Headaches

Most headaches are not serious and get better with rest, fluids, and over-the-counter pain relief. Some headaches are warning signs that need emergency care.

Call 911 right away if:
  • The worst headache of your life, or a sudden, severe headache that comes on like a thunderclap
  • A headache with confusion, fainting, trouble seeing, speaking, or walking, or weakness or numbness on one side of the body
  • A headache with a high fever and stiff neck
  • A headache after a blow to the head
  • A headache with a seizure, or with vomiting that isn’t clearly from a stomach bug or hangover
  • A headache while a carbon monoxide alarm is sounding, or when others in the home feel sick too

What to do

  1. Rest in a quiet, dark room if light or noise bothers you.
  2. Drink water. Not drinking enough can trigger headaches.
  3. Use a cool or warm compress on your forehead or the back of your neck.
  4. Try an over-the-counter pain reliever like acetaminophen or ibuprofen. Follow the package directions. Taking it early often works best.
  5. Eat something if you’ve skipped a meal.
  6. Relax tight muscles by stretching your neck and shoulders, or try slow, deep breathing.

Prevention

  • Get regular sleep, eat regular meals, and drink enough water.
  • Limit alcohol, and keep caffeine steady (suddenly cutting back can cause headaches).
  • Take breaks from screens, and manage stress.
  • Keep a headache diary to spot triggers like certain foods, poor sleep, or stress.

Avoid

  • Using pain medicine too often (more than a couple of days a week) can lead to more headaches. Talk with a doctor if you need it often.
  • Don’t give aspirin to children or teens.
See a doctor or go to urgent care if:
  • Headaches happen more often or are worse than usual
  • Headaches don’t get better with over-the-counter medicine, or you need pain medicine for headaches more than a couple of days a week
  • Headaches keep you from working, sleeping, or doing normal activities
  • A new kind of headache starts after age 50, or you are pregnant or have a weak immune system
  • Headaches wake you up or get worse when you cough, strain, or bend over
