Tension headache

The commonest headache there is — a tight band around the head, on both sides, dull rather than throbbing. Most respond well to measures you can take yourself. A few turn out to be something else.

Where the pain is
Both sides. A band or vice around the forehead, often into the back of the head and neck.
Character
Dull, pressing, steady. Not throbbing, and not usually worse on movement.
Episodic or chronic
Most people get a few a month. Fifteen or more a month is chronic, and treated differently.

What is a tension headache?

Tension headache is the most common type of headache. It produces mild to moderate pain in the head, neck and sometimes behind the eyes. Most people describe it as a tight band around the forehead, or a vice pressing from both sides.

It comes on slowly rather than suddenly, affects both sides rather than one, and is usually not made worse by moving about — which is why people tend to carry on working through it. It often involves the back of the head and the neck as well.

Episodic or chronic?

The distinction matters more than it sounds, because the two are managed differently.

  • Episodic — a few headaches a month, each lasting from half an hour to a few days. Managed with the measures below and occasional painkillers.
  • Chronic — headache on fifteen or more days a month for over three months. At this point occasional painkillers stop being the answer and often become part of the problem. This is the point at which specialist assessment is worthwhile.

Is it really a tension headache?

Tension headache is the label most commonly applied to a headache that has not been examined, and a good proportion of headaches carrying it are something else. Two in particular:

  • Migraine — if the pain throbs, sits mainly on one side, worsens when you move, or comes with nausea or light sensitivity, that is migraine territory rather than tension. Moderate migraine is regularly mistaken for severe tension headache.
  • Cervicogenic headache — if it stays on one side, the neck is stiff and particular neck movements set it off, the source may be the cervical spine rather than muscle tension.

This matters because the treatments differ. Someone treating migraine as tension headache will usually find that nothing works, and conclude they have to live with it.

Compare all four types side by side.

Tension headache symptoms

  • Slow onset
  • Pain on both sides of the head
  • Dull pain, or a band or vice around the head
  • Pain that may involve the back of the head or the neck
  • Tenderness in the scalp, neck and shoulder muscles
  • Usually mild to moderate, occasionally intense

Nausea and vomiting are not features of tension headache — if they are present, migraine is more likely. Mild sensitivity to light or noise can occur but is uncommon.

Which muscles are involved

The pain of tension headache comes from the muscles covering the skull and the upper neck — across the forehead, over the temples, at the back of the head, and the muscles running up from the shoulders.

That distribution is why the headache is felt as a band rather than in one spot, and why it so often involves the neck at the same time. It is also why an examination involves pressing on these areas: tenderness in the scalp, temple, neck and shoulder muscles is one of the few objective findings in a condition with no test.

In some people a few of those points are distinctly more tender than the rest. Those are the ones that can be injected, which is why the examination is worth more than it appears.

What you can do yourself

Tension headache is one of the few headaches where self-management makes a substantial difference, and it is worth working through these properly before assuming medication is the answer.

Get the basics right first

Enough sleep, on a consistent schedule. Do not skip meals. Drink enough. Pace the day rather than sprinting at it. These sound trivial and they account for a surprising proportion of headaches.

Address the neck and shoulders

Heat to the neck and shoulders relaxes the muscles. Stretching and strengthening them helps more durably. If you work at a desk, the height of your screen and whether your forearms are supported matter more than any of it.

Relaxation, practised regularly

Physical and psychological relaxation techniques reduce how often tension headaches occur — but only if practised routinely rather than reached for during an attack. Guided attention through the body, releasing each area in turn, is one accessible method.

Learn to catch the tightening early

Most people can eventually recognise the muscle tension building before the headache arrives, and interrupt it. Biofeedback — where muscle activity is measured so you can see what relaxing actually feels like — is a structured way of learning that skill.

The painkiller trap

This is the most important thing on the page. Ordinary painkillers taken more than two or three days a week can begin causing headaches of their own — a dull daily headache that worsens as each dose wears off, prompting another dose.

It is the commonest reason a manageable tension headache becomes a daily one, it is frequently missed, and it is reversible. If your painkiller use has crept up, that is worth saying out loud at a consultation rather than leaving out.

How tension headache is diagnosed

Diagnosis is made from the history and a physical and neurological examination — the pattern, the character of the pain, what accompanies it, and tenderness in the scalp, neck and shoulder muscles. There is no test for tension headache.

Investigation is used to exclude other causes where the presentation is unusual, has changed, or the examination raises a question:

  • MRI — detailed imaging of the brain and blood vessels
  • CT — cross-sectional imaging where MRI is unsuitable
  • Blood tests — where an underlying condition is possible

Treating tension headache

For episodic tension headache, the measures above plus occasional painkillers are usually enough. Where headaches are frequent or have become chronic, treatment moves on:

  • Preventive medication — taken regularly rather than at the time of a headache, to reduce how often they occur.
  • Physiotherapy — where the neck and shoulder muscles are a significant contributor.
  • Trigger point injection — some people have distinctly tender points at the back of the neck or in the shoulders. Injecting local anaesthetic into these can relieve the pain and reduce recurrence.
  • Withdrawal of overused painkillers — where medication overuse has taken hold, this is the treatment, and it is worth doing with support rather than alone.

When to seek advice sooner

A sudden, severe headache unlike any you have had before, a headache with fever and a stiff neck, or one with new weakness, numbness, confusion or visual loss needs same-day assessment at an emergency department rather than a clinic appointment.

Short of that, a headache that has become daily, has changed in character, or no longer responds to what used to work is worth having assessed properly rather than continuing to treat.

Common questions

Is a tension headache caused by stress?

Stress is a common trigger, but so are poor sleep, skipped meals, sustained posture and eye strain. Many people find the headache arrives after a stressful period rather than during it, once they relax.

How do I know it is not a migraine?

Tension headache is dull, on both sides, and not usually worse on movement. Migraine throbs, tends to one side, worsens with movement and often brings nausea or light sensitivity. If yours matches the second description, it is worth having reassessed.

Can painkillers make it worse?

Yes, and this is the commonest trap. Taken more than two or three days a week they can begin causing a daily headache of their own. It is reversible once recognised.

Will a scan show anything?

Not for tension headache — there is nothing for it to show. Imaging is used to exclude other causes when something in the history or examination warrants it, not to confirm the diagnosis.

When is it worth seeing a specialist?

When headaches occur on fifteen or more days a month, when your painkiller use has been climbing, when the pattern has changed, or when you have been treating it as tension headache for years without improvement.

Do I need a referral?

No. You can book directly. Bring a record of your headaches if you have kept one, and a note of what you have been taking and how often.

If headaches have become a daily fact of life, or the painkillers have stopped working, that is worth looking at properly.
