The core difference: location, sensation, and what makes it worse

A tension headache feels like a band of pressure around your head—usually mild to moderate, steady, and the same on both sides. It does not throb. You can usually still work or function, though you may feel irritable or have trouble concentrating. Tension headaches often come from muscle tightness in your neck, scalp, or jaw, and they typically last 30 minutes to several hours.

A migraine is a neurological event, not just a bad headache. It usually throbs on one side of your head and ranges from moderate to severe—often bad enough that you need to stop what you are doing. Migraines come with other symptoms: nausea, sensitivity to light or sound, or sometimes a visual warning called an aura (flashing lights, zigzag lines, or blind spots that appear 20 to 60 minutes before the headache starts). A migraine attack typically lasts 4 to 72 hours.

The practical difference matters because the two respond to different treatments. Over-the-counter pain relievers work for most tension headaches. Migraines often need prescription medication or specific over-the-counter drugs designed for migraine, and they respond better to treatment started early in the attack.

Key Takeaways

  • Tension headaches are bilateral (both sides), steady pressure; migraines are usually one-sided, throbbing, and often come with nausea or light sensitivity.
  • Migraines may include an aura—visual disturbances like flashing lights or zigzag lines appearing before the headache starts.
  • Tension headaches last 30 minutes to a few hours; migraines typically last 4 to 72 hours.
  • Physical triggers for tension headaches include muscle tightness and stress; migraine triggers vary widely by person and may include hormones, certain foods, sleep changes, or weather.
  • See a doctor if headaches change in pattern, occur more than four days a month, or are accompanied by fever, vision changes, confusion, or weakness.

What triggers each type

Tension headaches usually follow stress, poor posture, jaw clenching, or muscle tension in your neck and shoulders. They are more common on days when you are anxious, working at a desk for hours without moving, or grinding your teeth at night. Caffeine withdrawal can also trigger one. Once you identify the trigger—usually obvious in hindsight—you can often prevent the next one by addressing the underlying tension.

Migraine triggers are more individual and harder to predict. Common ones include hormonal changes (many women notice migraines around their menstrual cycle), skipped meals, dehydration, too much or too little sleep, bright lights, loud noises, strong smells, weather changes, and certain foods (chocolate, aged cheese, processed meats, and foods with MSG are frequently reported). Stress itself does not always trigger a migraine—sometimes it is the relief from stress that does, which is why some people get migraines on the first day of vacation.

Keeping a headache diary for a few weeks can help you spot your own patterns. Write down when the headache started, what you were doing, what you ate, your sleep the night before, and your stress level. Over time, patterns emerge that your doctor can use to help you prevent future attacks.

How to recognize an aura and what it means

An aura is a warning sign that a migraine is coming. It appears 20 to 60 minutes before the headache pain starts and typically lasts 20 to 30 minutes. The most common auras are visual: flashing lights, zigzag lines, blind spots, or temporary blurring in part of your vision. Some people experience other auras instead—tingling in your arm or face, difficulty speaking, or temporary weakness on one side of your body.

If you have an aura, you have time to take migraine medication before the pain arrives, which often stops the attack or makes it much milder. This is why recognizing an aura matters: it is your window to intervene early. Auras without a headache following them are rare but can happen; if you suddenly develop new visual symptoms or weakness, see a doctor to rule out other causes.

Not everyone with migraines has an aura—in fact, most do not. If you never have warning symptoms, that does not mean your migraines are not real; it just means you have migraine without aura, which is the more common type.

Over-the-counter options and when they work

For tension headaches, standard pain relievers usually work well: ibuprofen (Advil, Motrin), naproxen (Aleve), or acetaminophen (Tylenol). Take them as soon as the headache starts, and most tension headaches improve within an hour. Applying heat to your neck or shoulders, stretching, or taking a break from your screen can speed relief.

For migraines, regular pain relievers are less reliable. However, over-the-counter migraine-specific products exist: ibuprofen combined with caffeine (Excedrin Migraine) works for some people, especially if taken early. Naproxen sodium (Aleve) is also used for migraine. The key is timing—these work better if you take them as soon as you feel a migraine starting, ideally during an aura if you have one.

If over-the-counter options do not stop your migraines or you need them more than twice a month, talk to a doctor. Prescription migraine medications (triptans like sumatriptan, or newer options like CGRP inhibitors) are far more effective for many people and work through different mechanisms than regular pain relievers. Your doctor can help you find what works for your specific pattern.

When to see a doctor about your headaches

See a doctor if your headaches change—if they become more frequent, more severe, or different in character than before. Also see a doctor if headaches occur more than four days a month, because that pattern suggests you may benefit from preventive treatment rather than just treating each one as it happens.

Seek urgent medical attention if a headache is accompanied by fever, stiff neck, confusion, vision changes, weakness, numbness, difficulty speaking, or loss of consciousness. These can signal a serious condition like meningitis, stroke, or other neurological problems. Also seek urgent care if you have the worst headache of your life, especially if it came on suddenly—this is a classic sign of a subarachnoid hemorrhage, a medical emergency.

If you have a history of migraines and develop a headache that feels different from your usual ones, get it checked. Doctors are trained to distinguish migraine from other causes, and the difference matters for treatment. Keeping that headache diary you started will help your doctor understand your pattern and recommend the right approach.

Preventing migraines and tension headaches

For tension headaches, prevention focuses on reducing muscle tension: manage stress through exercise or relaxation techniques, take breaks from screens to stretch your neck, maintain good posture, and address jaw clenching if you grind your teeth at night (a dentist can fit you for a night guard). These changes prevent many tension headaches before they start.

For migraines, prevention is more complex because triggers vary. Once you identify your triggers through a headache diary, you can avoid them when possible—staying hydrated, eating regular meals, keeping a consistent sleep schedule, and managing stress. Some people find that regular aerobic exercise reduces migraine frequency. If you have frequent migraines (four or more a month), your doctor may recommend preventive medication—drugs taken daily to reduce how often migraines occur, not to treat them once they start. These include beta-blockers, certain antidepressants, anticonvulsants, or newer CGRP inhibitors.

Preventive medication takes weeks to show effect, so it is not a quick fix. But for people with frequent migraines, it can cut the number of attacks in half or more, which significantly improves quality of life.

Living with chronic headaches: tracking and communication

If you have frequent headaches of either type, a headache diary becomes your most useful tool. Record the date, time of day, severity (on a scale of 1 to 10), location, duration, associated symptoms, what you were doing when it started, what you ate and drank, your sleep the night before, your stress level, and what you took for it and whether it helped. After four to eight weeks, patterns emerge that neither you nor your doctor could spot otherwise.

Share this diary with your doctor at your appointment. It gives them concrete information to work with instead of relying on memory, which is often unreliable for recurring events. It also helps your doctor distinguish between tension headaches and migraines if you experience both, and it shows whether your current treatment is actually working or whether you need to try something different.

Tell your doctor about any headache that worries you, even if it seems minor. Doctors expect these questions and would rather rule things out than have you suffer in silence. The goal is not just to treat headaches when they happen, but to understand your pattern well enough to prevent them or catch them early.

Frequently Asked Questions

Can stress cause both tension headaches and migraines?

Stress commonly triggers tension headaches directly through muscle tightness. For migraines, stress itself is less often the trigger than the relief from stress—many people get migraines on the first day of vacation or after a deadline passes. Some people do have stress-triggered migraines, but the pattern varies by person.

Is a migraine with aura more serious than one without?

Migraine with aura and migraine without aura are both common and usually not dangerous. However, if you have migraine with aura and also take certain hormonal contraceptives, or if you smoke, your doctor may discuss additional considerations with you because of a small increased stroke risk. This is a conversation to have with your doctor, not a reason to panic.

Can you have both tension headaches and migraines?

Yes. Some people experience both types at different times. A tension headache might happen on a stressful workday, while a migraine might hit a few days later triggered by something else entirely. Your headache diary will help you and your doctor tell them apart and treat each appropriately.

Why do migraines sometimes run in families?

Migraines have a genetic component—if one or both of your parents have migraines, your risk is higher. This does not mean you will definitely have them, but it does mean your nervous system may be wired in a way that makes migraines more likely. Tension headaches are less strongly hereditary and more tied to stress and muscle tension.

What should I do if over-the-counter migraine medication stops working?

This can happen because your body adapts to the medication, or because your migraine pattern has changed. Do not simply take higher doses. Instead, see your doctor. They can switch you to a different medication, recommend prescription options, or explore whether preventive treatment would help. Your doctor has many tools available beyond what you can buy over the counter.
