In October, when I was 39 years old, my life irrevocably changed.
For years before, I lived with inflammation in different forms, from eczema, migraines, food reactions, but nothing prepared me for the “crash.” That’s what I call the four months when my body suddenly refused almost everything I ate or drank. By the end, I was down to three safe foods and couldn’t even tolerate plain water.
It was terrifying, exhausting, and disorienting. But it also became the turning point that led to my diagnosis with Mast Cell Activation Syndrome (MCAS) — a condition that explained not only the crash, but the symptoms I’d carried all my life.
The First Day of the Rest of My Life
That Friday night, happy to be home from a business trip, I baked salmon with lime juice for dinner. It was a simple, healthy meal I’d made many times before.
But within hours, something felt wrong. My tongue grew numb, and then my skin grew itchy. Steve handed me a Benadryl, but the itching spread and my tongue felt like it was swelling. Another Benadryl didn’t help. By 11:30 p.m., Steve and I bundled our two young daughters into the car and headed to the ER.
The doctor on call gave me both a steroid and an EpiPen. He diagnosed me with angioedema and explained that many people come in with symptoms of anaphylaxis but never find out what triggered it. I went home shaken, but assumed it was an isolated incident.
The Banana in Traffic
Two days later, I tried to ease back into routine. Driving to work Monday morning, I peeled a banana — something I ate nearly every day.
Within minutes, while stuck in rush-hour traffic, I felt my throat tightening again. Another reaction. I turned the car around and drove straight to my GP’s office, where Steve met me. She examined me, listened carefully, and sent me back to the ER.
This time, the tests ruled out appendicitis and other emergencies. I was sent home with steroids but no answers.
Living on Three Foods
From that point on, almost everything I tried to eat or drink triggered symptoms: tongue swelling, throat tightness, itching, nausea. Even water made my throat close. The only fluid I could tolerate was electrolyte solution.
Eventually I narrowed my diet to just three “safe foods”: mashed cauliflower with mushrooms, vanilla coconut ice cream, and electrolytes. For four months, that was all I ate.
My energy plummeted. I lost a significant amount of weight. Most days I sat in a recliner in the living room so Steve could keep an eye on me while he managed the house and kids. My girls knew I was sick, but they were too young to understand the severity.
It wasn’t just the physical toll. It was the emotional devastation of food, the very thing meant to nourish, becoming poison. And to make it worse, specialist after specialist told me I was perfectly healthy.
Specialists Who Said “You’re Fine”
My GP was extraordinary. After each episode, she reassured me: “I don’t know what’s happening, but I’ll keep putting you in front of specialists until one of them has a theory.”
True to her word, she referred me to an allergist, a gastroenterologist, and a pulmonologist.
- The allergist tested me for IgE allergies. Results? Normal.
- The gastroenterologist suspected eosinophilic gastroenteritis. After an endoscopy, he told me everything looked fine.
- The pulmonologist ran a breath test. He even complimented my results: “Better than average for your age.”
Three specialists. Three dismissals. Three variations of: You’re fine.
But I wasn’t fine. I was wasting away, surviving on cauliflower and coconut ice cream, terrified every time I tried to sip water.
The disconnect between my lived reality and the test results was maddening. Unfortunately, a story many people with MCAS know too well .
The GP Who Never Gave Up
Many doctors would have stopped there. But mine didn’t.
She had already sent me through secondary care; the world of specialists like allergists, gastroenterologists, and pulmonologists. That’s what happens after primary care, your family doctor or GP, the first line of defense, the person who listens to your symptoms and decides whether you need more testing or referrals.
Secondary care is where most people find their answers. An allergist diagnoses a peanut allergy, a gastroenterologist confirms celiac disease, a pulmonologist identifies asthma. But in my case, none of those answers fit. Each specialist ran their tests and told me I was fine…even though I clearly wasn’t.
That’s when my GP made the unusual but critical decision to escalate me to tertiary care. Tertiary care means highly specialized medicine at major hospitals or academic centers: often for rare, complex, or difficult-to-diagnose conditions. It’s where you see subspecialists who spend their careers focused on small, specific corners of medicine.
In other words, it’s where you go when the “usual” answers don’t explain what’s happening.
That persistence changed my life. Without her, I may have remained stuck in limbo, like so many other patients, dismissed as anxious or overreacting, another woman told “it’s all in your head.”
Instead, my time from crash to diagnosis was only four months, when the average is several years.
Hearing the Words: Mast Cell Activation Syndrome
Finally, four months after the crash began, I sat across from a new immunologist. She listened to my story, reviewed the records, and said the words that shifted everything:
“I think you have a rare condition called Mast Cell Activation Syndrome.”
I was surprised, curious, and most of all relieved.
For the first time, someone believed me. For the first time, my experience had a name. MCAS occurs when mast cells, the immune cells designed to protect us, release inflammatory mediators too easily or too often. This can trigger a cascade of symptoms, from hives and anaphylaxis to GI distress, migraines, brain fog, and more .
Treatment and Turning Point
My immunologist immediately started me on treatment with H1 and H2 blockers to calm my overactive mast cells.
The result was dramatic. I went home and slept for 36 straight hours in the deepest rest my body had allowed in months. When I woke, I felt calm. For the first time in ages, I wasn’t braced for the next reaction.
Within a week, I began reintroducing foods. Each new addition felt like a victory. I was thrilled; Steve was cautious, reminding me to add slowly so we could track triggers. But after months of near-starvation, I couldn’t wait.
Food tasted like life again.
The Weight of Family Support
Through it all, Steve carried a heavy load: managing meals, childcare, and the household while watching me waste away. He kept us afloat when I couldn’t.
Our girls were still little then, and most of what was happening slipped past them. All they really understood was that Mom wasn’t feeling well.
I’m grateful they were spared the full weight of worry.
But I’ll never forget Steve’s quiet endurance — taking care of us every single day, even when he was scared too.
Was It Inevitable?
I’ve often wondered: was this crash bound to happen?
From what I’ve learned, many people inherit a predisposition to inflammatory sensitivity . Symptoms may stay mild or they may escalate depending on the level of triggers in a person’s life.
In my case, I had just returned from a cross-country business trip. My immunologist and I hypothesize that I picked up a virus at the conference. Already overstressed, my immune system went haywire, tipping into full-blown MCAS. The pattern is eerily similar to long COVID, which appeared a couple of years later — another condition where viral triggers push the immune system into chaos .
What I’d Tell My Past Self
If I could go back to the night before that salmon dinner, I’d tell myself one simple thing:
Take some H1 and H2 blockers (yes, the over-the-counter kind).
It wouldn’t have prevented the crash entirely, but it might have softened the blow. And it might have given me a head start in connecting the dots sooner.
Final Thoughts: Living With Answers
Those four months were some of the hardest of my life: terrified of food, dismissed by specialists, surviving on cauliflower and coconut ice cream. But they were also a crucible that forged clarity for how to adjust my life to be kinder to my body.
When my immunologist said “Mast Cell Activation Syndrome,” it reframed not only my crash but my entire life of unexplained symptoms. Suddenly, everything connected.
Today, I live differently. I plan carefully. I protect my body from unnecessary inflammation. But I also live with gratitude for my GP who never gave up, for Steve who carried us, and for finally having a name for what I’d endured.
If you’ve ever been told “you’re fine” when you know you’re not, I hope my story offers encouragement. Answers are possible. Relief is possible. And you are not alone.
