pain in the region of your head or neck? If you think about it, it’s strange it even exists. A headache is defined as a pain arising from the head or upper neck of the body. The pain originates from the tissues and structures that surround the skull or the brain because the brain itself has no nerves that give rise to the sensation of pain (pain fibers). It really senses you don’t want to do anything even if you want much. It conquerors your head and much like conquerors your body and your environment too. So the thing is “what causes this conqueror to conquer our head and body?” Let’s proceed.
What Causes Primary Headache?
Primary headaches are not symptomatic of an underlying disease, injury, or condition; they are the condition. A primary headache is caused by overactivity of or problems with pain-sensitive structures in your head.
Chemical activity in your brain, the nerves or blood vessels surrounding your skull, or the muscles of your head and neck (or some combination of these factors) can play a role in primary headaches. Some common primary headaches are:
What Causes Secondary Headache?
- Acute sinusitis (sinus infection)
- A brain aneurysm (a bulge in an artery in your brain)
- Brain AVM (arteriovenous malformation) — an abnormal formation of brain blood vessels
- Brain tumor
- Carbon monoxide poisoning
- Chiari malformation (the structural problem at the base of your skull)
- Ear infection (middle ear)
- Encephalitis (brain inflammation)
But let’s take just one common case —a sinus infection—as an example. The sinuses are a system of cavities that spread behind our foreheads, noses, and upper cheeks. When our sinuses are infected, our immune response heats up the area, roasting the bacteria and inflaming the cavities well past their usual size. The engorged sinuses put pressure on the cranial arteries and veins, as well as muscles in the neck and head. Their pain receptors, called nociceptors, trigger in response, cueing the brain to release a flood of neuropeptides that inflame the cranial blood vessels, swelling and heating up the head. This discomfort, paired with hyper-sensitive head muscles, creates the sore, throbbing pain of a headache.
In ancient Greece, headaches were considered as powerful afflictions. Victims prayed for relief from Asclepius, the god of medicine. And if the pain continued, a medical practitioner would perform the best-known remedy— drilling a small hole in the skull to drain supposedly infected blood. This dire technique called trepanation often replaced a headache with a more permanent condition.
