Can you recover from Long COVID with CFS, MCAS, and POTS?

Many people have. Niki was diagnosed with 14 different conditions after her initial COVID infection in March 2020, including chronic fatigue syndrome, mast cell activation syndrome (MCAS), POTS, and fibromyalgia. She was 85% bedbound and lost 33 lbs because she couldn't eat any food. Through nervous system retraining, she recovered and now dances, socializes, drives herself, and does handstands.

What are the symptoms of mast cell activation syndrome after COVID?

Niki's MCAS symptoms after COVID included allergic reactions to nearly all foods, flushing, rashes, tachycardia, throat closing, sharp electrical pains in her head, and sensations like electricity going down her back. She lost the ability to eat completely and was even having reactions to water and salt. Her mast cells were releasing histamines erratically, causing reactions to foods, stress, heat, and smoke.

How bad can Long COVID symptoms get?

Niki's Long COVID progressed to 14 diagnoses over three years. At her worst, she was 85% bedbound, lost 33 lbs from inability to eat, had a resting heart rate in the 150s for two hours while lying flat, scooted down stairs because she couldn't stand, needed someone to bathe her, lost cognitive ability and couldn't form sentences, and had her muscles atrophy from being still.

What is nervous system retraining for Long COVID?

Nervous system retraining uses neuroplasticity protocols to help the nervous system move out of a stuck stress response. Niki's nervous system was stuck in a heightened state after COVID, driving symptoms like MCAS, POTS, chronic fatigue, and fibromyalgia. Through CFS Recovery's coaching program, she retrained her nervous system using structured protocols, community support, and daily coaching. Within months she went from bedbound to living a full life again.

Is recovery from Long COVID with MCAS actually possible?

Niki's story shows that recovery is possible even with severe MCAS. She went from having allergic reactions to water and salt, losing 33 lbs, and being unable to eat any food to dancing, socializing, driving herself home for the first time in years, going on vacations, and doing handstands. She recovered through nervous system retraining after three years of illness and 14 diagnoses.

What Caused Niki's Long COVID and CFS?

Niki was the last person you'd expect to end up bedridden. Just one year before getting COVID, she was working three jobs to pay off her student loans. She'd just been offered a department head teaching position. On top of that, she was in the gym 4 to 5 days a week doing bodybuilder-style workouts, often spending 3 hours there after a full day of work.

She didn't have a single day off. Teaching during the week, department head duties, hiring, lesson plans on weekends, and intense gym sessions. Her nervous system was already under massive stress. She just didn't see it yet.

"It makes sense why I crashed as hard as I did. It's kind of comical looking back at it now, thinking that I was in the best shape of my life. Meanwhile, I was working myself to the bone and my nervous system was screaming at me to stop. I just didn't listen to the signs at all."

The COVID trigger

On March 13, 2020, Niki got sick. It was the last day of teaching before everything shut down. She felt an uncomfortable tingling in her chest that grew worse over the following days. Shortness of breath, coughing, fever, and loss of taste and smell followed. Her doctor refused to let her get tested for COVID because it was so early in the pandemic. When she finally got tested, it came back negative.

But she kept getting worse. The long COVID symptoms started trickling in: tachycardia, heat intolerance, intense brain fog, and dizziness so bad she had to guide herself through her house by holding onto walls. By July 2020, she had to stop working completely.

Research confirms this pattern: a 2022 study in Nature Medicine found that approximately 10-30% of COVID-19 survivors develop long-term symptoms affecting multiple organ systems, with nervous system dysregulation as a central mechanism. Davis et al., 2023

How Bad Did Niki's Symptoms Get?

Over three years, Niki was diagnosed with 14 different conditions from her initial COVID infection. The list included CFS, MCAS (mast cell activation syndrome), POTS, fibromyalgia, and more. She went through a laundry list of specialists: cardiologists, pulmonologists, rheumatologists. Each one either couldn't help, didn't believe her, or told her it was anxiety.

The ER visit that changed everything

In November 2020, Niki had one of her worst episodes. Her body flushed, went numb and tingly, and her heart rate spiked. She went to the hospital. They took one look at her heart rate and threw her on the table for EKGs. Her vision started going. Her hearing started going.

"My heart rate was in the one fifties for 2 hours. And this is me laying down. I'm not vertical at all. I was convinced I was having a heart attack and I would not leave that table. The thoughts that raced through your head when you're thinking you're not going to make it out of there, those feelings don't leave you."

After 2 hours at 150+ bpm and another 2 hours at 130+ bpm, her heart rate finally came down. The next morning, the doctor told her it was anxiety. She pushed for testing. They found a mitral valve prolapse but said it was common for women her age and wouldn't cause her symptoms. She left with no answers. Again.

Rock bottom: losing the ability to eat

April 2021 was when Niki hit her absolute lowest point. During a neurocognitive therapy session at home, she pushed through warning signs and her heart rate spiked to 170 bpm. She called 911. That episode flipped something in her nervous system. The MCAS, POTS, and CFS symptoms exploded.

One by one, she started losing foods. Every meal triggered allergic reactions: flushing, rashes, tachycardia, throat closing, sharp electrical pains in her head, sensations like electricity shooting down her back. She lost 33 lbs because she couldn't eat anything at all. Not a single food. She was even having reactions to water and salt.

"I lost the ability to eat completely. There was not one food. I was even having allergic reactions to water and salt. My allergist recommended a feeding tube because I couldn't eat anymore."

She eventually found three foods that her body could tolerate: potatoes, salmon, and peas. That's all she ate, every day, for months.

Mast cell activation syndrome (MCAS) involves erratic histamine release that can cause severe multi-system reactions. A 2021 review in Current Allergy and Asthma Reports documented the connection between post-viral immune dysregulation and MCAS onset. Afrin et al., 2021

What Was Daily Life Like at Niki's Worst?

At her worst, Niki was about 80 to 85% bedbound. Her bedroom was upstairs. Just standing would send her heart rate into the 150s, so she scooted down the stairs to get to the couch. That was her entire world: bed to couch and back.

She couldn't walk to the refrigerator, get her pre-prepared food, and put it in the microwave. Someone had to be there just to do that for her. Her muscles atrophied from being so still. She couldn't bathe herself anymore.

"There were times I couldn't even get in the tub. My friend had to come over and we put a beach chair outside of my driveway and she bathed me with a hose in my driveway because I couldn't get into the tub."

Losing cognitive function

On top of the physical symptoms, Niki lost a good chunk of her cognitive ability. She couldn't recall words. She couldn't have cohesive conversations. She ended up acting out what she needed, using hand gestures and signs, because the words just weren't there in her head.

Losing her dog at rock bottom

While Niki was at her absolute sickest in July 2021, her dog got sick and she had to put him down. He'd been with her through the passing of her father, through her Crohn's diagnosis, and through this entire illness. He was her rock, her constant, her lifeline.

"He kept me going and to lose him when I was lost myself, that brought me to a new level of hopelessness and brokenness. That broke me completely."

On top of everything, she'd been told in March 2021 that she had moderate to severe pre-cancerous cells that needed surgery. Doctors pushed the surgery because they were worried she'd react to anesthesia. She was left wondering if cancer would develop on top of everything else. She finally had the surgery in August 2021 and the cells were removed successfully.

What Treatments Did Niki Try Before CFS Recovery?

Niki went through the full circuit. Cardiologists (multiple), rheumatologists (multiple), pulmonologists, allergists, emergency rooms, the Mount Sinai Post-COVID Center in New York. Her mom drove her an hour and a half each way to appointments because Niki couldn't drive. Even the drive wiped her out.

She tried a neurocognitive therapy called Neuron Up through her functional medicine doctor. She tried a low histamine diet. She tried another brain retraining program before CFS Recovery. It introduced her to the concept that this was a nervous system issue, but it wasn't the right fit.

Test after test came back "normal." Doctors kept telling her she was fine, but she clearly wasn't. They even stopped running certain tests because she'd been exposed to too much radiation from all the X-rays and CT scans.

How Did Niki Find CFS Recovery?

Niki found CFS Recovery through Crista Taylor, who is now one of the program's coaches. Crista also got sick with COVID in 2020. They were part of a group of people on Instagram who got sick around the same time and leaned on each other for support, sharing what worked and what didn't.

When Crista joined CFS Recovery's program and started recovering, Niki's ears perked up. Their stories were similar. If Crista could recover, Niki believed she could too.

"I refused to accept that this was going to be my life. I refused to accept that I couldn't eat for the rest of my life. I refused that I could only shower once a week, barely. I just wouldn't accept it."

She watched the recovery stories on YouTube. She saw people with similar conditions recovering. She joined in October 2022.

How Did Niki's Recovery Progress?

When Niki started the program, she was about 80 to 85% bedbound. Most days, she could go downstairs, heat up a pre-prepared meal her mom had cooked, and go back upstairs. That was it. The rest of the day was spent in bed, feeling symptoms.

The adjustment period was different this time

In the first couple of weeks, Niki hit an adjustment period. But this time was completely different from past flare-ups. She had the coaches as her voice of reason when her amygdala wanted to talk her into irrational fears.

"You guys were that logical part of my brain that I was missing at the time. And that made all of the difference. Having that constant reminder and that community, the group and everybody cheering me on. It creates a family and this sense of belonging and understanding that you are missing completely when you're trying to do this on your own."

The combination of coaching support, community, and structured nervous system retraining protocols gave Niki the foundation she needed. Within months, everything started shifting. She went from being bedbound to living a full life. Dancing, socializing, driving herself home for the first time in years, going on vacations, and doing handstands.

A growing body of evidence supports nervous system-based approaches for post-viral conditions. A 2022 study in Frontiers in Neurology found that neuroplasticity-based interventions can help recalibrate autonomic dysfunction and reduce multi-system symptoms in post-COVID patients. Renz-Polster & Scheibenbogen, 2022
