Headaches affect a large portion of adults globally each year, and with over 150 types identified, they can be difficult to categorize. Many headache disorders respond well to specialized treatment, but accurate diagnosis is essential.
Chronic or Recurring Headaches
Occasional headaches are normal, but frequent head pain may indicate a headache disorder that can worsen over time. Common chronic headache disorders include:
- Migraines
- Tension headaches
- Hemicrania continua
- Trigeminal neuralgia
- Occipital headaches
Seek care if headaches increase in frequency or severity, or fail to improve with over-the-counter medications.
Sudden and Intense Pain
Headache location and severity can provide diagnostic clues. Migraines often cause throbbing on one side of the head with sensitivity to sound, light, and smell. Occipital headaches typically originate at the nape of the neck.
A sudden, severe headache — the worst you've had in your whole life — may indicate a leaking brain aneurysm. Seek emergency care immediately in such cases.
Additional Symptoms to Watch For
Headaches alongside fever, stiff neck, or other neurological signs may point to serious underlying conditions such as meningitis. Warning symptoms include:
- Ache behind or around the eye
- Blurry vision
- Unexplained nausea or vomiting
- Temple pain in those over 50
- Numbness, weakness, or paralysis on one side
- Confusion or altered mental state
- Difficulty speaking or walking
- Fainting
These symptoms are especially urgent when paired with sudden, intense head pain. Professional evaluation is strongly recommended.
