Is This Just a Headache? How to Tell Tension Headaches, Migraines and Warning-Sign Headaches Apart

Doctors divide headaches into two broad groups. Primary headaches, such as tension headaches and migraines, are the main problem themselves. Secondary headaches are a symptom of something else, such as infection, injury, high blood pressure, or medication effects. Most headaches people deal with day to day are primary.

The three you will hear about most:

• Tension-type headache: the most common type, usually a dull, band-like pressure on both sides of the head
• Migraine: often a throbbing pain on one side, with nausea and sensitivity to light or sound; some people see visual changes called aura first
• Cluster headache: rare but severe, with intense pain around one eye, tearing, and a stuffy or runny nostril, often at the same time each day during a cluster period

For deeper patient-friendly background, see the MedlinePlus headache overview. Remember that this table is a guide. Some people have overlapping features, and only a clinician can sort out a pattern that does not fit neatly.

Triggers are things that make a headache more likely. The graph below shows how often people commonly report different triggers. It is an illustrative guide for self-tracking, not a measured statistic, and your own triggers may differ.

Dehydration is an easy trigger to fix. Our guide on dehydration warning signs includes a urine-color chart, and our article on sleep and your health covers sleep habits that help.

At the first sign of an ordinary headache, try this order:

1. Pause and drink a glass of water, since mild dehydration is a common contributor.
2. Eat something if you have gone several hours without a meal.
3. Rest in a quiet, dim room if light or noise makes the pain worse.
4. Apply a cool cloth to the forehead or neck, or a warm compress if the muscles feel tight.
5. Gently stretch the neck and shoulders and relax your jaw.
6. If you use an over-the-counter pain reliever, follow the label and check with a pharmacist or clinician if you have stomach, kidney, liver, or heart conditions or take other medicines.
7. Write down the date, time, possible trigger, and what helped, so you can spot patterns.

Taking pain relievers too often can lead to medication-overuse headache, where the medicine itself keeps the headaches coming back. As a general guide, if you find yourself needing pain relievers on most days of the week, or on more than about two or three days per week, speak with a clinician. Do not stop prescription medicines on your own.

Most headaches are harmless, but a few patterns need immediate attention. Call 911 or go to the emergency room if you have any of the following.

High blood pressure can contribute to headaches in some situations. Our guide to high blood pressure explains what the numbers mean and when to act.

A thorough visit for recurring headaches usually involves:

1. A detailed history: when headaches started, how often, how long they last, and what you feel before and during them
2. A review of medicines, caffeine, sleep, stress, and family history
3. A physical and neurological exam, including blood pressure and eye and nerve checks
4. Blood tests or imaging only when the history or exam suggests they are needed
5. A treatment plan that may include lifestyle changes, medicines for acute attacks, preventive medicine, or referral to a neurologist

Routine blood tests can sometimes rule out contributing factors such as anemia or thyroid problems. Learn more in our article on common blood tests, or explore primary care and diagnostic testing at City Prime Care.

These habits reduce headaches for many people:

• Keep a headache diary for at least a month
• Sleep and wake at consistent times
• Stay hydrated and eat regular meals
• Move your body most days; gentle aerobic exercise helps many people
• Limit alcohol and keep caffeine steady
• Take screen breaks and check your vision if you have frequent eye strain
• Practice stress-management techniques such as breathing exercises or short walks

Understanding the type, trigger, and pattern of your headaches puts you in control. Treat ordinary headaches with rest, fluids, and routine, but never ignore sudden, severe, or unusual symptoms.
