What is a headache?

Headache is defined as pain in the head or upper neck. It is one of the most common locations of pain in the body and has many causes.

How are headaches classified?

Headaches have numerous causes, and in 2007 the International Headache Society agreed upon an updated classification system for headache. Because so many people suffer from headaches, and because treatment is sometimes difficult, the new classification system allows health care practitioners to understand a specific diagnosis more completely to provide better and more effective treatment regimens.

There are three major categories of headaches:


1.primary headaches,


2.secondary headaches, and


3.cranial neuralgias, facial pain, and other headaches

What are primary headaches?

Primary headaches include migraine, tension, and cluster headaches, as well as a variety of other less common types of headache.

Tension headaches are the most common type of primary headache; as many as 90% of adults have had or will have tension headaches. Tension headaches are more common among women than men.

Migraine headaches are the second most common type of primary headache. An estimated 28 million people in the United States (about 12% of the population) will experience migraine headaches. Migraine headaches affect children as well as adults. Before puberty, boys and girls are affected equally by migraine headaches, but after puberty, more women than men are affected. An estimated 6% of men and up to 18% of women will experience a migraine headache.

Cluster headaches are a rare type of primary headache, affecting 0.1% of the population. An estimated 85% of cluster headache sufferers are men. The average age of cluster headache sufferers is 28-30 years of age, although headaches may begin in childhood.

Primary headaches affect quality of life. Some people have occasional headaches that resolve quickly, while others are debilitated. Tension, migraine, and cluster headaches are not life-threatening.


What are secondary headaches?

Secondary headaches are those that are due to an underlying structural problem in the head or neck. There are numerous causes of this type of headache ranging from bleeding in the brain, tumor, or meningitis and encephalitis.
What are cranial neuralgias, facial pain, and other headaches?

Neuralgia means nerve pain (neur= nerve + algia=pain). Cranial neuralgia describes a group of headaches that occur because the nerves in the head and upper neck become inflamed and are the source of the head pain. Facial pain and a variety of other causes for headache are included in this category.


What causes tension headaches?

While tension headaches are the most frequently occurring type of headache, their cause is not known. The most likely cause is contraction of the muscles that cover the skull. When the muscles covering the skull are stressed, they may spasm and cause pain. Common sites include the base of the skull where the trapezius muscles of the neck inserts, the temple where muscles that assist the jaw to move are located, and the forehead.

There is little research to confirm the exact cause of tension headaches. Tension headaches occur because of physical or emotional stress placed on the body. Physical stress that may cause tension headaches include difficult and prolonged manual labor, or sitting at a desk or computer for long periods of time Emotional stress may also cause tension headaches by causing the muscles surrounding the skull to contract.

I like to imagine that I’m a kind, patient person. That I embody calm when confronted with prickly personalities. That their aggravations roll off me like water off a duck’s back. But this delusion is quickly dispelled every time I have a run-in with a difficult person. Take last week: My friend (let’s call her Liz) and I decided to meet at noon for lunch. She’s often late, so I took my time walking over to the cafĂ©. But mid-stroll, I became paranoid that Liz would be punctual for once, so I rushed to be there on the dot. She was nowhere to be seen. I breathed deeply, rationalizing that now I had some coveted alone time. That lasted all of four minutes. At 12:08, I called Liz on her cell, convinced I’d given her the wrong address. She never picked up. Ten minutes later, she showed up with a big smile and zero apology. “Oh, don’t be mad at me. You know I’m always late,” she said. “It’s just part of my personality. Besides, haven’t you enjoyed all the great people watching?" My reaction was less like a duck, more like a rabid dog. The worst part was that my emotional equilibrium had been knocked off-kilter. It took me a good 15 minutes to calm down enough to actually enjoy spending time with my friend. Trying personalities like Liz’s are everywhere — in your home (possibly sharing your bed), at the office, in your book club. They may even be complete strangers. What makes them difficult may be an undisputed character flaw — they’re sycophantic or self-centered or perpetually gloomy — or simply a quirk that rubs you the wrong way. But inevitably, a brush with them leaves you fuming or at least out of sorts. Instead of devising elaborate avoidance schemes or barbed comebacks, you can change your dynamic with these sanity stealers. Use the following strategies to end the emotional tug-of-war, once and for all. Turn the Spotlight on You “You must change how you react to people before you can change how you interact with them,” says Rick Kirschner, N.D., coauthor of Dealing with People You Can’t Stand. That requires some self-examination. People who irritate us usually have something to show us about ourselves. “Ask yourself: How is this person holding up the mirror to me?” suggests Sandra Crowe, author of Since Strangling Isn’t an Option. For example, being around my chronically late friend reminds me how quick-tempered and impatient I can be — not my favorite traits. Reminding myself of this may keep me from bouncing off the walls when I find myself waiting for her yet again.
