Musculoskeletal Pain
Myofascial Pain Syndrome
The ache moves. It is in your cheek one day, your ear the next, your tooth by the weekend — but the dentist finds nothing and the antibiotics do nothing. Myofascial pain is a muscle problem that sends pain elsewhere: hyperirritable knots (trigger points) in the chewing and neck muscles. Finding them is the diagnosis most evaluations skip.
Symptom Profile
Trigger Points and Referred Pain Patterns
The trigger point is the signature finding: a tender knot inside a taut muscle band that refers pain in a predictable pattern — a pattern that does not follow nerve maps, which is why imaging and standard workups miss it.
- Deep ache in the affected muscle that builds with use or sustained posture
- Pain that jumps to distant spots — teeth, temples, ear, around the eye
- Palpable tight bands with exquisitely tender knots at the center
- Pressing the knot reproduces your exact complaint
- Limited opening from muscle guarding rather than a joint block
- Stiffness and fatigue that worsen through the day and barely ease with rest
- Headaches fed by sustained jaw or neck muscle tension
- Sleep disrupted because no jaw or neck position is comfortable
Referred pain is why this condition is easy to mistake for something else: masseter trigger points feel like tooth pain, neck-muscle points like sinus or ear trouble. The pain is real — its address is simply not where it is felt.
Tight, aching jaw muscles that splints and stretching have not resolved? The trigger source is often somewhere else. Dr. Chung's 60–90 minute diagnostic consultation is built to find it.
Differential Diagnosis
Myofascial Pain vs. TMJ Disorders
Myofascial pain and true TMJ joint disorders are different conditions that often coexist — and confusing them is one of the most common reasons treatment stalls.
Joint disorders live inside the joint itself: disc displacement, inflammation, degeneration. The pain sits directly in front of the ear, usually with clicking or grating. In myofascial pain, the joint is normal — the muscles around it are the problem.
Myofascial Pain
- Pain originates in muscle tissue, not the joint space
- Trigger points identifiable on palpation within taut bands
- Referred pain follows established myofascial maps
- Joint sounds may be absent or incidental
- Pain worsens with sustained muscle activation or poor posture
- Range-of-motion limitation is due to muscle guarding, not mechanical block
- Imaging of the TMJ is typically unremarkable
TMJ Disorders (Intra-Articular)
- Pain originates within the temporomandibular joint capsule
- Preauricular tenderness directly over the joint
- Joint sounds on auscultation (clicking, crepitus)
- Disc displacement demonstrable on MRI
- Condylar morphology changes visible on CBCT
- Range-of-motion limitation from mechanical obstruction
- Myofascial pain may be present as a secondary feature
The critical distinction: in isolated myofascial pain, the joint itself is normal. Treating the wrong one — or treating only one of a pair that coexists — keeps the symptoms alive. That is why the differential comes before the treatment plan.
Muscular Anatomy
Masticatory and Cervical Muscles Affected
Several muscles can carry this condition. Each has its own trigger point location and its own referred-pain signature — which is how the true source is traced.
Masseter
The main chewing muscle, in the cheek. Its trigger points refer pain to the back teeth and ear — so common that they are frequently mistaken for tooth infections or ear problems. Pain typically intensifies with chewing and clenching.
Temporalis
The fan-shaped muscle across the temple. Its trigger points project to the upper teeth, forehead, and temple — the classic tension-type headache pattern. Among the most common muscular headache sources we find.
Lateral Pterygoid
Deep inside the jaw, it guides opening. Its trigger points refer to the sinus area and in front of the ear. Too deep to reliably palpate directly, it is traced through associated findings.
Medial Pterygoid
The masseter's deep partner. Trigger points refer to the throat and the joint — patients describe a deep ache in the cheek or discomfort when swallowing.
Sternocleidomastoid (SCM)
The prominent neck muscle. Its trigger points refer to the forehead, around the eye, and the cheek — closely mimicking migraine or sinus headache. They can even produce tearing and eye redness, deepening the confusion.
Trapezius
The large muscle of the neck and shoulder. Its upper trigger points send pain up the neck to the temple — the tension-headache broadcast tower. Desk posture and forward-head work posture are the classic activators.
Clinical Protocol
Diagnostic Protocol
Imaging cannot diagnose myofascial pain — the diagnosis is clinical, built from systematic examination of the muscles themselves.
Hands-on examination of every chewing and neck muscle — taut bands, trigger points, and reproduction of your exact pain, documented on a standardized map.
Objective measurement of pain thresholds — detects whether the nervous system itself has become sensitized, which changes the treatment plan.
Calibrated pressure readings at trigger point sites — an objective number to track your response across visits.
Ruling out what coexists or mimics: joint pathology, nerve pain, headache disorders. Imaging is ordered only when a structural suspect appears.
The output is a definitive muscular diagnosis, not a symptom label: a documented map of involved muscles, trigger point severity, and referred pain patterns that drives your individual plan.
Clinical Guidance
When to See a Specialist
Most myofascial pain is treated symptomatically — painkillers, a generic mouth guard, a physical therapy referral — without ever mapping the muscles responsible. When that has failed, the next step is a specialist who maps them.
- Orofacial, jaw, or neck pain lasting more than three months without a diagnosis
- Pain treated as a dental, sinus, or ear problem — without resolution
- Headaches that track with clenching, neck tension, or desk posture
- Jaw fatigue or stiffness that limits chewing, speaking, or yawning
- Ear fullness or pain with a clean ENT evaluation
- Prior treatments that brought only temporary relief
- Pain that keeps spreading to new areas
- Sleep disrupted by facial or jaw muscle discomfort
Untreated, chronic myofascial pain can sensitize the nervous system itself — the point at which pain becomes self-sustaining and harder to reverse. Early, accurate diagnosis is the best insurance against that progression.
Frequently Asked Questions
Myofascial Pain: Common Questions
What is the difference between myofascial pain and a regular muscle strain?
A strain is an acute injury — torn fibers that heal on their own over weeks. Myofascial pain is chronic: trigger points form inside taut muscle bands, producing persistent pain and referred patterns that never follow nerve maps. A strain resolves; myofascial pain needs targeted treatment of the trigger points themselves.
Can myofascial pain syndrome in the jaw cause headaches?
Yes — referred pain from jaw and neck trigger points is a well-documented headache source. Temple-muscle trigger points mimic tension-type headache; neck-muscle points project behind the eye. In some patients with chronic tension-type headache, myofascial trigger points are part of what drives the pain.
How is myofascial pain syndrome diagnosed?
By systematic hands-on examination, not imaging. Palpation finds the trigger points — and pressing one reproduces exactly your pain. Quantitative sensory testing and pressure algometry can add objective measurements. MRI or CBCT cannot show myofascial pain; they are used to rule out other conditions.
What treatments are available for myofascial pain syndrome?
Treatment is matched to the muscles involved: trigger point injections or dry needling to deactivate the nodules, myofascial release and manual therapy, appliance therapy to unload clenching, and medication when appropriate. A structured home program — posture, ergonomics, exercise — is what makes the improvement last.
When should I see a specialist for myofascial pain?
When facial, jaw, or neck pain has lasted more than three months without responding to ordinary treatment — especially if it worsens with chewing or posture, or has been treated as a dental, sinus, or ear problem without resolution. Early diagnosis matters: chronic myofascial pain becomes harder to reverse the longer it runs.
If you have been living with chronic jaw, face, or neck pain and have not received a definitive muscular diagnosis, the source of your pain may not have been identified.
Dr. Sang H. Chung is a Board Qualified Orofacial Pain Specialist who systematically evaluates each muscle of the masticatory and cervical systems to identify the specific trigger points and referred pain patterns responsible for your symptoms.
