4．Almost everyone suffers from a headache sometimes．But some people suffer from repeated，frequent headaches．
What is headache？What causes it？What can be done about a headache？What research is being done on headaches？
The dictionary defines （下定義） headache simply as"a pain in the head．"What most people mean by headache is a pain which lasts several minutes or hours．It covers the whole head，or one side of it，or perhaps the front or the back of the head．To add to the confusion （困惑） about a definition，some people call tight feeling in the head a headache．
A headache is important because it can be the first warning of a serious condition which probably could be controlled if discovered early．If a person removes the warning，day after day，with a pain-killer，he may pass the point of easy control．
The professional name for covering up a symptom （癥狀） is"masking"（遮蔽）．A headache expert once said，"Masking symptoms is not the best way of treatment．"He compared taking a pain-killer for a headache before a cause is known with taking iron pills for anemia （貧血癥） while bleeding continues undiscovered．He added，"Sometimes it is wiser to stand still than to advance in darkness．"
A headache is important also because it affects normal，happy living．The employee with a headache does less work．In a flash of temper he may upset （使心煩意亂） his workmates or customers，causing a direct or indirect loss to his organization．The mother with a headache suffers and disturbs the family．She upsets her husband and children．
