Chapter 1
What it looks like
Much of what people simply call a headache is this one. Tension-type headache is the most prevalent neurological disorder worldwide: recurrent, mild to moderate, on both sides, with a pressing or tightening quality, and not made worse by routine activity such as walking or climbing stairs (Ashina 2021).
That last feature is one of the keys to telling it from migraine, which is often one-sided and throbbing, worse with activity, and may come with nausea and sensitivity to light. The Migraine story covers its mechanism and how to tell similar-looking headaches apart.
Diagnosis rests on the history of the headache and on ruling out other causes; no lab test or scan directly proves that you have tension-type headache (Ashina 2021). That is why the checklist in the chapter When to see a doctor matters more than any other chapter here. The most urgent item on it: a severe headache that starts suddenly and hits its peak fast is not this kind of headache — go to emergency care now.

Chapter 2
Where the pain starts, and how it turns chronic
Because the name contains tension, many people assume it is directly caused by mental stress or tight muscles. In fact its biological basis remains unresolved (Ashina 2021).
The likelier picture has two layers. First, the pain itself in each episode probably starts peripherally, in tissues outside the brain and spinal cord. Second, the shift from occasional episodes to a near-daily chronic form may involve central sensitization: the pain-processing circuits are tuned to be more sensitive, so the same input is amplified into stronger pain (Ashina 2021).
How the central nervous system turns pain up is explained in full in the story How Pain Is Made. What to keep from this chapter: episodic and chronic headache differ not only in how often they happen, but possibly in which layer of mechanism is at work. The practical step that follows — getting frequent episodes under control early — is a reasonable inference that has not yet been tested in dedicated trials.

Chapter 3
Painkillers: they work, but not too often
For an occasional tension-type headache, simple painkillers (simple analgesics) have evidence-based effectiveness and are widely regarded as the first-line treatment for an acute attack (Ashina 2021).
The problem is frequency. The more frequent the headaches, the more painkillers get taken — and painkillers taken too often can themselves make headaches more frequent. That is medication-overuse headache. It is on the warning list for secondary headaches: painkiller overuse, or a new drug started around the time the headache began, is one of the signals that warrants a doctor's look (Do 2019). The Migraine story gives the concrete threshold in days per month, and it applies to tension-type headache too.
If attacks are already frequent, or painkillers do not work, are poorly tolerated or cannot be taken, the step to consider is prevention: under a doctor's guidance there are several medicines and some non-drug therapies to choose from (Ashina 2021). This site does not give specific drugs or doses; decide that step together with a doctor.

How much evidence for non-drug options
Among non-drug options, acupuncture shows most clearly how to read the evidence. The 2016 Cochrane review (12 trials, 2,349 people) splits the evidence into three parts, and they have to be read separately:
Versus routine care or acute treatment only: in two large trials, far more people in the acupuncture groups cut their headache frequency by at least half (48% vs 19% in one, 45% vs 4% in the other). But neither trial was blinded, and no effects beyond 4 months were studied.Versus sham acupuncture (a control that needles off the acupoints or does not really penetrate): a much smaller gap, 51% vs 43% ( 1.3; the review rated the certainty of this comparison as moderate).Versus physiotherapy, massage or exercise: no trial found acupuncture better, and some results slightly favored the comparison treatment.
The authors conclude that acupuncture appears effective for frequent episodic or chronic tension-type headache, but that more comparisons with other treatments are needed. Read the numbers this way: much better than routine care, only a little better than sham, and no advantage over physiotherapy or exercise. Why it works is a question the review does not answer.

When to see a doctor
Tension-type headache is a diagnosis of exclusion, so what matters most is knowing which headaches must not be treated as one. From the SNNOOP10 list that neurologists use to screen for secondary headache (a headache caused by another condition), these signals mean you should see a doctor in person promptly (Do 2019):
a severe headache of sudden, abrupt onset — go to emergency care nowfever or other whole-body symptomsneurological signs: weakness or numbness on one side, slurred speech, double vision, reduced consciousnessa first headache after age 65, or a change in pattern, or a recent new headachea headache clearly made worse or better by posture, or brought on by coughing, sneezing or exertiona headache that started after a head injury, or a new headache in pregnancy or after childbirtha new headache in someone with a history of cancer or a weakened immune systema headache that keeps getting worse, or comes with painkiller overuse
This list was compiled by experts from clinical experience, and its accuracy still lacks validation in prospective studies (Do 2019). So the way to use it is see a doctor one time too many, not to score yourself item by item and wait until enough boxes are ticked.
