“Your tests are normal” should never be translated into “your symptoms are not real.”

It should mean the tests did not detect the type or degree of dysfunction they were designed to detect.

That distinction is where many complex nerve cases get lost.

A standard workup is excellent at identifying fixed lesions, large-fiber damage, denervation, major structural compression, and other serious pathology. It is much less suited to answering questions like:

Does the nerve move normally through its entire pathway?

Does it become symptomatic only after repetition, load, or a specific position?

Are several smaller restrictions creating one cumulative problem?

Is the nerve’s recovery capacity being reduced by sleep, inflammation, metabolic health, nutrition, or previous injury?

This is why I do not stop at the body part that hurts or the test that came back normal. I look at the whole nerve pathway, the patient’s functional threshold, and what changes when the suspected interfaces are treated and immediately retested.

That test-retest process matters. It tells us whether the system is mechanically modifiable, whether the treatment target makes sense, and whether we should continue, change direction, investigate further, or refer out.

I am Dr. Sina Yeganeh, chiropractor and global complex case consultant. I work with patients whose symptoms have outgrown single-region explanations and whose conventional workups have not explained why function keeps failing.

My newest Movability Masterclass article on Substack is:

“Normal EMG. Normal MRI. Still Numb: Why Double Crush Syndrome Misses Multisite Nerve Dysfunction.”

Inside, I break down the physiology of nerve glide, blood flow, fascial interfaces, mechanotransduction, tissue remodelling, and why double crush is often too narrow. I also walk through a real clinical case and the pivot points that changed the outcome, without reducing the story to one tunnel or one treatment.

The full Root Cause Breakdown is linked in my bio.

At Movability, this is why our complex case assessments examine the whole pathway, retest function, and let the physiology determine the next step.

You were told your cerebral venous sinus is narrow.

But were you ever told why?

For many people, that is exactly where the investigation stops. They are shown an MRV, given a label, and left without an explanation for what narrowed it, whether it is driving their symptoms, or what should be investigated next.

One clinician says it is congenital and irrelevant. Another treats the narrowing as the entire disease.

But the same image can represent completely different physiology.

It may be a normal anatomical variant. It may only look narrow because of slow or turbulent flow. It may be collapsing under elevated pressure around the brain. It may contain a clot, scar, arachnoid granulation, or web. The resistance may even sit farther downstream in the jugular or central venous system.

Sometimes the sinus is the cause.
Sometimes it is the consequence.
Sometimes it starts as the consequence, then becomes an amplifier that helps sustain the pressure problem.
Sometimes it is incidental.

The scan may be showing where the system gave way, not where the problem began.

That distinction changes everything.

The question is not only, “How narrow is it?”

The better questions are:

What force narrowed it?
What created that force?
Is it functionally significant?
Is it fixed or potentially reversible?
What should change when the real driver is treated?

You are not unreasonable for wanting more than a label. A finding on a scan should open the investigation, not close it.

My new Movability Masterclass article is:

“You Were Told Your Cerebral Venous Sinus Is Narrow. The Investigation Should Not Stop There.”

Inside, I break down the root-cause physiology, how to distinguish transient pressure-dependent collapse from fixed obstruction, when narrowing may reverse, what imaging and pressure testing can tell us, where investigations commonly stop too early, and the seven-step framework I use for these cases.

The full Root Cause Breakdown is now live on Substack.

Movability Masterclass is for clinicians and curious minds who refuse surface explanations and want to understand what is driving complex symptoms.

Allow me to re-introduce myself.

I’m Dr. Sina Yeganeh, chiropractor, global complex case consultant, and cofounder of Movability.

My work is centred on complex chronic pain and nerve-related cases, especially the ones that do not fit neatly into a diagnosis, a body part, or a single discipline.

The cases where symptoms move, findings conflict, imaging tells only part of the story, and people have seen multiple providers without anyone stepping back to connect the full picture.

Complexity is not at the edge of my work. It is the centre of it. These are the cases I love.

I’ve had the privilege of working alongside doctors and clinicians around the world whose thinking has challenged, shaped, and sharpened my own.

Those experiences have influenced the way I approach difficult cases: question assumptions, recognize patterns across systems, and never reduce a person to one scan, one structure, or one symptom.

That philosophy is also why we built Movability the way we did.

Complex care should not be siloed. The difference is not simply having multiple disciplines under one roof. It is how our team communicates, collaborates, and brings different clinical perspectives into the same conversation.

A collection of services is not the same as integrated care. Our goal is to use the full potential of a team-based model to make better sense of complexity and create a more coordinated path forward.

For the next couple of hours only, I’m opening a Q&A specifically about NERVE PAIN.

Burning, tingling, numbness, electric or shooting pain, weakness, sciatica-like symptoms, or symptoms that feel difficult to explain.

A few boundaries before you ask:

This is for general education only. I cannot diagnose you, assess your individual case, or provide personal medical advice through Instagram.

Please keep questions focused on nerve pain, and do not post private health information or imaging.

For clinic, booking, pricing, insurance, scheduling, or administrative questions, please visit our website or contact the clinic. Our team will be happy to help.

I’ll answer as many questions as I can before the Q&A closes.

Ask below. Let’s connect some dots.

The psychiatric symptom may be the last event in the chain.

That is what medicine keeps missing about PMDD.

When bloating, reflux, broken sleep, migraine, flushing, palpitations, and sensory overload rise before rage or despair, I do not see a collection of unrelated diagnoses.

I see a sequence.

And in complex physiology, sequence is evidence.

Histamine matters because it is not only an allergy mediator. In the brain, it is a neurotransmitter that helps regulate wakefulness, arousal, attention, and sensory gain. In the body, mast-cell histamine affects the gut, blood vessels, airways, skin, and nerves.

Those histamine systems are not identical, but they are part of a body that is constantly communicating.

This is why women reporting major PMDD changes after H1 and H2 blockers deserve more than dismissal.

Not because they have proven a treatment.

Because their responses may have exposed a convergence point.

If altering histamine signalling shifts mood, sleep, migraine, digestion, flushing, and autonomic symptoms together, the most interesting question is not:

“Which pill worked?”

It is:

“What network did we just expose?”

This is the work I do in complex cases. I reconstruct physiology in motion. I look for the earliest shift, the biological timing, the systems that move together, and the difference between a trigger, an amplifier, and a maintainer.

The hormone transition may be the trigger.

The gut-immune load may be the amplifier.

Sleep loss and migraine may become maintainers.

Histamine may be one of the bridges.

This is not a story about “high histamine” or the gut simply causing PMDD.

It is a more sophisticated possibility:

A hormonally sensitive nervous system may be pushed across a threshold by immune, gut, vascular, sensory, and autonomic load.

The mood symptom may be the final expression of a whole-body state.

That is a very different way to read the case.

I unpack the full model, evidence, sequencing logic, and clinical case in Movability Masterclass on Substack.

A complex case does not mean a difficult person. Often, it means the explanation so far has been too small.

Movability was built from moments that forced us to look again: a diagnosis that did not explain the whole story, a plan that stopped working, and a person who had told their story repeatedly but never felt fully understood.

Those moments shaped our standards.

We learned that good care is not about becoming attached to the first answer. It is about staying curious enough to earn a better one. That means listening before assuming, questioning a label when it no longer fits, and using a systems-based approach to understand the pattern as a whole, not only where it becomes visible.

Not complexity for its own sake. The goal is clarity.

A symptom may be felt in one place without being explained by that place alone. The place that hurts still matters, but it may not tell the whole story.

Our role is not to force every case into the same explanation, or promise one hidden cause behind every symptom. It is to ask better questions, make the reasoning clear, involve you in the process, and change course when new information changes the picture.

Credibility does not come from certainty alone. It comes from reasoning that can be explained, questioned, and revised as the evidence changes.

When you have lived with a problem that has never been fully explained, clarity is not just reassuring. It gives you somewhere to begin. It restores direction.

Perhaps that is why people from around the world keep finding their way to Movability.

Beneath many of those stories is the same question:

What happens when the usual answers are no longer enough?

That question can begin a different kind of search. Not for another quick fix, but for a clearer understanding of the pattern, how its parts relate, and what can meaningfully change.

Movability is built around attention, collaboration, and the belief that complex problems rarely fit a standard script.

The difficult moments did not make us cynical. They made us more deliberate about the kind of clinic we wanted to become.

We did not build Movability simply to treat more people.

We built it to see people more completely.

Her neck looked like the problem. I did not touch it.

She came in with left-sided neck and shoulder tightness. The tension climbed into the base of her skull and contributed to head and facial pain.

When I tested her neck, bending to the right was restricted because the left side would not release.

But the most important finding was not in her neck.

After a stressful couple of weeks, her left TMJ and chewing muscles were tighter than the right, matching her neck tension and headache.

I treated only her left jaw with soft-tissue work, neural techniques, and joint mobilization. I avoided her neck and shoulder to create a clinical test.

Then we retested.

Her right side-bending improved dramatically. The left-sided guarding dropped, and her neck moved more freely without being touched.

How can TMJ treatment change neck range of motion?

The jaw and upper neck are not isolated systems. Sensory information from the teeth, TMJ, and chewing muscles enters the trigeminal system, where it interacts with input from the upper cervical nerves.

When the jaw feels painful or restricted, the nervous system may increase jaw and neck co-contraction. A “tight” neck muscle may partly be a protective response to information coming from the jaw.

As a global complex case consultant, I’ve been fortunate to collaborate with dentists, airway specialists, and TMJ specialists worldwide. Those cases reinforced the need to view the jaw, bite, airway, head, and neck as one connected system.

Change the input, and the output can change.

This does not mean every neck problem comes from the TMJ or that every patient needs bite correction. It means the jaw was a meaningful contributor to this patient’s pattern.

The painful area and the primary driver are not always the same place.

Save this for the next time neck tension, headaches, jaw tightness, clenching, dental work, or bite changes appear together. Share it with someone who keeps treating the neck without checking the jaw.

They didn’t become a different person. Their body had been living in “agita.”

Their family says, “You’re not yourself.”

A calm person becomes wired, anxious, irritable and short-fused. They clench their jaw, wake with headaches, battle TMJ pain, notice tinnitus and may see blood pressure rise when pain and fight-or-flight take over. Gastritis, reflux, gas and upper-abdominal pressure can feel like palpitations or chest discomfort. Every sensation triggers another alarm until they stop trusting their body.

Too often, they hear, “It’s just stress.”

Then we test, and there it is: H. pylori.

Sometimes it appears on a GI-MAP qPCR stool panel. But the result is only one piece. We listen to the timeline and what the patient has been trying to tell us.

H. pylori lives in the stomach, but the fallout can be felt throughout the gut. Inflammation, altered digestion, poor sleep, gut-brain signalling and a nervous system stuck in survival mode can ripple far beyond it.

Eradication often requires antibiotics and acid suppression. That may eliminate the infection while causing nausea, bloating, altered stools, food intolerance and microbiome disruption.

That is why we never confuse eradication with recovery.

A negative test tells us the infection is gone. It does not tell us whether the stomach lining has healed, digestion is normal and the gut ecosystem has recovered.

This is where systems-based care matters.

We confirm eradication. We assess the stomach and whole GI tract. We review medications, food tolerance, bowel function, nutrition, sleep, jaw tension, stress physiology and microbiome findings. Then we rebuild brick by brick, with a plan designed for the person in front of us, not a random pile of supplements.

Then they say, “I feel like myself again.”

Sometimes the personality never changed. Their body sounded the alarm for so long that survival mode became normal.

If someone you know started acting like Tony Soprano when their gut fell apart, send them this. The “agita” may not be who they are. It may be what H. pylori, gastritis and a nervous system stuck on high alert have done to them.

Chest pain requires prompt medical evaluation.

Fibromuscular dysplasia, or FMD, is a disorder of the artery wall. It is not cholesterol plaque or vasculitis. In the neck, it affects the carotid and vertebral arteries and may involve narrowing, tortuosity, aneurysm, dissection, or a “string of beads” appearance.

Cervicocephalic FMD does not always look vascular at first.

The headache is labelled migraine.
The dizziness is treated as vestibular.
The jaw and neck pain are treated mechanically.
The pulsatile tinnitus is investigated elsewhere.

Each finding may be real, but the larger pattern can still be missed.

Then the diagnosis is made, sometimes after a dissection, and the patient is failed again. They get imaging, medication, surveillance, or vague restrictions, but no practical plan for movement, exercise, other pain, or urgent symptom changes.

Not everything is caused by FMD. Patients can still have migraine, mechanical pain, sleep apnea, dysautonomia, deconditioning, or an intracranial-pressure disorder.

But every treatment decision must account for FMD safety.

That means medical surveillance, blood-pressure management, and monitoring for dissections, aneurysms, neurological changes, and disease elsewhere.

It also means reducing avoidable vascular stress and rebuilding function.

An emerging hypothesis suggests remodelling may involve the outer arterial wall, where sympathetic nerves, mast cells, fibroblasts, and TGF-beta signalling interact.

The artery may not only be wearing out.

It may be repeatedly misrepairing.

This is unproven. It does not mean stress or MCAS causes FMD. It suggests that autonomic load, blood-pressure variability, sleep, mechanical exposure, and connective-tissue biology deserve attention alongside medical care.

The goal is to reduce risk, coordinate care, treat other pain safely, and help the patient become stronger without making them feel fragile.

The highest-risk diagnosis should set the safety boundaries. It should not erase the rest of the patient.

Chin tucks are not harmless.

Not for everyone.

They are treated like a basic neck exercise:

Forward head posture? Do chin tucks.
Neck pain? Do chin tucks.

But as a global complex case consultant, I see the same pattern:

Patients try them online, or they are prescribed in rehab, and instead of improving, they flare.

Head pressure.
Dizziness.
Pulsatile tinnitus.
Visual changes.
Throat tightness.
Arm heaviness.
“My head feels too heavy.”

Then they are told to keep pushing because the muscles are weak.

But that is not always weakness.

Sometimes the exercise challenged the wrong system at the wrong time.

A chin tuck is not just a posture cue.

It changes the relationship between the skull, C1, C2, CSF dynamics, venous drainage, the jaw, throat, and airway.

In simple neck pain, it may help.

But with CCI, Chiari, IIH, venous congestion, a CSF leak, hypermobility, concussion, vestibular migraine, TMJ, or airway issues, the same movement can become a stress test.

Same movement.
Different physiology.

This is why “just fix your posture” can miss the point.

Sometimes forward head posture is not the root problem. It may be the position the body found to breathe, swallow, stabilize vision, manage pressure, reduce neural tension, or protect the upper cervical spine.

Force that person into a chin tuck before understanding why their body chose that position, and you may remove the compensation before identifying the cause.

That is how a posture drill becomes a three-day flare.

Chin tucks are not evil.

They have to be earned.

If they trigger head pressure, dizziness, visual changes, tinnitus, swallowing changes, arm heaviness, neurological symptoms, or that heavy-head feeling, do not ignore it.

That response is clinical information.

I broke down the anatomy, physiology, red flags, and sequencing logic in my Substack article:

“When Chin Tucks Make Patients Worse: CCI, Chiari, IIH, and the Skull-Neck Pressure Pattern.”

Read it inside Movability Masterclass. LINK IN BIO.

This is the root cause work we do at Movability.

Save and share this with someone who was told to push through an exercise that made them worse.

Not every pain at the back of the head is occipital neuralgia.

Location alone is not a diagnosis.

True occipital neuralgia is a specific nerve-pain pattern involving the greater, lesser, or third occipital nerve. It is classically severe, brief, shooting, stabbing, or sharp, and may come with scalp sensitivity, tenderness over the nerve path, and temporary relief after an occipital nerve block.

But several things can look similar:
• Cervicogenic headache from cervical joints, discs, or neck soft tissues
• Migraine referring pain into the occipital region
• Suboccipital or upper-trap trigger points
• Upper cervical nerve root irritation
• C2-3 facet or third occipital nerve referral
• Post-whiplash headache
• TMJ, clenching, or bruxism referral
• Shingles or post-herpetic neuralgia

The better question is not just:
“Is this ON?”

It is:
“What is irritating the system?”

More neck-driven clues: pain changes with posture, neck rotation, extension, sustained desk position, loading, palpation, or reduced cervical range of motion.

More migraine-driven clues: attacks lasting hours, nausea, light/sound sensitivity, throbbing, activity sensitivity, visual symptoms, or sleep, stress, hormone, food, dehydration, or weather triggers.

More nerve-like clues: brief zaps, shocks, stabbing pain, scalp pain with light touch, pain along the occipital nerve path, and tenderness where the nerve exits near the base of the skull.

Must-not-miss patterns:
• Cough, strain, or Valsalva-triggered occipital headache, consider Chiari or posterior fossa pressure patterns
• Worse upright and better lying down, consider CSF pressure/leak patterns
• Vision changes, pulsatile tinnitus, or papilledema, consider intracranial pressure
• Sudden severe head/neck pain or neurological symptoms, seek urgent care
• New headache after 50, scalp tenderness, or jaw pain with chewing, consider giant cell arteritis
• Fever, cancer history, immune suppression, trauma, or progressive worsening, get assessed

Occipital neuralgia is real. But not every occipital headache is ON.

Assess the pattern. Identify the driver. Refer when red flags show up.
