vagus nerve jugular foramen anatomy

The Jugular Foramen: The Crowded Skull Doorway Where Your Vagus Exits

Your vagus nerve leaves the skull through a narrow bony canal it shares with two other cranial nerves and a major vein. When that doorway gets crowded, throat, voice, swallowing, shoulder, and heart-rate symptoms tend to arrive together — and that clustering is a clue, not a coincidence.

vagus nerve myelin demyelination

Demyelination and Remyelination: How the Vagus Loses — and Rebuilds — Its Insulation

Nerve fibers are wrapped in a fatty insulation that lets signals sprint down the line. When that insulation is stripped from the vagus, signals slow and garble — and dysautonomia follows. The genuinely hopeful part is that peripheral nerves can re-wrap themselves.

visceral afferent interoception autonomic neuropathy

When the Body Goes Quiet: Losing Hunger, Fullness, and the Urge to Go

Everyone talks about bodies that scream too loudly — the racing hearts, the churning guts, the hypersensitivity. Almost no one talks about the opposite: bodies that go silent. Some people lose hunger, thirst, fullness, and the urge to empty the bladder or bowel entirely, and it is one of the most disorienting symptoms in all of dysautonomia.

Your Autonomic Nervous System, Explained: A Plain-English Map of Sympathetic, Parasympathetic, and Vagal Tone

Almost every symptom people write to us about — the racing heart, the exhaustion that sleep does not fix, the gut that will not settle, the sense of being switched permanently "on" — traces back to...

Tired All the Time: Chronic Fatigue, ME/CFS, and the Vagal Energy Crisis

"I sleep eight hours and wake up feeling like I never slept." Fatigue is the single most common concern people bring to us, and it is also the most dismissed — brushed off as stress, poor sleep...

The Lump That Won't Swallow: Globus, Difficulty Swallowing, and the Vagus Nerve

"It feels like something is stuck in my throat, but nothing is there." "I have to think about swallowing now, and sometimes food catches." These two complaints show up again and again in our intake,...

Cold Hands, Cold Feet, and a Body That Won't Warm Up: Temperature Dysregulation and the Autonomic Nervous System

"My hands and feet are always freezing, even in a warm room." "I run hot and cold with no pattern, and I sweat when I shouldn't." Temperature complaints rarely get taken seriously on their own, but...

Air Hunger: Why You Can't Get a Full Breath When Your Oxygen Is Perfectly Fine

"I keep trying to take a deep breath, but it never feels like it lands." "I feel like I'm not getting enough air, so I yawn and sigh constantly — but my oxygen is normal." This symptom is deeply...

The Pelvic Floor Won't Relax: Chronic Pelvic Tension, Pain, and the Vagus–Sacral Connection

Pelvic floor problems are among the most under-discussed concerns people bring to us — pelvic pain, pressure, urinary urgency, painful sex, constipation, a sense of never fully emptying. People are...

The Three Faces of POTS: A Clinical Map of Hyperadrenergic, Neuropathic, and Hypovolemic Subtypes

POTS is one diagnosis with at least three distinct physiologies. Treating them as one condition is one of the most common reasons patients stay sick. The subtype determines the protocol.

vagus nerve internal vibrations tremor

Internal Vibrations and Body Buzzing: The Symptom That Confuses Every Clinician

Patients describe a humming, buzzing, or vibrating sensation that no one else can feel. It is real, it has identifiable mechanisms, and it is increasingly tied to dysautonomia, small fiber neuropathy, and mast cell activation rather than psychiatric causes.

Cervical Instability and Vagal Compression: The Hidden Structural Driver of Dysautonomia

A 2025 Frontiers in Neurology paper coined the term "cervicovagopathy" — vagus nerve dysfunction with a structural etiology in the upper cervical spine. For some dysautonomia patients, the autonomic problem is downstream of a mechanical one.

vagus nerve nausea gastroparesis

Chronic Nausea: When the Vagus Nerve Loses Its Grip on the Gut

Persistent nausea without a clear surgical or pharmacological cause is most often a vagal motility problem — and recent open-label studies of non-invasive vagus nerve stimulation in gastroparesis are now showing measurable improvement in symptoms and gastric emptying.

Chronic Dizziness Without a Diagnosis: PPPD and the Vestibulo-Autonomic Link

When the workup is "normal" but the dizziness persists, the answer is often PPPD — a chronic functional vestibular disorder driven by a brain stuck in postural threat detection, with autonomic and vagal dysregulation as the engine.

The Hypermobility Trifecta: hEDS, POTS, and MCAS — Why the Vagus Nerve Is the Bridge

Hypermobile EDS, POTS, and MCAS travel together in a way that purely structural or purely immune models cannot explain. The bridge that ties all three together is autonomic — and the vagus nerve is the central player.

vagus nerve cirs mold

Mold Toxicity, CIRS, and the Autonomic Collapse: Why the Vagus Goes Silent

Biotoxin illness produces a measurable autonomic phenotype — low HRV, orthostatic instability, and chronic vagal underactivation — that explains why so many CIRS patients fail to recover even after exposure ends.

MCAS and the Vagal Brake: Why Mast Cells Need a Quiet Nervous System

Mast cells are wired into the autonomic nervous system. When the vagal brake fails, mast cells become reactive — and the cholinergic anti-inflammatory pathway emerges as one of the most underused tools in MCAS care.

Dysautonomia and the Vagus Nerve: A Practical Guide

Dysautonomia is a confusing diagnosis with overlapping symptoms — racing heart, dizziness, GI trouble, brain fog. Here’s how to think about it through the vagus nerve, and what helps.

Low Blood Pressure and Vasovagal Symptoms: The Other Side of Vagal Imbalance

Most articles talk about strengthening the vagus nerve. But sometimes vagal tone is too high, too quickly — leading to fainting, dizziness, and dropping blood pressure. Here’s the other half of the story.

Long COVID, Chronic Fatigue, and Post-Viral Vagal Dysfunction

Many of the strangest, most disabling symptoms of long COVID and chronic fatigue point to a single common pathway — a vagus nerve that hasn’t recovered from a viral hit. Here’s what helps.
