Blew research is giving us more【C2】______about two common types of headaches: tension headaches and migraine headaches. The most painful【C3】______are migraines, which【C4】______about eight to ten percent of the time and are【C5】______as a very sharp, throbbing pain. Most heada ches,【C6】______, are tension headaches.

These headaches are caused by the tightening of the muscles of the head and neck, which【C9】______causes the blood vessels to narrow, making it difficult for the brain to receive the oxygen(water, nutrition, blood) it needs. This is what causes the pain. Migraines,【C10】______, result from the blood vessels in the brain enlarging, causing swelling in the brain. This swelling results in terrible pain. The headache may last for a day or two and【C11】______the individual sick and weak. Migraines are apparently【C12】______, because several individuals in the same family usually have them. Doctors believe that the brains of these individuals【C13】______in unusual ways to small problems, like failing a test or eating unwisely.【C14】______there are warning【C15】______before a migraine occurs, such as spots appearing before the eyes or a sick feeling in the【C16】______. If the person takes medicine or caffeine as soon as he or she begins to feel the headache coming【C17】______, it can be【C18】______.
