The headache that arrives at the end of the day: a suboccipital and trapezius treatment plan

Headaches that come from the muscles of the neck and shoulder have a signature: they build through the day. The head is clear on waking, the first hint appears after a few hours at a screen or behind the wheel, and by evening there is a tight band across the forehead, the temples, or the base of the skull. Weekends and holidays are better.

That timing is the opposite of what sinister headaches do, and it matches what we know about sustained low-level muscle load. Holding the head a few centimetres forward of the shoulders multiplies the work of the suboccipital muscles and the upper trapezius hour after hour, and sensitised trigger points in those muscles refer pain upward into the head (travell1942, simons2004, fernandez2006).

The muscles most often responsible, in the order to check them: the suboccipital group at the base of the skull, the upper trapezius, the splenius capitis, the sternocleidomastoid, and — when the pain sits at the temple — the temporalis and masseter.

For the terminology and interpretation used here, compare What are trigger points?; Primary vs secondary trigger points; How to read referred pain maps. These guides distinguish the definition of a trigger point, its classification and the limits of a referred-pain map.

Work only on muscle, never on the front or side of the neck where the vessels and the windpipe sit. Everything in this plan happens behind the line of the ear or on the shoulder.

Suboccipital group: lie on your back with a tennis ball in a sock, or your own fingertips, under the base of the skull just beside the midline. Let the weight of the head do the work. A relevant point reproduces a familiar ache that spreads over the skull — that recognition is the finding that matters, not the intensity of the pressure.

Upper trapezius: pinch the top of the shoulder between thumb and fingers, about halfway between the neck and the shoulder tip, and roll the muscle gently. The point that matters reproduces the temple or behind-the-eye component of your headache.

Sternocleidomastoid: turn the head slightly away, pinch the muscle between thumb and finger well below the ear, and hold. Stay on the muscle belly; if you feel a pulse under your fingers, move back.

Sustained pressure of 30 to 90 seconds, up to the level of 'good pain', is the dose used across the manual-therapy literature (moraska2017, vier2019). More force is not more treatment.

Week one — reduce sensitivity. Treat the suboccipital points and the upper trapezius once or twice a day as described above, then take the neck through a slow, comfortable range: chin slightly in, ear toward each shoulder, turn to each side. The goal is a headache that is easier to switch off, not yet a headache that never starts.

Weeks two to four — change the load. Release alone fades if the working day keeps re-sensitising the same muscles. Three changes carry most of the weight: raise the screen so the top edge is at eye level; take a two-minute standing break every 30 to 40 minutes; and add a light strengthening dose for the deep neck flexors and the lower trapezius — slow chin tucks and prone or band rows, ten to fifteen repetitions, once a day. Trials of exercise programmes for neck-related headache show exactly this pattern: gradual improvement over weeks, held at follow-up, when loading and habit change accompany the hands-on work (espejo2017, cerezo2016, navarro2020).

Judge the plan on the month, not on the day. A useful record is a simple diary: time the headache starts, intensity out of ten, and what you did that day. If the start time moves later and the peak intensity drops, the plan is working even while some days are still bad.

If four weeks of consistent self-care reduce the headache but do not resolve it, a clinician can add two things you cannot do yourself: dry needling of the suboccipital and trapezius points, which trials support as at least as effective as manual pressure for short-term relief (cummings2001, tough2007, kalichman2010), and a proper examination of the neck joints, which sometimes contribute their own referral.

Stop self-treating and get assessed promptly if the headache is new and clearly different from anything you have had, arrives suddenly at full intensity, wakes you at night and stays, comes with fever or a stiff neck you cannot bend forward, or brings any neurological symptom — slurred speech, double vision, weakness, or numbness on one side. The end-of-day pattern described here is reassuring precisely because it is mechanical, gradual and familiar; anything that breaks that pattern deserves a professional look.
