THE CONDITION · TENSION-TYPE
Tension-type headache is a pressing or tightening pain on both sides of the head. It is mild to moderate. Climbing stairs does not make it worse, and there is no nausea. It lasts thirty minutes to seven days. The modern account is central sensitization (a pain system that has become oversensitive), not tight muscles.
It is the most common headache on earth, and the one with the worst name. Very little of it is about muscle tension. Almost none of it is about being tense.
What does a tension headache feel like?
- Both sides, pressing or tightening rather than throbbing.
- Mild to moderate — you can usually keep working.
- Not made worse by climbing stairs.
- No nausea. Light or sound sensitivity may be present, but not both.
- Thirty minutes to seven days.
If it throbs, if stairs make it worse, or if there is nausea, it is not tension-type. That is the whole differential (how you tell them apart). It is why so many people are treating migraine with the wrong expectations.
Episodic and chronic are different problems
Under 15 headache days a month is episodic. At 15 or more for over three months, it is chronic tension-type headache. That is a different conversation with a different treatment approach. The shift is usually gradual and usually goes unnoticed. That is why counting matters more than remembering.
What is the main cause of tension headaches?
Pericranial muscle tenderness (sore muscles around the skull) is real and measurable in many people with this. But it is not enough to explain it. The modern account is central sensitization. Repeated nociceptive input (pain signals) lowers the threshold of the pain-processing system. So ordinary load produces more signal than it used to. That is why it becomes more frequent over years rather than staying level. It is also why it responds poorly to escalating painkillers.
Two upstream drivers feed that sensitization directly — sleep that is short or shifted, and glucose instability (blood sugar swings) from irregular meals. The third is postural and work load that never releases. Those are the three levers, and none is a pill.
WHEN TO STOP CALLING IT TENSION-TYPE
- It throbs, or routine movement worsens it.
- There is nausea.
- It is strictly one-sided every time — side-locked.
- It is present on more days than not.
- You are treating it on ten or more days a month.
How do you treat a tension headache?
- Confirm the diagnosis by what it is not — the four features above.
- Count headache days and medication days for two weeks. Chronic tension-type with an overuse layer looks untreatable and is not.
- Address sleep timing and meal regularity before adding anything. That is because a preventive judged on top of those is judged unfairly.
- Load management: workstation, position changes, and the neck, which is frequently the driver in the ones that will not settle.
- Then consider a preventive if the frequency justifies it.
Frequently asked questions
Is tension headache caused by stress?
Stress is a trigger, not the mechanism — and the word hides the difference between this and migraine. Why “stress headache” is not a diagnosis.
Why do painkillers stop working?
Because past a certain number of medication days, they begin sustaining the pattern. For combination products and triptans, that is around ten days a month — how it unwinds.
Can tension-type become chronic?
Yes, and the shift is gradual. Fifteen or more days a month for three months meets the definition.
That is the subject of headache across the forehead.
Does massage or physical therapy help?
It helps the muscular and postural component and load tolerance, which is worth having. It rarely resolves an established chronic pattern on its own.
What can be mistaken for a tension headache?
Migraine, most often. If the pain throbs, if climbing stairs makes it worse, or if there is nausea, it is not tension-type. Treating it as tension-type sets the wrong expectations. A headache that sits on the same one side every time is also a different diagnosis. Those features, not how stressed you felt that day, are what separate them.
Which symptom is most indicative of a tension headache?
A pressing or tightening pain on both sides of the head that you can usually work through. It does not throb, climbing stairs does not make it worse, and there is no nausea. Light or sound sensitivity may be present, but not both. An episode can last anywhere from thirty minutes to seven days.
How do you relieve a tension headache?
Work on what feeds it: sleep that is short or shifted, irregular meals, and postural or work load that never lets up. Fix the workstation, change position often, and have the neck looked at if the headaches will not settle. Painkillers help less than people expect. That is because once combination products are used on about ten days a month, they start sustaining the pattern.
