“Trigger points” are commonly used to describe tender areas in muscle that may reproduce local or referred pain when pressed. Trigger-point therapy can be useful as a way of treating muscular tenderness, but the idea that every painful spot is a clearly identifiable “knot” with one specific cause is too simplistic.
The safest approach is to use trigger-point techniques as one part of a broader assessment rather than treating palpation findings as a precise diagnosis.
What Is a Trigger Point?
A myofascial trigger point is usually described as a tender point within a muscle that may reproduce familiar pain and sometimes refer pain elsewhere.
However, there is no universally accepted gold-standard diagnostic test. A systematic review and meta-analysis found only moderate agreement between clinicians using manual palpation to identify trigger points, with tenderness and pain recognition being more reliable than findings such as a taut band or local twitch response.

Why Does That Matter?
If two clinicians cannot always identify the same trigger point in the same place, it is better to treat the finding as a useful clinical observation rather than proof of a specific lesion inside the muscle.
Muscular tenderness can occur with overload, stress, prolonged positions, training changes, injury, sleep disruption or persistent pain. The tender area may be relevant, but it is rarely the whole story.
How Trigger Point Therapy Is Used
Trigger-point therapy generally involves controlled pressure or soft-tissue techniques applied to a tender area. The therapist may then reassess pain or movement to see whether the treatment produced a useful change.
More pressure is not automatically better. Treatment should stay within a tolerable range and should not be based on the idea that the therapist must “destroy” or “release” a knot.
What Trigger Point Therapy May Help With
Local muscular tenderness
Targeted pressure may reduce the perception of tenderness for some people, at least temporarily.
Short-term range of motion
If muscle sensitivity is limiting movement, targeted treatment may make a movement feel easier in the short term.
Muscular tension
Some clients find pressure to a tender area followed by broader massage helps reduce the feeling of tightness.
Awareness of aggravating factors
Treatment can be useful when it leads to a broader discussion about training load, prolonged positions, recovery, sleep or strength rather than simply chasing the same tender spot repeatedly.
What Trigger Point Therapy Cannot Reliably Do
- It cannot diagnose every cause of pain.
- It cannot guarantee permanent removal of “knots.”
- It cannot correct posture or joint alignment.
- It cannot replace rehabilitation after injury.
- It should not be used to explain neurological symptoms such as progressive weakness or numbness.
What About Referred Pain?
Pressing a tender muscle can sometimes reproduce pain in another area. That can be clinically useful, but referred pain patterns are not unique enough to diagnose every condition.
For example, shoulder or neck discomfort may be muscular, but it can also come from joints, nerves or other structures. Persistent or unusual symptoms should not be assumed to be a trigger point simply because pressure reproduces pain.
Trigger Point Therapy vs Deep Tissue Massage
| Feature | Trigger-point therapy | Deep tissue massage |
|---|---|---|
| Main focus | Specific tender areas | Broader muscular tension |
| Pressure | Targeted and controlled | Slow, firm techniques where appropriate |
| Goal | Reduce tenderness or improve movement | Improve comfort and reduce muscular tension |
| Diagnosis | Palpation is not perfectly reliable | Not a diagnostic test |
If your main concern is broader muscular tightness, our Deep Tissue Massage service may be more relevant.
What About Dry Needling?
Dry needling is a separate intervention that uses fine needles and should only be performed by an appropriately trained practitioner.
A 2025 systematic review of needling for myofascial pain found improvements in pain and disability compared with some non-pharmacological treatments, but the authors also called for higher-quality trials. This does not prove that every painful spot should be needled or that trigger-point diagnosis itself is perfectly reliable.

What Can Make a Tender Area More Noticeable?
Local muscular tenderness can become more noticeable after unfamiliar exercise, repeated loading, prolonged positions, reduced recovery or periods of higher stress. These factors do not prove that a discrete “knot” is the cause of pain, but they can help explain why an area feels more sensitive at certain times.
The practical response is usually to review recent load, movement, sleep and recovery rather than repeatedly pressing harder on the sore spot.
What Can You Do Between Sessions?
- Keep moving: avoid staying in one position for long periods.
- Build strength: use appropriate resistance training for the affected region.
- Manage training load: avoid sudden large jumps in volume or intensity.
- Use self-massage carefully: a ball or foam roller can be useful, but more pain is not better.
- Reassess recurring symptoms: if the same area repeatedly returns, look beyond the tender spot.
When Should You Seek Assessment?
Trigger-point work is not a substitute for medical or rehabilitation assessment when symptoms include:
- progressive weakness
- persistent numbness or tingling
- severe or rapidly worsening pain
- significant swelling or redness
- symptoms following major trauma
- new bladder or bowel changes
- pain that repeatedly returns without a clear muscular explanation
Frequently Asked Questions
Are muscle knots real?
People can certainly have tender, tense areas in muscle. The term “knot” is a useful everyday description, but it should not be treated as a precise structural diagnosis.
Can trigger points cause referred pain?
Pressing a tender area can reproduce pain elsewhere in some people. Referred pain patterns can be useful clinically but are not specific enough to diagnose every condition.
Should trigger-point therapy hurt?
It can feel intense, but excessive pain is unnecessary. Pressure should be tolerable and should not leave symptoms significantly worse.
Can trigger-point therapy cure chronic pain?
No. Persistent pain is usually influenced by multiple factors, and trigger-point treatment should be considered only one possible component of management.
How often should I have trigger-point treatment?
There is no evidence-based fixed schedule. Continue only if the treatment provides a meaningful benefit and supports movement or rehabilitation.
