FEATURED BOOKS ON HEADACHES FROM BARNES & NOBLE.COM: WHAT IS A HEADACHE?
Headache is pain in the head from any cause. Headaches are one of the most common types of pain. In fact, in the United States, 7 out of 10 people report having at least one headache each year. The pain may occur all over the head or in one part of the head, such as the front of the head. The pain can also move to different parts of the head. Headache pain can be on the surface of the head or deep in the head. The pain can be sharp, throbbing, constant, and/or dull. Most headaches last for a few hours but some can last for weeks. Headaches are very rarely a sign of a serious disorder, but sometimes they are (see below) and require urgent medical attention.
WHAT CAUSES HEADACHES?
There are many possible causes of headache. Headache pain comes from outside of the brain. Many people do not know that the brain does not have any sensory nerves that register pain. Rather, the pain from a headache comes from the stretching of, or tightening in, the following structures:
The most common cause of headache is stress. This stress can be due to many factors such as nervousness, hunger, changes in weather, exposure to strong sunlight, poor positioning of the body, loud noise, being in a stuffy environment, traveling too much, or sleeping too much. Waking up after drinking too much alcohol can also lead to headaches. Drugs such as nicotine (present in cigarettes) and caffeine (present in many sodas, teas, and coffees) can cause headaches. Eating something unusual can also lead to headaches, as can reactions to certain foods and beverages. For example, some people can develop migraine headaches (described in the next section) by eating chocolate, cheese, or drinking red wine.
Substances that are added to foods such as food colorings, sugars, and salts, can also cause headaches. Toothaches, ear infection, head injury, inflammation of air-filled openings in the bones surrounding the nose (known as facial sinuses), and cervical osteoarthritis can also cause headaches. Cervical osteoarthritis is a painful, worsening condition that affects joints between bones in the neck. Disturbances of a nerve in the head or neck can also cause a headache. Headache pain is not limited to coming from any one nerve.
There are several rare causes of headaches, such as high blood pressure and brain tumors. Tumors are tissues that grow more rapidly than normal. Headaches can also be caused by aneurysms, which is a weakening of the wall of a blood vesselm, causing it to expand like a balloon, sometimes leading it to burst. Increased pressure in the skull can also cause headaches. Headaches can be caused by temporal arteritis, which is an inflammation of arteries in the brain and scalp. Arteries are blood vessels that carry blood away from the heart. Temporal arteritis is suspected in elderly people when the scalp is painful to the touch.
Meningitis, which is an inflammation of the meninges (the three outer coverings of the brain) can lead to headaches as well. A buildup of blood (known as a subarachnoid hemorrhage) between the first two inner layers of meninges that cover the brain can cause headaches. This buildup of blood can be due to damage from a traumatic accident, such as a car accident.
ARE THERE DIFFERENT TYPES OF HEADACHES?
A more painful and continuous type of headache are migraine headaches and cluster headaches. Migraine headaches are so painful that they prevent people who experience them from doing anything. Visual difficulties and/or stomach problems occur before and/or during a migraine headache. Cluster headaches cause intense pain behind one eye. This pain can wake someone up during the night for weeks or months. Neither migraine headaches nor cluster headaches indicate that a worsening disorder is present. ARE THERE OTHER SIGNS AND SYMPTOMS THAT OCCUR ALONG WITH HEADACHES?
Yes. Headaches can be accompanied by other signs and symptoms such as feeling sick to one's stomach (nausea), vomiting, disturbances of vision (such as blurry vision), and/or disturbances of sensation (such as weakness of an arm or leg). Other danger signs include drowsiness, confusion, and loss of consciousness. If these symptoms occur along with a headache, you should seek immediate medical attention.
HOW DO I KNOW WHAT IS CAUSING MY HEADACHE?
We at MedFriendly have compiled a list of indicators that may suggest the particular causes of a headache. Please keep in mind that these are possibilities and that you should consult your doctor for more information. You should also consult your doctor if your symptoms do not match the patterns described on the following list:
WHAT IF MY HEADACHES DON'T GO AWAY?
If your headaches do not go away within 2 hours, reoccur several times a week, are accompanied by other symptoms (see above), or do not respond to self-help treatments (described below), you should contact your doctor immediately to determine the cause and plan for treatment. The doctor will ask where the pain is, what the pain is like, and when the pain occurs. The doctor will do a general physical examination and should examine the head and neck. If the doctor believes that the cause may be something serious, such as a brain tumor, he/she may ask for special tests to be done that produce pictures of the bones of the head and the brain. Two of the most commonly used tests to do this are a Computerized Axial Tomography (CT) scan and a magnetic resonance imaging (MRI) scan. An MRI scan produces clearer pictures but is more expensive.
HOW ARE HEADACHES TREATED?
Preventing headaches is the most important issue to focus on, since many headaches are caused by things that can be easily avoided. This is especially true if the person knows what is causing the headache. See above for a section on causes of headaches. If a headache has started, and it is not a migraine or cluster headache (see above), the following steps should help relieve the headache:
Migraines and cluster headaches are usually treated with medication.
WHO GETS MORE HEADACHES, MALES OR FEMALES?
Headaches are more common in females.
WHAT AGE DO PEOPLE USUALLY GET HEADACHES?
Headaches are more common in people over age 20.
WHAT ELSE IS A HEADACHE KNOWN AS?
Headache is also known as cephalalgia, cephalodynia, encephalalgia, and encephalodynia.
WHAT IS THE ORIGIN OF THE TERM, HEADACHE?
Headache comes from the Anglo Saxon word "heafod" meaning "headache," and the Old English word, "acan" meaning "to hurt." Put the two words together and you have "to hurt head."
Yes. There are many different types of headaches. Some headaches are normal responses to something that is bothering the body, such as hunger. These types of headaches usually go away in a few hours and leave no after affects. Another type of headache is a tension headache, which is caused by tightening of the muscles in the neck, face, and scalp. The tightening of these muscles are caused by stress or positioning the body poorly.
ARE THERE ANY GOOD WEBSITES ON HEADACHES?
Yes. Check out the National Headache Foundation and the American Headache Society.
