Headache
Tension-type, migraine, cluster, and the dangerous patterns
Most headaches are tension-type or migraine, and they are miserable but not dangerous. The clinical job is sorting the common patterns from the rare dangerous ones. A thunderclap headache that peaks within a minute, headache with fever and a stiff neck, or headache with weakness, confusion, or trouble speaking is an emergency. A dull band-like ache after a long day is not.
Get help now
Call 911 now for:
- a thunderclap headache: maximum pain within a minute, often "the worst headache of my life"
- headache with stroke signs: face drooping, one-sided weakness, slurred speech
- headache with fever, a stiff neck you cannot bend toward your chest, and confusion or a rash that does not blanch under pressure
- a severe headache after a head injury, especially with vomiting or drowsiness
Those are the bleeding, stroke, and meningitis patterns, where minutes matter. Also get same-day care for a headache that is new or clearly different after age 50, one that steadily worsens over days to weeks, wakes you at night, or is worse lying down, or a severe headache during pregnancy or the first weeks after delivery.
What to do right now
- For an ordinary headache: water, food if you skipped a meal, a screen break, and a normal dose of acetaminophen or ibuprofen.
- If it is your usual migraine pattern: take your acute medicine early, and get to a dark, quiet room.
- Do not take painkillers on more than about 10 to 15 days a month; that habit can itself cause a daily headache.
- If this headache is sudden, the worst of your life, or comes with weakness, confusion, trouble speaking, fever and a stiff neck, stop reading and call 911.
The most common types
- Tension-type: dull, tight, band-like pressure on both sides. Mild to moderate. You can still function.
- Migraine: one-sided, throbbing, moderate to severe, worse with movement, usually with nausea and light or sound sensitivity. Some people get visual aura first.
- Cluster: rare and excruciating, around one eye, with tearing and a stuffy nose on that side, in attacks that cluster over weeks.
- Medication-overuse: a daily headache caused by taking painkillers too often. The fix is tapering off them, not taking more.
Triggers and causes
Everyday headaches are usually driven by ordinary things: short or irregular sleep, skipped meals, dehydration, caffeine withdrawal, alcohol the night before, stress, long screen stretches, and teeth grinding overnight. Morning headaches have their own short list: poor sleep, snoring or sleep apnea (a dull morning headache that fades within hours), medication overuse, weekend caffeine withdrawal, and grinding. Migraine adds triggers like hormonal shifts, weather changes, and specific foods, and keeping a simple trigger diary for a few weeks usually finds the pattern. A morning headache that is severe, progressively worsening over weeks, or comes with vomiting or vision changes is different and needs a doctor promptly, because that combination can signal raised pressure in the head.
How a clinician checks it
Headache diagnosis is almost entirely story-based: where it is, how it starts, how fast it peaks, what it feels like, what comes with it, and how often. The clinician is sorting your pattern against the common types and checking for the red-flag features that change the plan. An exam checks neurological function (strength, speech, vision, reflexes, neck stiffness). Imaging is not routine; it is reserved for red-flag patterns, a new headache later in life, a headache after injury, or one that keeps worsening. That is why the history you give matters more than any single test.
Treatment
- Tension-type: ordinary doses of acetaminophen or ibuprofen, water, food if you skipped a meal, and a screen break.
- Migraine: an acute medicine taken early in the attack (over-the-counter painkillers for mild attacks, triptans from a clinician for moderate to severe ones), plus prevention when attacks are frequent, which ranges from sleep, meal, and trigger regularity to daily preventive medicines.
- Cluster: needs a clinician; the real treatments (high-flow oxygen, specific prescriptions) are not over the counter.
- All types: painkillers on more than about 10 to 15 days a month can themselves cause a daily headache.
Can telehealth help?
Text or telehealth works well for the middle ground: recurrent tension headaches, known migraines that need a prescription refill or a better acute plan, and sorting out whether your pattern sounds like migraine, tension, or medication overuse. A clinician can review the history, adjust treatment, and send prescriptions remotely, because headache diagnosis is almost entirely story-based. What telehealth cannot do is the emergency work: a thunderclap headache, stroke signs, or fever with a stiff neck need an emergency room and imaging, not a chat.
How long it lasts
A tension headache usually fades within hours. A migraine attack typically runs 4 to 72 hours untreated, shorter when the acute medicine goes in early. Cluster attacks are brief but repeat daily for weeks. The pattern over time matters more than any single episode: headaches that are stable and familiar are managed; headaches that are new, changing, or steadily worsening get checked.
Prevention
- Keep sleep, meals, and caffeine on a steady schedule; irregularity is the most common driver.
- Track triggers for a few weeks if attacks repeat.
- Stay under the painkiller threshold: no more than 10 to 15 days a month.
- Frequent migraines are worth a prevention plan from a clinician, not just stronger acute medicine.
