For years I treated my trigeminal neuralgia as a face problem. It lived in my jaw, my cheek, my sinus — so naturally that is where I focused. I saw dentists, tried medications, managed flares as they came. The idea that my digestive system had anything to do with nerve pain in my face honestly would have sounded ridiculous to me back then.
Then acupuncture changed everything slowly overtime. The pain started responding in ways it never had before and I began paying attention to what my TCM doctor had been trying to show me all along.
What Is Trigeminal Neuralgia
The trigeminal nerve is one of the largest cranial nerves in the body. It has three branches that spread across the face — covering the forehead, the cheek and mid face, and the lower jaw. When this nerve becomes irritated or inflamed it can cause anything from a dull persistent ache to sharp electric shock like pain along those pathways. Chewing, talking, even a light touch can trigger it. For many people it is one of the most disruptive and frustrating pain conditions to manage because it shows up right in the middle of everyday life.
Western medicine typically addresses it through medication, nerve blocks, or surgery depending on severity. But what happens when your scans come back clear? No compression, nothing obvious to point to. How do you explain it then? Even doctors don’t always have a clear answer. What it doesn’t always get into is why the nerve becomes irritated in the first place — and that’s where TCM offers a different way of looking at it.
*Chronic pain affects about 1 in 5 adults in Canada, which shows how common it is to be dealing with something ongoing, even if it looks different for everyone.*
What My TCM Doctor Showed Me
My TCM doctor explained the connection using the stomach meridian pathway and once I saw it I could not unsee it.
In TCM the body is mapped by a system of meridians — channels through which Qi or vital energy flows. Each meridian is associated with a specific organ system and follows a defined pathway through the body. The Stomach meridian is one of the longest and most important of these pathways and its route through the face is what makes it directly relevant to trigeminal neuralgia.
The Stomach meridian begins just below the eye at a point called ST1, travels down through the cheek, curves along the upper jaw and mouth, moves through the lower jaw and chin, and then descends down through the throat, chest, and abdomen all the way to the feet. Looking at that pathway on a diagram it becomes immediately clear — the Stomach meridian runs directly through the same facial territory that the trigeminal nerve covers. The cheek, the upper jaw, the lower jaw, the area around the mouth — these are shared pathways.
When there is imbalance in the Stomach meridian — whether that is Heat, stagnation, or deficiency — that pathology does not stay in the stomach — it travels. And because this pathway runs through the face, it can show up as pain, inflammation, or nerve irritation along that same area.
The Spleen and Stomach
In TCM the Stomach never works alone. It is always paired with the Spleen and together these two organ systems form the foundation of digestion and energy production in the body.
The Stomach receives food and begins the process of breaking it down. The Spleen then transforms those nutrients and transports them as usable energy throughout the body. When this partnership is functioning well the body is well nourished, energy is steady, and the meridian pathways flow freely.
When this partnership is weakened things start to go wrong in ways that can seem completely unrelated to digestion on the surface. Poor diet, irregular meal times, eating under stress, too many cold or raw foods, excess sugar and refined carbohydrates — all of these place strain on the Spleen and Stomach system. From a TCM perspective, that can lead to things like Dampness, Heat, or stagnation (think of this as internal sluggishness or inflammation), building up in the meridian which then travels upward through its pathway into the face.
In my case, years of not paying attention to what or how I was eating, combined with significant stress, had likely been creating the conditions for that upward travelling Heat and stagnation long before my TN symptoms became serious. I just didn’t have a way to connect those dots until TCM gave me one.
When Acupuncture Started to Make a Difference
I will be honest — I did not start acupuncture because I believed in the meridian theory. I started because the pain was bad enough that I was willing to try something different and I was determined to find the root cause.
What I did not expect was for it to work as consistently as it did. After treatment, the facial pain would ease enough to feel manageable. And it was not just needles along my face — it was my arms, legs, stomach, all over. That was the first thing that surprised me. Acupuncture was not just addressing the pain site, it was working on the body as a whole. Over time I began to understand why. My TCM doctor was treating the Stomach and Spleen meridian points throughout the body and those points were directly influencing what I felt in my face. That experience was what finally made sense to me and led me to study TCM.
What the Research Suggests
While TCM and Western medicine explain things differently, there is some overlap that’s starting to show up in research.
We know the gut and brain are constantly communicating through what’s often called the gut–brain axis. It’s not a one-way system — what’s happening in the gut can influence the nervous system, and vice versa. About 90% of serotonin is produced in the gut, which gives you a sense of how connected these systems are.
There’s also research showing that ongoing stress can affect how we experience pain — basically lowering the threshold so the same trigger can feel more intense when the body is already under pressure. And there’s growing interest in how inflammation in the body may influence nerve signalling. It doesn’t explain everything, but it starts to show how different systems can affect each other in ways we don’t always expect.
The vagus nerve is one of the main communication pathways between the gut and the brain. It originates in the brainstem, close to where the trigeminal nerve sits, and carries signals back and forth between the brain and the body.
For me, the easiest way to understand it is this — when your system is already dealing with stress or imbalance, everything can feel a bit more heightened. So something small can start to feel like a lot. Research on how all of this connects to facial nerve pain is still ongoing. But it does point to the idea that what’s happening in one part of the body can affect another — even when it’s not obvious at first.
What Changed When I Started Taking Digestive Health Seriously
Once I understood the connection I started approaching my TN management very differently. Instead of only focusing on the face I really started paying attention to what was happening in my gut. Some of the specific changes that made a difference:
Eating warm cooked meals rather than cold or raw foods — in TCM cold foods directly weaken Spleen Yang which is the warming digestive energy that keeps the system functioning properly, I often have millet congee in the mornings and I add a bit more water so I sip the water throughout the day. It helps to warm and nourish the Spleen/Stomach.
Eating regularly — skipping meals or eating at irregular times stresses the Stomach meridian and can contribute to the kind of Qi deficiency that allows pathology to travel upward.
Reducing sugar and refined carbohydrates — these generate Dampness and Heat in the Stomach and Spleen system, exactly the kind of internal environment that can aggravate the meridian pathway running through the face.
Managing stress around mealtimes — in TCM the Stomach is particularly sensitive to emotional stress. Eating while anxious, rushed, or upset directly affects the Spleen and Stomach function. This one was harder to change but overtime, it made a noticeable difference.
Supporting gut health with fermented foods and probiotics — a healthier gut microbiome reduces the overall inflammatory load on the body which in turn reduces the conditions that aggravate nerve pain.
Acupuncture regularly — not just during flares but as ongoing maintenance to keep the Stomach and Spleen meridians balanced and flowing freely.
None of these changes eliminated my TN entirely. But together they reduced the frequency and intensity of flares in a way that nothing else had managed before. And understanding the reason why made it much easier to stay consistent with them.
I went into remission for seven years. Seven years of real relief. When it came back it was not random — stress and perimenopause had created the perfect storm for it to return. But that is a whole other conversation and honestly a whole other post.
That seven-year remission is something I think about a lot. It showed me that TN isn’t always as unpredictable or out of our hands as it can feel. Our overall health matters. What we eat matters. How we manage stress matters. How we support our hormones and digestion matters. We don’t have full control — I want to be real about that — but we do have more influence than we’re usually told. Because in my experience being handed a prescription and sent home with no further explanation is not good enough. Our bodies are connected systems and sometimes the answer to what is happening in one place starts somewhere else entirely. For me it started in my gut.
What I Want You to Take Away From This
If you have trigeminal neuralgia or any kind of chronic facial nerve pain and nobody has ever asked you about your digestion — it might be worth asking the question yourself.
The connection between the Stomach meridian and the trigeminal nerve pathway is one of those things in TCM that seems surprising until you see the anatomy and then it seems almost obvious. The meridian literally travels through the face. Of course what happens in that channel affects what you feel there.
I am not saying digestive health is the only factor in trigeminal neuralgia. It is complex and every person’s picture is different. But in my experience and through what I have learned from my TCM doctor over the years — keeping the Spleen and Stomach happy has been one of the most meaningful things I have done for my facial nerve pain.
It took me a while to believe it. But the body has a way of making things clear when you start paying attention.
Simply Salt and Soul
The Salt (The Science): Here is something worth knowing — the trigeminal nerve and the vagus nerve both originate in the brainstem and sit in very close proximity to each other. The vagus nerve is the main communication link between the gut and the brain, with signals moving between them all the time. When the digestive system is under stress — from poor diet, inflammation, or dysbiosis — those signals travel upward through the vagus nerve into an already busy brainstem neighbourhood. For someone with trigeminal neuralgia that proximity matters. It’s not a stretch to think that ongoing gut inflammation could make that area more sensitive over time. The systems are that closely connected.
The Soul (The Wellness): I still remember lying on that treatment table wondering what a needle in my leg had to do with pain in my jaw. I did not have an answer then. What I did have was the quiet experience of the pain easing after each session in a way nothing else had managed. That was enough to keep me coming back. And the more I learned the more it all made sense — the connection between what I was eating, how my digestion was functioning, and what I was feeling in my face. Understanding that link did not just help me manage the pain better. It changed how I take care of myself entirely.
Just a little note before you go — everything I have shared here is based on my own personal experience and what I have learned through my own TCM journey. Everyone’s body is different and what has worked for me may not be the right path for everyone. This post is not medical advice and I always encourage you to work with a qualified practitioner — whether TCM, western, or both — to find what works best for your unique situation. I am simply sharing what has made a difference in my life in the hope that it might spark something useful in yours.
