When Every Test Says You're Fine (But You're Not)... It's Time for a New Conversation
Discover why mechanism-based Long COVID diagnosis is different from traditional approaches.
Dr. Groysman patiently listened and made great suggestions during a telemed visit. Looking forward to working with him and his clinic in the future. – L.C.
A Framework Born from Personal Experience
I’m Robert Groysman, MD, and I developed the approach you’re about to discover after recovering from my own battle with Long COVID.
After treating hundreds of Long COVID patients I’ve identified six distinct mechanisms…
I could tell you that he is smart, thinks outside the box to help patients, and is well researched on the latest techniques (all of which are true), but I think that the most important thing is that he is kind. – L. C.
The Six Mechanisms We Verify
Dysautonomia – Autonomic nervous system stuck in crisis mode are unable to regulate heart rate, blood pressure, digestion, temperature
Mitochondrial Dysfunction – Cellular energy production impaired can trigger profound fatigue even when nutrient levels are normal
Endothelial Damage & Microclots – Microscopic clots can restrict oxygen delivery; standard clotting tests miss these entirely
Gut Dysbiosis – Microbiome imbalance can disrupt the gut-brain axis, serotonin production, and immune function giving birth to symptoms that seem unrelated.
Hormone Imbalance – Persistent inflammation affecting nervous tissue, driving brain fog and cognitive symptoms
Mast Cell Activation – Immune cells releasing inflammatory chemicals inappropriately, causing allergic-type reactions without actual allergens
These mechanisms interact with gut dysbiosis affecting autonomic function, impairing mitochondrial efficiency, contributing to inflammation.
This is why you have cardiac AND neurological AND GI symptoms simultaneously.
Why Your Test Results Are Coming Back Normal
Long COVID isn’t mysterious.
It disrupts multiple parts of the body at the same time through six distinct mechanisms. Standard medicine tests for structural damage and acute disease.
But they don’t evaluate functional dysregulation.
Think of it this way, your organs may be structurally intact while the systems controlling those organs have lost their calibration, like driving a car with the emergency brake on.
We consulted with Dr. Groysman in April of 2023, and after over a year of research and watching his continued success, we decided we needed to consult with him again for my daughter this summer. We had the consult in May and based on her symptoms, she was a candidate for the stellate ganglion block and EAT. – B.P. 7/2024
From Dismissed to Diagnosed
I was worried that the SGB wouldn’t work because I’ve felt bad for so long.
Woke up the next day feeling great because I slept so well! No fatigue! I had the EAT done that morning because Dr. Groysman said it works synergistically with the SGB.
After decades of being gaslighted and ignored, it was so reassuring and validating to find a doctor who cares and listens AND helps. Best money ever spent!! Thank you, Dr. Groysman!

"After more than 4 years with LONG COVID, the world is more clear, more colorful, more crisp. I no longer have the bone crushing, soul defeating fatigue, among the other list of symptoms.
I can tell my body and my nervous system are still figuring out how to work together again, but my heart rate through energy consumption is easily 10 points less than it was before Monday.
Dr. Groysman is exactly the right person in the right place at the right time. It's been 5 days since my first EAT. My recovery has been nothing short of miraculous. You have saved my life in so many ways and will forever be in my prayers of Thanksgiving."

Ready to Be Heard?
If you’ve been told your symptoms aren’t real because your tests are normal, if you’ve seen multiple specialists who found nothing wrong, if you experience multi-system symptoms not fitting into conventional diagnoses, mechanism-based evaluation may provide the insights you’ve been looking for.
We want to hear from you if…
- Your standard tests are repeatedly normal despite persistent symptoms
- You’ve been dismissed by multiple specialists
- You have cardiac, neurological, GI, and immune symptoms simultaneously
- You’re seeking root-cause diagnosis, not just symptom management
Note: Companies limit coverage so we’re unable to accept insurance for these procedures.
