Neck and Head
Pain is the most common expression of myofascial
dysfunction yet chronic headache sufferers respond badly to
diagnoses of muscle tension headache. The labels of "vascular"
headache or "neurological disease" seem more respectable,
more likely to be taken seriously. But "vascular" doesn't stop at
the head; "neurological" isn't restricted to the brain or spine.
Tight muscles and fascia press, shear, block, and strangle both
blood vessels and nerves throughout the body. “Muscle tension
headache” can mean very simply “headache due to tight muscles” but
from there it has been a short trip to “You’re just tense” and . . .
“Have you considered psychiatric counseling?” with the clear
implication that...
The pain is not real. YOU are just
crazy.
Many pains do indeed have psychiatric components,
but the psychogenic diagnosis is woefully overdone. Strangely, it is
rarely applied to knee pain, big toe pain, or shoulder pain, but is
used all too often by the physician, who, when asked for the
underlying cause of head pain, cannot bring himself to say “I don’t
know.” And there's a lot to know. Over 20 muscles (primarily of the
neck) refer pain to the head. Several refer pain
specifically to the eye. At least three refer pain directly to the
teeth for reasons that will never be relieved by fillings or
repeated root canals.
Of particular concern is strain or
compression of the trigeminal nerve and its branches which mediate
tissue inflammation, vasodilation and vascular permeability -- all
issues in migraine. Over the last few years, plastic surgeons have
verified the muscle-migraine connection beginning with the odd
observation that Botox injections in the frontalis and corrugator
muscles of the brow also eliminated migraines.
If irritated
muscles and nerves fire off an inflammatory response and
vasodilation, is the resulting headache "muscular," "neurological,"
or "vascular"? Perhaps the only real answer is "all of the above"
because amazingly enough, it all functions together -- or
dysfunctions together.
For patient or physician, the
following pain patterns may look surprisingly familiar and will, we
hope, point the user in the direction of truly effective treatment.
In the following illustrations, black dots indicate
common trigger point locations; red areas indicate the pain referred
by the trigger point. You can evaluate these muscles with the Cervical and Masticatory Tests
excerpted and adapted from our Range-of-Motion
Testing Charts.
- Upper Trapezius > Tension headache and
"bursitis".
The trapezius muscle of the back and neck is the
single muscle most likely to have trigger points in both adults
and children.
The
upper trapezius refers a "fish-hook" pain pattern up the back side
of the neck to the head, and around the temple to the eye.
There
may be goosebumps to upper arm and thigh possibly with nausea and
visual disturbances. The nauseating pain of a one-sided trapezius
headache is commonly diagnosed as "migraine" although migraine
meds (most of which began as anti-seizure medications) often fail
to relieve the pain.
"Bursitis" and upper back pain may
arise from the upper and lower fibers of the same muscle; see Introduction to Shoulder Pain.)
Problems often begin with heavy bags or purses, or a habit of
balancing phones between head and shoulder. Trapezius is also
strained by tight SCM or scalene muscles.
- Sternocleidomastoid
(SCM) > Dizziness, nausea, "migraine" and
"sinus" pain.
Because of its intimate involvement
with brain stem and the vagus nerve, the SCM muscle of the
neck produces a long list of symptoms; pain appears in
the head and face. Neurological symptoms manifest as
nausea, motion sickness, and balance problems. These are
commonly mistaken for migraine, sinus headache, inner-ear
problems, trigeminal neuralgia -- and so on.
SCM has one of the
most extensive patterns of pain and dysfunction, yet is one
of the easiest muscles to self-treat. Click the link to see an
info page on this muscle.
- Scalenes > "Thoracic outlet" and "carpal tunnel"
syndromes; chest, arm, and upper back pain.
Scalenes
contribute to severe tension headache and are one of the leading
causes of "carpal tunnel syndrome." On the list of a half-dozen
possible causes, the carpal tunnel itself is dead last.
This is one of the reasons why carpal tunnel surgery is so
ineffective. Check before you cut!
Notice
also the fingerlike projections of pain extending down the chest.
This is easily confused with angina. If you think you are having
heart problems, get to a doctor immediately! If, however, no
cardiac problems are found, consider other muscles,
especially if the chest pain was accompanied by a tingly thumb or
index finger. Scalene pain typically extends down the upper arm,
skipping the elbow. There may also be severe pain at the vertebral
border of the scapula.
All of these patterns may be painfully
familiar to wrestlers and Aikidoists who have suffered too many
"neck-a-nage's." In Aikido, students who don't understand
kokyu-nage techniques (based on balance and timing) tend to
interpret what they think they see as: "Swing your partner
around by the neck then drop him on his head," a painful variation
on the game of “Hangman.” In professional football, doing the same
thing to a large, padded, extremely fit refrigerator-sized
opponent by grabbing his face-guard will get you an instant
15-yard penalty, for very good reason.
The consequences of injury to these muscles
can be extremely painful or disabling. The electrical supply
for arm and fingers comes from the brachial
plexus, the “wiring harness” originating in the neck. If the
source of finger pain is diagnosed as entrapment of the median
nerve, the patient may be referred for carpal tunnel surgery. If
the problem is identified as scalene entrapment of the brachial
plexus, the current treatment is surgical removal
("scalenectomy") of the anterior scalene and the first rib to
which the muscle is attached. Unfortunately, this barbaric surgery
usually causes more problems than it cures.
Where care,
consideration, and technical skill on the mat have failed, know
this pain pattern and how to treat it -- by treating the muscle
and its trigger points.
- Masseter > TMJ, tinnitus, "sinus", and
toothache.
For its size and weight, the masseter is the
strongest muscle in the body and its effects are not trivial. It refers pain to both upper and lower molar teeth,
causes TMJ dysfunction, earache and a "sinus" pain over the
eyebrow. Prozac and related anti-depressants such as Paxil
specifically cause tightness in this muscle.
If you grind
your teeth at night and wake with a headache, ask your doctor
about taking the medication during the daytime when you can be
more aware of clenching and tooth-grinding which tense the
masseter but also strain the temporalis . . .
- Temporalis > "Tension / sinus" headache, TMJ and
toothache in upper teeth.
Combine a head-forward position
with a pipe and long hours of playing the violin (see the scalene
pain pattern, above) and what do you get?
"Elementary!" cries Dr.
Watson. "Head pain, tooth pain, and extreme tooth sensitivity to
heat/cold and vibration."
You may wisely eschew "The Seven Percent
Solution" in favor of directions to massage the temples to relieve
tension headaches. But to make it more effective, notice the
location of the trigger points and their specific areas of pain.
Temporalis is remarkable for spoke-like lines of pain up into
the temple and down into the upper teeth. Follow these lines and
you will feel distinct taut bands. Massaging them may provide
temporary relief. But the best approach is to follow the taut
bands down to their trigger points located as shown near the
cheekbones and adjacent to the ears.
- Pterygoids > TMJ and "sinus" pain.
The
lateral pterygoids (at right) help to open and protrude the jaw.
These relatively weak muscles are easily strained in opposing the
powerful masseter and temporalis muscles that close the jaw. The
pterygoids commonly develop trigger points which in turn cause
pain and/or clicking in the TMJ joint. They may block drainage
from the maxillary sinus causing more still more pain.
They are
also linked to tinnitis, and cause lateral deviation on opening
the jaw. There may be entrapment of the buccal nerve causing
numbness / tingling in the cheek (see buccinator, below).
The
masseter muscle and medial pterygoid support the jaw like a sling.
Masseter is on the outside, medial pterygoid inside; together they
close the jaw. Medial pterygoids produce diffuse pain in the
mouth involving the floor of the nose, tongue, throat and hard
palate; pain below and behind the TMJ joint, pain and/or
stuffiness of the ear, difficulty swallowing, lateral deviation
and possibly pain on opening the jaw. They can also
entrap the lingual nerve producing the odd symptom of a
bitter, metallic taste in the mouth (which the patient may not
connect with other symptoms and may not report for fear of
being thought "crazy.")
- Buccinator > Cheek pain.
This muscle forms the wall of cheek and
mouth. It's the part of the cheek that puffs out when playing the
trumpet (for which it is named), blowing up balloons or stuffing
one's mouth too full.
Buccinator pain may appear suddenly
following dental/orthotic work. There are no entrapments by the
buccinator itself, but the lateral pterygoid can entrap the buccal
nerve which supplies the skin and mucous membrane in this area.
The muscle itself can cause local pain deep in the cheek while
chewing, commonly misdiagnosed as TMJ dysfunction.
- Digastric > Neck pain and and toothache in the
lower incisors.
The digastric assists the lateral pterygoid in
opening the jaw against the counterforce of the far more powerful
temporalis and masseter muscles. The upper portion can entrap the
external carotid artery and auricular artery decreasing blood flow
to the brain.
Strained by retrusion of the jaw (as in playing the clarinet or
similar wind instruments) or by holding a violin in place with the
chin. Commonly damaged in whiplash injuries in concert with other
neck muscles such as trapezius and splenius. Trigger points in the
anterior belly send pain to the four lower incisor teeth and the
alveolar ridge.
There may also be pain in the throat and tongue
and difficulty swallowing because of the relationship to the hyoid
bone. Trigger points in the posterior belly refer pain to the
upper sternocleidomastoid muscle, pain to the throat possibly as
far back as the occiput. There may also be difficulty swallowing
and a bothersome feeling of a persistant "lump" in the throat.
That "lump" may be the hyoid bone which, again, is not moving
properly.
- Orbicularis > Nose and cheek pain (shown with
zygomaticus, below).
A trigger point in orbicularis refers
pain along the eybrow, alongside the nose to the upper lip. There
may be visual disturbances and problems with "jumpy print" in
reading, along with droopy eyelid (ptosis).
- Zygomaticus > Nose, cheek, and forehead pain
(shown with orbicularis, below).
Orbicularis and zygomaticus are the only two muscles
that refer pain to the nose. Both patterns are commonly mistaken
for "sinus" pain but may be due to a blow to the eye or simply
smiling too long at the reception.
Zygomaticus can entrap blood
vessels that travel from cheek to nose and up to the forehead. The
resulting pain is not "sinus," it's a muscle cramp due to reduced
blood and oxygen supply -- but no less painful.
- Occipitofrontalis > Temporal and eye pain.
Trauma
to the scalp fascia or the occipitalis at the back of the skull
can transmit pain through the head and into the eye. Trauma
may include a blow to the back of the head, strain from a tight
ponytail or bun, or the weight of long, heavy hair. In one case I
know of, a man struck the top of his head on the corner of a
cabinet. Result: a slight puncture wound in the scalp, a brutal
pain in the eye.
Frontalis helps open the eyes, raises the
eyebrows, and wrinkles the forehead into "worry lines." It is
commonly used by biofeedback practitioners to monitor muscle
tension. Trauma to frontalis (whether a blow to the forehead or
habitual frowning) can cause severe frontal headache often
diagnosed as "migraine."
Frontalis is one of the muscles that
definitively proved the muscle-migraine connection. Botox
injections paralyzed the frontalis, eliminating "worry lines" but
they also had the surprising side effect of halting chronic
"migraines". Or maybe not so surprising, as frontalis entraps the
supraorbital nerve. The related corrugator supercilii (at the top
of the nose between the eyebrows) compresses branches of the
supraorbital nerve along with the supratrochlear nerve and
branches of the supraorbital nerve.
All of these are branches of
the trigeminal nerve which is heavily involved in migraine. You
can treat trigger points with great results -- or, avoid
compressing those muscles. Your frown may be giving you a
headache!
- Splenius Capitis > Occipital neuralgia and "word
processor headache".
Splenius capitis and splenius cervicis
(below) are almost always injured in auto accidents,
regardless of the direction of the blow. They are commonly injured
in "head rolling" movements in exercise classes, always strained
by head forward position and by computer use or other reasons for
sitting with head held forward and turned to the side. Splenius
capitis (shown below, right) typically causes a pain at the top
lateral side of head.
- Splenius Cervicis > Neck pain, eye pain, and
blurred vision.
Splenius cervicis (above, left) is strained in
all the ways as splenius capitis (above, right) but the results
are even more brutal. A trigger point high in the neck portion of
the muscle sends pain through the head from the occiput and
into the eye. Even without the pain, there may be blurred vision.
The lower trigger point refers pain to the angle of the neck.
Reading under a drafty air conditioner or riding a motorcycle with
head forward with a cold wind whipping around the edge of the
helmet is damaging to these muscles.
- Semispinalis Capitis > Head pain and occipital
neuralgia.
Injured in whiplash and involved in "tension" and
"cervicogenic" headache.
Semispinalis capitis is commonly injured in auto
accidents. You can injure it more slowly but just as effectively
with a chronic head-forward position. When tight, semispinalis may
entrap the greater occipital nerve which in turn causes numbness,
tingling and/or burning pain extending over the back of the head
to the top (vertex) of the head. It may be difficult to touch chin
to chest, and sufferers may be unable to bear the pain of laying
the back of the head on a pillow.
Relieve nerve pain with
cold. Relieve muscle pain with moist heat. In
either case, look for the origin of the pain, rarely the
spot where it hurts.
- Semispinalis Cervicis > Even more head pain.
This muscle typically produces a vague band of pain from
occiput along side of head to just behind orbit (similar to
suboccipital pain pattern).
- Longus Capitis, Longus Colli > Neck, ear, and eye
pain.
A pain in the neck, and surprisingly, pain in the eye
and ear and possibly the forehead (more "sinus" pain!) as well.
Almost always injured in whiplash.
- Multifidi and Rotatores > Basal skull pain, neck
pain and scapular pain.
This pain arises from the tiny muscles
that run between the individual vertebrae of the spine.
- Levator scapula > The "wry" or "stiff neck"
muscle.
Levator scapula is the Number One cause of "stiff" or
"wry" neck and the second most common shoulder girdle muscle
(trapezius is Number One) to have trigger points. Working with
trapezius, levator shrugs the shoulders and helps prevent forward
flexion of the neck, hence it is also damaged in whiplash
injuries.
In daily life, it is strained when a shoulder (or
shoulders) are chronically hunched, either in stress, or by
attempting to keep a strap from sliding off the shoulder,
especially when the muscle is cold or fatigued. Pain in the angle
of the neck and along the vertebral border of the scapula may be
so severe that patient cannot move the neck at all. In traffic that
may be a life-threatening condition.
- Suboccipitals > Temporal and eye pain.
The four pairs of suboccipital muscles cause deep aching pain
running in a band from the back of the head to the orbit of the
eye, possibly with balance problems and dizziness. One of these
(the rectus capitis superior minor) attaches directly to the dura
mater of the spinal cord. When traumatized it can produce odd
visual and neurological symptoms to the point of seizures.
Suboccipitals are commonly strained or hypertrophied in persons
who wear bifocals, children who watch TV lying with chin propped
on hands, and anyone who habitually holds the head in position
with chin up and neck flexed backward.
- Omohyoid > Head, neck, shoulder, and back
pain.
This small muscle (actually missing from many
anatomy books)can cause disabling pain and dysfunction. It's just
one of the several muscles that attaches to the hyoid bone. The
other end attaches to the scapula at the back of the shoulder.
Aside from the severe pain in shoulder, neck, and jaw (which often
appears after a bout of coughing or vomiting) there may also be
weakness and tingling down arm and fingers and symptoms of
thoracic outlet syndrome. Pain patterns may be confused with that
of the scalenes or levator scapula. An excellent article on The Omohyoideus
Syndrome is available online.
- Soleus > Heel and calf pain, sacral pain and
cheek (facial) pain.
An outstanding example of long-distance
pain referral from muscles. This muscle of the calf sends
pain to the calf and heel (commonly known "jogger's heel") -- but
there's more.
Pain from this
muscle also appears in the sacrum at the sacro-iliac joint and
then reappears in the face and jaw where it may fire off symptoms
of TMJ and toothache.
"But,"
you say, "migraine is vascular!" Indeed it is -- and the soleus is
the other end of the cardio-vascular system. It is known as "The
Second Heart" because its pumping action returns blood from the
lower extremities to the heart.
I have stopped many full-blown
migraines by working adductor and calf muscles. "But," you say,
"migraine is neurological!" Indeed it is -- and tightness and
restriction in soleus and the adductor magnus can cause serious
impingement of neurovascular structures including the femoral
nerve, femoral artery, and femoral vein (at the adductor hiatus of
the adductor magnus) and the posterior tibial nerve, vein, and
artery by the soleus. (The plantaris, a slip of the soleus muscle,
can also entrap the popliteal artery at the back of the knee.)
Entrapment can be so severe that the patient may lose deep tendon
reflexes. Short of that, it's no surprise that a sufferer might
have cold feet.
Upstream, entrapment by the adductors can be
brought on by failing to stretch out after using the thigh
machines at the gym and very commonly, by footwear. It may be
difficult to believe that shoes (whether you call them "cowboy
boots" or "high heels") may be causing your jaw and head pain, but
it is often true. Knee-high stockings with tight, constricting
bands will do the job and I have also seen a man who never had
headaches in his life until he caught some shrapnel in the calf.
Even worse can happen, however. When the soleus can no longer work
as "the second heart" due to inactivity or constriction, there can
be side effects far worse than migraine. Pooling and subsequent
clotting of blood in the lower extremities is involved in deep
vein thrombosis, also known as "airline thrombosis" due to the
consequences of a cramped seat and long periods of inactivity. The
condition is very real, but sadly mis-named. The condition arises
far more commonly from long hours of sitting at a desk than from
(relatively rare) airline travel.
