A client comes in complaining of a headache behind the eye. You press a knot at the top of the shoulder, and they say, “That’s it — that’s the spot.” Nothing about that makes sense until you understand trigger points and the phenomenon of referred pain. For anyone learning massage therapy, this is one of the most useful concepts to grasp early, because it explains why treating the painful area alone so often fails.
What a trigger point is
A trigger point is a hypersensitive spot within a taut band of skeletal muscle. Under the fingers it usually feels like a small nodule or a tight cord running along the direction of the muscle fibres. Pressing it is distinctly tender, often more so than the surrounding tissue.
Two categories are commonly described:
- Active trigger points produce pain without being touched. The client is already aware of the discomfort.
- Latent trigger points are painful only when compressed. They may not bother the client day to day but can still restrict range of motion and contribute to fatigue.
The precise physiology is still debated in the research literature, and reliability of manual identification varies between practitioners. What is well documented is the clinical pattern: localised tender nodules that reproduce a client’s familiar pain when pressed.
Referred pain: the confusing part
Referred pain is discomfort felt in a location away from its actual source. It is not imagination and it is not random — the patterns are consistent enough to have been mapped in clinical texts for decades.
The mechanism is generally explained by convergence in the nervous system: signals from different tissues arrive at the same segments of the spinal cord, and the brain, receiving an unusual input, attributes it to a more familiar origin. The same principle explains why cardiac pain is often felt in the left arm and jaw.
| Muscle | Typical referral area |
|---|---|
| Upper trapezius | Side of the neck up towards the temple |
| Sternocleidomastoid | Forehead, around the eye, ear region |
| Infraspinatus | Front of the shoulder and down the arm |
| Gluteus medius | Lower back and along the side of the hip |
| Piriformis | Buttock and posterior thigh |
| Masseter | Jaw, cheek and around the ear |
Referral patterns are guides, not guarantees. Individual variation is normal, and the client’s own report always outranks the map.
What tends to create them
- Sustained low-level contraction — holding a posture for hours, such as at a desk or behind a wheel.
- Sudden overload — lifting awkwardly, an unaccustomed workout, a fall.
- Repetitive movement in a narrow range, common in manual trades and in musicians.
- Protective guarding around an injury, where surrounding muscles tighten to limit movement.
- General contributors such as poor sleep, dehydration and prolonged stress, which lower tissue tolerance.
Locating them during a session
- Take a history first. Ask where the pain is felt, when it appears, and what movements provoke it.
- Palpate along the fibre direction, not across the muscle randomly. Taut bands run lengthwise.
- Use flat palpation against underlying bone for broad muscles, and pincer palpation — thumb and fingers — for muscles you can lift, such as the upper trapezius.
- Apply steady, moderate pressure and wait a few seconds. Ask whether the sensation stays local or travels.
- Confirm with the client: the key question is whether the sensation reproduces their familiar complaint.
Release techniques
| Technique | How it is applied |
|---|---|
| Ischaemic compression | Sustained direct pressure held until tenderness noticeably decreases |
| Stripping | Slow gliding stroke along the taut band, following the fibre direction |
| Cross-fibre friction | Short strokes perpendicular to the fibres to mobilise the band |
| Positional release | Shortening the muscle passively and holding it while the tissue settles |
| Post-treatment stretch | Gentle lengthening once the area has softened, to restore range |
Pressure should sit in a tolerable range — commonly described to clients as “strong but manageable”. Pain that causes breath-holding, flinching or clenching is counterproductive: the body responds by guarding, which is the opposite of what the technique is meant to achieve.
Aftercare and expectations
- Mild soreness for a day or two after treatment is common, similar to post-exercise stiffness.
- Encourage normal movement rather than complete rest of the treated area.
- Recurring trigger points usually indicate an ongoing cause — a workstation setup, a training habit, a sleeping position. Addressing that matters more than the number of sessions.
- Progress is often gradual. Long-standing patterns rarely resolve in a single appointment.
When to refer out
Massage therapists work within a defined scope. Certain presentations call for medical assessment rather than manual treatment:
- Chest pain, or pain radiating into the jaw or left arm, especially with breathlessness.
- Numbness, tingling or weakness that follows a nerve distribution.
- Pain following significant trauma, or accompanied by fever, unexplained weight loss or night pain.
- Swelling, heat and redness suggesting inflammation or infection.
- Any symptom that worsens steadily despite appropriate treatment.
Referring is not a failure. Recognising the limits of manual therapy is part of practising responsibly, and clients notice when a therapist prioritises their safety.
Conclusion
Trigger points explain a puzzle that frustrates a lot of clients: pain that keeps returning to a place that never seems to be the problem. Learning to palpate taut bands, recognise referral patterns and apply pressure that the tissue can accept turns a general relaxation massage into targeted, purposeful work.
If you want structured practice in palpation, anatomy and treatment sequencing, the free massage therapy and anatomy courses available on Cursa are a solid place to build those foundations before working with clients.
