Trigger point blog
One hundred in-depth articles built on the same clinical dataset as the rest of the site: every muscle deep-dive, pain-pattern explainer, treatment how-to and evidence review links straight back to the muscle and symptom pages it discusses.
Articles are written from the trigger-point literature — from Travell and Simons' original mapping work to current systematic reviews and randomised trials on dry needling and manual release — and each one lists the studies it draws on.
This is educational reference material, not a diagnosis. Techniques marked as clinician-only require professional training.

Your MRI is not a diagnosis: what scans show in people without pain
Disc bulges and degeneration show up on scans of people with no pain. What asymptomatic-imaging research means for how your pain should be assessed.

Self-treating a trigger point: pressure, heat and movement
Most trigger points respond to simple self-treatment — if the pressure is dosed right, the muscle is warmed and the shortened position that feeds the point is removed. A practical four-step plan, what the research supports, and when to stop and see a professional.

Subscapularis: the hidden muscle behind frozen shoulder
The largest rotator cuff muscle hides behind the shoulder blade and quietly steals your outward rotation — sending pain to the back of the shoulder, deep into the armpit and even in a band around the wrist. How to spot it and get the range back.

A grip that hurts and gives way: forearm trigger points
When jars slip, handshakes hurt and the kettle feels twice as heavy, the problem is often not the hand itself but trigger points in the forearm muscles that run it. How to tell, and what to do.

Dry needling vs manual pressure: what studies show
Is a needle into a trigger point better than a thumb? We review the systematic reviews and meta-analyses comparing dry needling with manual pressure and other treatments, and what the evidence means for your choices.

Shin pain when walking: tibialis anterior treatment plan
An ache along the front of the shin and into the ankle and big toe, worse on hills, stairs and long walks, is often driven by tibialis anterior trigger points. A two-week, step-by-step plan to find them, release them and stop them coming back.

Sternocleidomastoid: the neck muscle behind headaches
A muscle you can see in the mirror when you turn your head can produce forehead headaches, deep ear pain, a blocked ear and even a sense of imbalance — without the neck itself hurting. How the sternocleidomastoid does it, and how to check it yourself.

Tennis elbow that will not heal: the trigger points behind outer elbow pain
Outer elbow pain that lingers for months is often treated as a tendon problem and nothing else. Yet the wrist extensors, supinator, brachioradialis and even the triceps routinely refer pain to exactly that spot. How to tell a muscular contribution, and what to do about it.

Referred pain: why the spot that hurts is rarely the spot that needs treatment
The single most useful idea in trigger point science is also the most counterintuitive: a trigger point usually hurts somewhere else. What the research says about how referred pain works, why it fools patients and clinicians alike, and how to use it.

Calf cramps at night: a step-by-step plan for the gastrocnemius and soleus trigger points behind them
A cramp that wakes you at 3 a.m. is not usually a vitamin problem. Why trigger points in the two calf muscles lower the threshold for cramping, how to test each one, and a two-week plan that most people can run at home.

The infraspinatus: why the back of your shoulder blade makes the front of your shoulder hurt
The most common rotator-cuff source of deep front-of-shoulder pain sits on the back of the shoulder blade. Where the infraspinatus trigger points are, why their referral fools patients and clinicians alike, and how to find and treat them at home.

Groin pain that isn't a hernia: the adductor, pectineus and iliopsoas trigger points behind it
Groin pain is usually blamed on a strain or a hernia, but adductor, pectineus and iliopsoas trigger points reproduce the same complaint in people who train and in people who only sit. How to tell them apart at home, and a two-week plan.

Why pain spreads: satellite trigger points, and whether deactivating one quiets its neighbours
Pain that starts in one spot and, over months, spreads into a wider territory is one of the most common patterns in myofascial medicine. This evidence review looks at the satellite trigger point concept Travell and Simons described, what modern biochemistry adds to it, and what the treatment trials actually show about treating one point and quieting the others.

The headache that arrives at the end of the day: a suboccipital and trapezius treatment plan
A head that feels fine in the morning and aches in a band around the skull by late afternoon is usually a load problem, not a head problem. This treatment guide explains which neck and shoulder muscles drive that pattern, how to find the responsible points without pressing on anything dangerous, and a four-week plan that combines release, posture change and graded loading.

The piriformis: the muscle that imitates sciatica from deep in the buttock
Deep buttock pain that runs down the back of the thigh and worsens after sitting is often blamed on a disc. This muscle-focused guide explains what the piriformis does, why its trigger points copy sciatica so convincingly, how to test it safely at home, and what actually changes it over two to four weeks.

Burning pain between the shoulder blades at the desk: the trigger points that cause it
Interscapular burning that builds through a working day usually is not coming from the spine underneath it. This article explains which muscles refer pain into that strip between the shoulder blades, how to tell them apart at home, what to change at the desk, and the signs that mean you should be examined rather than treated.

Do stretching and exercise actually change a trigger point? What the trials show
Pressure and needles get most of the research attention, but stretching and loading are what most people actually do at home. We look at what controlled studies say about whether they change tender points, how strong the effect is, and why they matter most for stopping the pain from coming back.

Low back pain that flares when you stand: a step-by-step quadratus lumborum treatment plan
Deep, hard-to-point-at low back pain that gets worse the longer you stand, and eases when you sit or lie down, often comes from the quadratus lumborum. Here is how to find it, how to treat it week by week, and when to stop and get assessed.

Hands that go numb at night: the trigger points that imitate carpal tunnel syndrome
Waking with numb, tingling hands is usually blamed on the wrist. In a large share of cases the sensation is referred from trigger points in the scalenes, pectoralis minor, subclavius and forearm flexors. Here is how to tell the patterns apart and what to do first.

The muscle behind a stiff neck you cannot turn: levator scapulae trigger points
When turning the head to look over one shoulder is blocked by a sharp catch at the base of the neck, levator scapulae is nearly always involved. Here is how its referral pattern works, how to palpate it, and a release-and-move sequence that restores rotation.

Jaw pain, clicking and morning tightness: the chewing-muscle trigger points behind it
Jaw pain that is worse in the morning, a jaw that clicks or opens crookedly, and pain that spreads to the temple, ear or teeth usually involves masseter, temporalis and the pterygoids long before it involves the joint surfaces themselves.

Hip pain when you lie on your side: the gluteal trigger points behind it
Pain on the outside of the hip that wakes you when you roll onto that side is rarely the joint. Gluteus medius, gluteus minimus, quadratus lumborum and tensor fasciae latae refer pain into exactly that area — and each one has a different giveaway.

Dizziness when you turn your head: the neck trigger points that imitate a balance problem
Unsteadiness that appears only when the head moves is often cervical in origin. Sternocleidomastoid, scalene and suboccipital trigger points distort the neck's position sense and can produce dizziness, blurred vision and nausea without any inner-ear disease.

Heel pain on the first steps of the morning: the calf and foot trigger points behind it
Morning heel pain is usually blamed on the plantar fascia alone, yet soleus, gastrocnemius, quadratus plantae and abductor hallucis refer pain into exactly the same spot — and they respond to pressure release and loading.
