When to See a Doctor
When Headaches Attack

Bad Headaches?
Your Doctor Can Help.
Sometimes—in fact most times—a headache is just that: a headache. But a headache can also be a sign that something else is wrong with the body. Headaches could be a sign of:
- Infections
- Head injuries
- Eye disease
- Hormonal imbalances
- A brain tumor
- Drugs and toxins
We’re not trying to scare you, but it is headaches can be serious. Again, if you get a mild headache every now and then--it's probably just a simple headache. But how can you tell the difference? How can you tell when a headache is a sign of something more serious and how do you know when you should see a doctor?
If your headache meets any of the following criteria, you should consider consulting a health-care professional to find out if the cause might be something serious:
| Visit Your Doctor If... |
| The headache persists for more than a day |
| The headache changes or consistently gets worse, even after you take medicine |
| The headache starts as, or changes to become, a type of headache you’ve never experienced before |
| The headache comes on very suddenly with no apparent cause |
| The headache follows a blow to the head |
| The headache wakes you up at night |
| The headache involves convulsions or loss of consciousness |
| And, in general, if the severity and/or frequency of the headache is such that it interferes with day-to-day living |
Now let's explore specific types of headaches.
