Because headaches are a part of almost all of our lives, people with chronic headaches sometimes don't realize that they may need to see a doctor. They tend to believe, incorrectly, that their headaches are like everyone else's and they will only be "bothering(打扰，麻烦)" the doctor.
"When should somebody seek medical help for headaches? neurologist Seymour Diamond asks rhetorically (提出问题进行探讨). Generally, whenever headaches are associated with neurological signs, such as dizziness(头昏，头晕), weakness in a limb or limbs, vision impairment of any sort—including seeing flashing lights—they warrant(应受) immediate attention. Additionally, Diamond says that you should seek medical attention:
If you suffer from almost daily headaches;
If the headache is a type you've never had before, or there has been a change in the character(特征) of the headache;
If you're losing time from work or activities, or otherwise being prevented from functioning.
Even if your headaches are less dramatic than those described here, if they are a re- al problem to you, you should seek help. It may be that your doctor will be unable to find a physical cause for your discomfort, but that may point you in other directions to find relief. Some headaches, particularly those caused by tension, have a major psycho- logical component that might be relieved through counseling (走向，指导).
