Chronic Lower Back Pain

 

How One Client’s Lingual Nerve Trauma Unlocked a Breakthrough in Anxiety and Recovery

Christian was only 23.

A high-performing college grad with a sharp mind, a passion for making animated movies, and a pretty solid sense of humor (on good days).

He wasn’t the type to complain.

He pushed through discomfort.

He kept his word.

And if he was struggling, you’d never know it, unless you saw the tightness in his jaw or the way his shoulders never really relaxed, even when he smiled.

That all changed after the surgery.

It was supposed to be a routine dental procedure. Nothing extraordinary. But something went wrong—unexpected, rare, and invisible to most: the surgeon accidentally severed Christian’s lingual nerve.

They told him not to worry. They grafted it. They said the nerve reconnected perfectly. That his tongue function would return.

But Christian didn’t feel "perfect."

He didn’t feel right at all.

 

 

When Sensory Mismatch Triggers a System-wide Alarm

On paper, the surgery was a success. But Christian’s anxiety and anger were telling his parents a different story. 

The tongue, the front two-thirds of it, to be exact, just didn’t feel normal. Taste was dulled.

In his words, it felt floppy.

And the more he tried to “move past it,” the worse his emotional regulation got. 

He became angry. Anxious. Obsessive.

He couldn’t stop thinking about it.

Couldn’t stop thinking about it.

The nerve might’ve reconnected, but in Christian’s nervous system, this small sliver of oral territory had become a war zone.

And here’s what most providers don’t realize:


A threat in the mouth isn't just a mouth issue.

The lingual nerve is a sensory branch of the mandibular division of the trigeminal nerve (cranial nerve V3).

It plays a key role in:

  • Somatosensory input from the anterior tongue

  • Taste (via chorda tympani, from cranial nerve VII)

  • Speech, swallowing, jaw coordination, and even breath control

So when that nerve is damaged, even if technically “repaired”, the entire brainstem network can interpret it as a persistent threat.

That’s what was happening to Christian.

And it was wrecking his nervous system and his ability to function in school.

 

 

From Oral Trauma to Whole-System Shutdown

Within weeks of the surgery, Christian’s life started shrinking.

  • Foods felt wrong in his mouth

  • Speech became self-conscious

  • Breathing felt shallow and effortful

  • Social interactions made his anxiety spike

Worse, every doctor told him the same thing: “You’re fine. It’s healed.”

But inside his nervous system, the message was: “We are not fine.”

He became hypervigilant.

Furious.

He hated the feeling of his tongue.

He hated that no one believed him.

And he hated himself for not being able to “get over it.”

 

 

The Brain Doesn’t Care About Perfect Scans. It Cares About Safety.

By the time Christian found us, he was exhausted. He’d read about the vagus nerve and trauma, but it didn’t quite explain what he was feeling.

He wasn’t looking for a supplement. He didn’t want to meditate his way out of a medical error.

What he needed was for someone to believe him and to teach his brain that his tongue wasn’t dangerous anymore.

That’s where applied neurology came in.

 

 

First, We Had to Understand the Lingual Nerve’s Unique Threat Profile

The lingual nerve is notoriously sensitive.

After injury, its activation threshold drops, meaning even light pressure can feel like a lightning strike.

 

But what makes it especially tricky is its overlapping cranial circuitry:

  • It connects to cranial nerves V (trigeminal), VII (facial), IX (glossopharyngeal), and X (vagus)

  • It affects both sensory input (what we feel) and motor behavior (how we move, eat, breathe, and speak)

  • It resides in one of the most protected, innervated zones of the entire body: the oral cavity

 

So even after surgical repair, the brain can still tag it as unsafe, leading to:

  • Overclenching of the jaw

  • Shallow breathing or altered vagal tone

  • Emotional flashbacks or shutdown

  • System-wide threat and dysregulation

Our goal wasn’t just to “stimulate” the nerve.

It was to help Christian’s brain trust it again.

 

 

Building the Jaw–Tongue–Breath Axis:

A Nervous System Map Back to Safety

We started small.

In applied neurology, we know that reintroducing compromised inputs must follow this rule:

“Low threat, high control.”
That means slow, precise, and always paired with grounding work.

Here’s how we helped Christian rebuild safety, step by step.

 

 

Week 1–2: Gently Saying Hello to the Tongue Again

1. Tongue Circles

Christian began by tracing slow circles inside his mouth with the tip of his tongue.

Clockwise.

Then counterclockwise.

Why it worked:
This re-mapped proprioception and gently engaged the lingual nerve without spiking the threat alarm.

5–10 reps per direction, 1–2x daily.

 

 

 2. Tongue Press + Breath

He pressed the tongue to the roof of his mouth, inhaled through the nose, and exhaled slowly through pursed lips.

Sometimes we added a light hum.

Why it worked:
This built a positive, co-regulated association between the tongue and the parasympathetic system (vagus nerve).

3 rounds of 5 breaths, in stacked seated posture.

 

 

Week 3: Layering in Jaw Motion and Sensory Load

3. Jaw Circles with Anchored Tongue

With the tongue lightly resting on the roof of the mouth, Christian slowly circled the jaw—forward, side, down, and back.

Why it worked:
This rewired midbrain safety circuits and untangled compensatory jaw tension from the tongue’s motor map.

3 circles each direction with mirror feedback.

 

 

4. Light Tongue Resistance Training

Using a gloved finger, he gently pushed the tongue forward and sideways with less than 30% effort.

Why it worked:
This reintroduced load to deep motor units, strengthening the sensory-motor integration without overwhelming the nerve.

2–3 light presses per direction.

 

 

Weeks 4–6: Building Integration Across Systems

5. Vocal-Tongue Repatterning

Christian inhaled through the nose, hummed “Mmmm” or “Nnnn,” then opened into vowels like “Ahhhh” or “Oooo.”

Why it worked:
This activated cranial nerves V, VII, IX, X, and XII simultaneously—integrating tongue, voice, breath, and vagal tone.

3–5 cycles after breathwork and grounding.

 

 

But What About Overstimulation?

This was critical.

Because post-trauma, more input isn’t always better.

Overstimulating the lingual nerve can cause:

  • Jaw clenching or eye fatigue

  • Brain fog or emotional overwhelm

  • Pupil dilation or shallow breathing

  • Resurfacing of shame or shutdown responses

So every oral drill was immediately followed by grounding resets, such as:

 

 

Nervous System Grounding Tools We Used

 Wall Press

Light pressure through the arms into a wall while nose-breathing.
Why: Joint compression calms the midbrain.

Tactile Foot Mapping

Texture ball under the feet to enhance proprioceptive feedback.
Why: Brings awareness back to the whole body.

Floor Stack Breathing

Lying in 90/90 with low back grounded and tongue up during breath cycles.
Why: Stacked posture restores vagal tone and oral safety.

Peripheral Vision Drills

Arms in a wide field, fingers wiggling gently.
Why: Tectal activation signals “we’re safe” to the nervous system.

These weren't optional, they were essential for managing threat load.

 

 

Rewiring Perception, Reclaiming Power

Over time, Christian’s system began to shift.

  • His anxiety lessened

  • His jaw softened

  • His breathing deepened

  • His obsession with the tongue injury faded

But perhaps most importantly, he stopped hating himself.

Because what Christian learned through this work is what many of your clients may never hear:

"You're not broken. You're not crazy.
You're just living in a nervous system that’s trying to protect you.”

 

 

Lessons for Clinicians:

The Invisible Injury That Changes Everything

Christian’s case is more common than you think.

Whether it's dental trauma, chronic TMJ, or unresolved oral tension, the tongue is a high-threat, low-tolerance area.

And yet, it’s often overlooked in rehabilitation, pain therapy, or trauma work.

As clinicians and coaches, we must:

  1. Respect the complexity of the cranial nerves

  2. Understand the oral cavity’s threat load

  3. Pair reintroduction with grounding

  4. Assess and reassess using breath, balance, or mood, not just ROM

 

Tools You Can Use Right Now

If you suspect a client is stuck in oral trauma or jaw-based dysregulation, try this 3-step sequence:

1. Tongue Circles →

5 reps per direction

2. Wall Press or Grounded Feet Reset →

10–15 seconds

3. Tongue Press + Humming →

3–5 breaths

Then reassess:
Are they calmer?

Is their breath easier?

Do they feel more present?

Start here. Track changes. Layer slowly.

Because safety, not stimulation, is the real goal.

 

 

Reconnection is More Than Surgical

Christian’s nerve reconnected physically.

But that didn’t matter, until his brain believed it.

That’s the beauty of applied neurology:
It gives us tools to speak to the real operating system, the one that decides safety, pain, and performance.

And when we do that… healing becomes possible.

Even when every scan says, “You’re fine.”
