Trigger Point Therapy: Releasing Knots That Cause Referred Pain

You know that hard, tender lump you sometimes find in your shoulder or neck — the one that feels like a little pebble under the skin and hurts when you press it? That is a trigger point, and it may be doing something far stranger than just hurting where it sits. Trigger points have a peculiar habit of referring pain to other parts of the body, which is why the sore spot you feel and the knot causing it are sometimes in completely different places.

Trigger point therapy is a targeted approach to finding and releasing these knots. This guide explains what trigger points are, how they cause referred pain, and what a session of trigger point therapy actually involves.

What Exactly Is a Trigger Point?

A trigger point — sometimes called a muscle knot — is a tight, hyper-irritable spot within a band of muscle. It forms when muscle fibres become stuck in a contracted state and are unable to relax. The result is a small, hard nodule that is tender to the touch and can cause a range of symptoms.

Trigger points form for a variety of reasons:

• Overuse: Repetitive movements or prolonged muscle contraction (like sitting at a desk all day) can cause fibres to become stuck.
• Injury: Muscle strain or trauma can leave behind trigger points as the tissue heals.
• Stress: Chronic stress causes you to hold tension in muscles, which contributes to trigger point formation.
• Poor posture: Sustained poor posture overloads certain muscles and leaves them prone to knots.

Most people have at least a few trigger points at any given time. The question is whether they are causing problems — and for many people, they are.

The Strange Phenomenon of Referred Pain

Here is where trigger points get interesting. A trigger point does not just hurt where it is — it can cause pain in a completely different location, a phenomenon known as referred pain. This happens because the trigger point sends pain signals that the brain interprets as coming from elsewhere.

Some classic examples:

• A trigger point in the neck can cause a headache at the base of the skull or behind the eye.
• A trigger point in the shoulder can cause pain that travels down the arm.
• A trigger point in the glutes can mimic sciatica, causing pain down the leg.
• A trigger point in the upper back can cause chest or shoulder-blade pain.

This is why treating the place that hurts is sometimes not enough. If the pain is referred, the real source is elsewhere — and a skilled trigger point therapist knows how to find it.

Active vs Latent Trigger Points

Trigger points come in two main types:

• Active trigger points: These cause pain even when the muscle is at rest. They are the ones producing symptoms you actually notice.
• Latent trigger points: These are dormant — they do not cause pain unless pressed, but they can cause stiffness, weakness, and restricted movement, and they can become active under stress or overuse.

Many people carry latent trigger points for years without realising it, experiencing only vague stiffness or reduced range of motion until something activates them.

How Trigger Point Therapy Works

Trigger point therapy is a focused, precise technique. Rather than massaging the whole body broadly, the therapist works to locate specific trigger points and release them. Here is what a session typically involves:

• Assessment: The therapist asks about your pain and uses their knowledge of referral patterns to locate likely trigger points. They may press specific areas and ask whether it reproduces your familiar pain.
• Location: Once a trigger point is found, the therapist applies sustained, focused pressure directly on the knot.
• Release: The pressure is held — often for 30 to 90 seconds — until the muscle releases and the tension softens. This can feel intense, often described as a "good pain."
• Integration: After releasing trigger points, the therapist may use broader massage and gentle stretching to help the muscle settle into its new, relaxed state.

The experience is different from a relaxation massage. It is more clinical and targeted, and the pressure is concentrated. But the results can be dramatic — a stubborn headache or a persistent shoulder ache can resolve remarkably quickly when the right trigger point is released.

The Benefits

Trigger point therapy offers several specific benefits:

• Targeted pain relief: By addressing the actual source of pain, it can resolve symptoms that general massage misses.
• Reduced referred pain: Releasing a trigger point in one area can eliminate pain in another.
• Improved range of motion: Releasing knots restores flexibility and movement.
• Headache relief: Many tension headaches are linked to trigger points in the neck and shoulders.
• Better muscle function: Muscles with trigger points are weaker and less efficient; releasing them restores function.

What It Feels Like

Be prepared: trigger point therapy can be intense. The pressure is focused and sustained, and when the therapist hits the right spot, you may feel a deep ache that radiates to your familiar pain area — which is actually a good sign, because it confirms the source has been found.

The release itself often feels like the muscle suddenly "letting go." Afterward, the area may feel tender for a day or two, similar to post-workout soreness, but the underlying pain is typically reduced. Drinking water helps your body clear the metabolic waste that is released when trigger points break down.

Frequently Asked Questions

Is trigger point therapy painful?

It can be intense and produce a deep, aching sensation, but it should feel like a "good pain" that is releasing tension, not a sharp or unbearable pain. Your therapist will work within your tolerance.

How is trigger point therapy different from deep tissue massage?

Deep tissue massage works broadly on the deeper layers of muscle, while trigger point therapy targets specific knots with sustained, focused pressure to release them and their referred pain patterns.

How many sessions of trigger point therapy do I need?

Some trigger points release in a single session, while stubborn ones may need several sessions over a few weeks. Your therapist can assess and recommend a plan based on how your muscles respond.

Why does the pain come back after trigger point therapy?

If the underlying cause — poor posture, overuse, stress — is not addressed, trigger points can reform. Pairing therapy with posture correction, stretching, and stress management provides more lasting relief.

Can trigger points cause headaches?

Yes. Trigger points in the neck and shoulder muscles are a common cause of tension headaches, and releasing them often provides significant relief.
