Patient Advocate & Speaker

Kevin Crosson speaks truth to medicine.

A competitive golfer and LMU student who ran miles daily. Then, at 19, his heart gave out on the 405 freeway. Two months later, he was unresponsive on the floor of his home while his father performed CPR for 8 minutes. What followed was years of dismissal by 70 doctors — and a system that kept making him wait while his body kept getting worse.

01 — His Story
01

A documented case of vaccine-induced cardiac and immune injury — dismissed, survived, and now undeniable.

From a cardiac event
on the freeway to a platform
they can't ignore.

Before March 2022, Kevin Crosson was a competitive golfer, an LMU student, and an athlete who ran five to seven miles and spent hours in the gym. He had his whole life ahead of him. Then, at 19, his heart gave out while driving on the 90 freeway in Los Angeles. Heart rate over 180, he somehow made it to his apartment. His roommate found him on the floor and drove him to the ER.

Two months later, Kevin collapsed at home — fully unresponsive. His father performed CPR for 8 minutes. Not a single physician followed his case after that. He was told to relax. He was offered antidepressants. He was dismissed by doctor after doctor at the country's best institutions.

The pain during this period was unlike anything he could have imagined. A burning, pins-and-needles sensation across his chest so intense that he would tear at his own skin trying to get relief. More than 10 hospitalizations. Countless cardiac events. And no answers — until he became medically fluent enough to find them himself.

At 21, diagnoses were finally confirmed: coronary vasospasm, microvascular dysfunction, POTS, and mast cell activation syndrome. But getting diagnosed was only the first fight. The treatments his specialists prescribed were denied by insurance — and denied again on appeal. His POTS developed during one of those standstills. Every delay brought a new condition, more damage, less reversibility.

He is 23. He takes 25 pills a day. He sleeps upright. After a year of magnesium infusions five times a week, he has exhausted that path. He will never play competitive golf again. And he is still fighting.

What they actually said

Words spoken to a patient
already in crisis.

You're being dramatic. It's not your heart. Just relax.

Internist

Said after Kevin's first cardiac event — while driving on the freeway at age 19. His father had just performed CPR.

I bet one day you'll wake up and feel normal again.

Mayo Clinic Physician

Said to a patient with documented coronary vasospasm, POTS, and mast cell activation syndrome who had already been hospitalized over 10 times.

He was in a documented medical crisis. The evidence was always there. They chose not to look.

Diagnosed at 21 — Still Fighting for Treatment

The second fight

Getting a diagnosis
was only half the battle.

After years of being dismissed by doctors, Kevin finally had answers at 21 — confirmed by cardiac catheterization and a team of nationally recognized specialists. Then insurance stepped in.

The treatments his doctors prescribed as medically necessary were denied. He went through the formal appeals process. Denied again. During one of those standstills, he developed POTS — an entirely new incurable condition his care team believes could have been avoided with timely treatment.

He wrote a formal appeal to the Department of Managed Health Care. He cited research studies. He described the burning, the pain, the sleepless nights. He wrote: "I sincerely hope that I get the opportunity to trial IVIG, as the thought of this providing just a moment pain-free is my only hope left."

His story is not unique. It is the system working exactly as designed — for everyone except the patient.

Medical Gaslighting & Dismissal

How elite institutions fail complex patients — and the real cost when that failure compounds over years. A firsthand account backed by documentation.

A documented case of vaccine-induced vascular and immune injury, now recognized in FDA-updated warnings. Kevin speaks carefully, specifically, and with records to back every claim.

Insurance Denials & Patient Rights

The second battle no one talks about: getting treatment approved after diagnosis. Kevin has lived the appeals process and emerged with a clear message for patients and policymakers.

04 —

POTS, MCAS & Dysautonomia Awareness

Conditions that are real, measurable, and systematically misattributed to anxiety — and what it takes to get them recognized by a system that resists the diagnosis.

05 —

Navigating Rare & Complex Disease

Practical and emotional frameworks for patients who've been failed by standard diagnostics. What to document, how to persist, and when to trust yourself over the system.

The Cost of Delay: A Systemic Critique

Every denial, every dismissal, every "come back in six months" has a medical consequence. Kevin puts a human face on what deterioration by bureaucracy actually looks like.

Proven audience.
Real story.
Ready now.

Kevin combines something rare: the documentation to back every claim, the medical fluency to explain it clearly, and an audience that proves the story already resonates. His TikTok following wasn't built on performance — it was built on truth.
