Exploring the connection between muscle tightness and headaches

Headaches can be mildly annoying or completely debilitating, and they affect people of every age and walk of life. One contributor is easy to miss, though, and it lives at the base of your skull and across the tops of your shoulders.

Plenty of things can set off a headache, but muscle tightness in the neck and shoulder region plays a bigger role than most people realise. When these muscles get tight and stay tight, they can drive headaches that keep coming back. In this article we walk through what the research says about that connection, from large population studies and meta-analyses through to clinical trials, so you can understand what is happening and what you can do about it.

The muscles involved

Two groups of muscles come up again and again in the research. The suboccipital muscles are a set of four small muscles that sit right at the base of the skull, connecting it to the top two bones of the neck. The upper trapezius runs from the base of the skull and neck out across the shoulders. Both are working constantly to hold your head up, and both are prone to becoming tight and knotted when you spend long hours sitting, looking down at a screen, carrying stress in your shoulders or doing anything that loads the neck for extended periods.

When a muscle stays under that kind of load, it can develop trigger points. These are small, hyperirritable spots within a tight band of muscle that are tender to press on and, importantly, can refer pain to somewhere else. For the suboccipitals and upper trapezius, that somewhere else is often the back of the head, the temples and behind the eyes.

How strong is the link?

Stronger than most people expect. The relationship between neck pain, muscle tenderness and headache has now been examined in population studies, systematic reviews and meta-analyses, which are the highest tiers of evidence we have.

That finding lines up with what a Danish population study reported a few years earlier. In a sample of nearly 800 adults, neck pain over the previous year was reported by 86% of people with migraine or tension-type headache, compared with 57% of those without a primary headache, and pericranial muscle tenderness was significantly higher in the headache groups. The more headache types someone had, the more likely they were to have neck pain as well.

Does releasing tight muscle help?

This is where the evidence moves from association to intervention, and it is encouraging.

Why tight muscles cause head pain

A few mechanisms are thought to be working together.

• Referred pain from trigger points. Trigger points send pain signals that the brain interprets as coming from a different area. The suboccipitals and upper trapezius have well-mapped referral patterns into the back of the head, the temples and around the eyes, which is why a tight neck so often feels like a headache.
• Sensitisation of the nervous system. A trigger point is a source of constant, low-level nociceptive input. Over time this can lower the threshold at which the brain registers pain, which is why people with long-term headache tend to be more pressure-sensitive not just in the neck but across the body.
• Reduced blood flow. Muscle that stays contracted restricts its own circulation, leaving tissue short on oxygen and slow to clear metabolic by-products. That environment keeps trigger points irritable and keeps the cycle going.
• Nerve irritation. The greater occipital nerve passes through and around the suboccipital and upper trapezius region on its way to the scalp. Tight, congested tissue in this area can irritate it and contribute to pain that radiates over the back of the head.

What you can do about it

The good news in all of this is that muscle tension is something you can influence. These strategies are the ones that sit closest to the research.

• Regular, targeted stretching. Gentle stretches for the neck, upper shoulders and the suboccipital region help reduce resting tension and make trigger points less likely to form. Little and often beats one long session.
• Self release of trigger points. Sustained pressure on a trigger point, sometimes called ischaemic compression, is the self-applied version of what the manual therapy trials above were doing. Applying steady pressure to the suboccipitals at the base of the skull, then letting the muscle soften, can improve local blood flow and reduce the referred pain.
• Move more, sit less. Long stretches of stillness at a desk or on a phone load these muscles far more than any single bad posture does. Changing position regularly reduces the sustained strain that builds tension in the first place.
• Manage stress. Stress shows up in the shoulders. Breathing work, short walks and any practice that lets the upper body genuinely let go will lower the baseline tension that feeds trigger points.
