A headache is pain anywhere in the region of the head or upper neck. According to the National Headache Foundation, more than 15% of North Americans suffer from chronic, recurring headache. Approximately 90% of people will suffer from at least one headache in their lifetime. About 20 percent of children and adolescents also have significant headaches. In fact, headaches are the most common cause of absenteeism from work and school.
There are a number of different classification systems for headaches; the best-recognized is that of the International Headache Society. The most common types of headache are “primary headaches”, such as tension-type headache and migraine. Most headaches are NOT caused by any serious underlying problem.
What causes headaches?
The brain tissue itself is not sensitive to pain because it lacks pain receptors. Rather, the pain is caused by irritation of the pain-sensitive structures around the brain. Tissues around the brain that have pain-sensitive structures and can be responsible for headaches are the cranium (the skull bone), muscles, nerves, arteries and veins, connective tissues, eyes, ears, sinuses and mucous membranes.
How can headaches be treated?
The best treatment approach for headaches is dependent upon the type of headache a person is suffering from. The International Headache Society has differentiated over 100 different types of headaches, so correct diagnosis can sometimes be difficult. Most headaches are tension-type or migraine headaches, or are secondary to muscle or joint irritation in the neck. Fortunately for headache sufferers, these types of headaches are usually not dangerous and can often be treated.
A 2011 review found that chiropractic manipulation, exercise, massage and relaxation might be as effective as some commonly used medications for the prevention of migraine headaches. For headaches that are caused by joint or muscle irritation in the neck (cervicogenic headache), manual therapies like chiropractic can be an effective treatment.
High-quality research has found that Acupuncture can offer significant relief of both tension headaches and migraine headaches.-
