Long-Haul COVID-19, also known as Post-Acute Sequelae of SARS-CoV-2 (PASC), can cause lingering symptoms that affect daily life. At Text2MD, Dr. Miguel Antonatos, a board-certified internal medicine physician, specializes in treating Long-Haul COVID patients through personalized telemedicine care. Our goal is to help you manage persistent symptoms and improve your quality of life.
Long COVID, or post-acute sequelae of SARS-CoV-2 infection (PASC), can present a range of symptoms that persist or emerge after the acute phase of the infection. Common long haul symptoms include:
These symptoms can last for weeks or even months after recovering from the initial COVID-19 infection. The severity and duration vary from person to person.
Personalized. Integrative. Data-Driven.
The AVIDAMD Method, developed by Dr. Miguel Antonatos, blends leading protocols, precision medicine, functional medicine, advanced lab interpretation, and AI-guided precision care to help patients recover from Long COVID and post-viral syndromes.
Combines leading protocols (I-Recover, NIH, CCTC, Precision and Functional Medicine Methods)
Tailored plans based on symptoms, labs, and phenotype
Supports immune balance, gut health, mitochondrial repair & nervous system reset
Continuous personalization, driven by intelligent AI algorithms
Microvascular inflammation & clotting
Immune dysregulation & cytokine imbalance
Mitochondrial dysfunction
Mast cell activation & autonomic imbalance
Founder of the AVIDAMD Method for Long COVID Recovery
I’m a board-certified internal medicine physician with over 15 years of experience treating chronic inflammatory and metabolic conditions in both hospital and outpatient settings. Since the onset of the COVID-19 pandemic in 2020, I’ve been at the forefront of caring for patients affected by Long COVID—providing telemedicine-based care across the U.S., Europe, and Latin America.
As the pandemic evolved, I developed and implemented a specialized clinical methodology—the AVIDAMD Method—to address the complex, multi-system effects of post-viral syndromes. This approach integrates cutting-edge research in immunology, virology, mitochondrial health, and functional medicine with real-world, evidence-based clinical care.
My work has focused on understanding how SARS-CoV-2 contributes to persistent symptoms through key mechanisms such as:
Endothelial inflammation and microvascular dysfunction
Hypercoagulability and microclot formation
Immune dysregulation and mast cell activation
Persistent viral reservoirs and chronic immune activation
Mitochondrial dysfunction and microbiome imbalance
These insights form the foundation of the AVIDAMD Method—a precision-guided, integrative care model for Long COVID recovery. This methodology emphasizes:
Phenotype-specific treatment planning
Strategic use of repurposed medications and targeted supplements
Mitochondrial, hormonal, and metabolic support
Immune system modulation and anti-inflammatory protocols
Restoration of autonomic nervous system balance and gut-brain health
Unlike traditional, symptom-based protocols, the AVIDAMD Method uses a whole-person, root-cause-driven approach. While pharmacologic tools are utilized when appropriate, my primary focus is on restoring long-term function and well-being through personalized, compassionate, and holistic care.
I’ve seen firsthand how this method can lead to meaningful, lasting improvements—helping patients not just manage symptoms, but reclaim their lives.
Long COVID (also called post-acute sequelae of COVID-19 or PASC) refers to persistent symptoms that last weeks or months after the initial COVID-19 infection has cleared. These may include fatigue, brain fog, shortness of breath, chest pain, and more.
If you’ve had COVID-19 or COVID Vaccine in the past and are still experiencing lingering symptoms—especially fatigue, brain fog, or rapid heart rate—you may have Long COVID or Vaccine Injury. We use symptom screening, lab testing, and clinical evaluation to assess this.
We use the AVIDAMD Method: a personalized approach involving advanced lab work, lifestyle strategies, nutritional support, repurposed medications (if needed), and close follow-up. Every treatment plan is tailored to your symptoms and phenotype.
Yes. Lab testing helps identify underlying inflammation, immune imbalance, micronutrient deficiencies, viral reactivation, and hormone imbalances. We offer guidance on affordable self-ordered labs if needed.
No. We operate on a direct-pay model to provide transparent pricing and personalized care without insurance restrictions. You may use your HSA/FSA funds.
Yes. We offer a one-time consult to review your symptoms and provide recommendations. However, ongoing support is often needed for Long COVID recovery, so many patients choose a membership plan.
Recovery timelines vary. Some patients see improvement within a few weeks, while others require several months of support. The goal is sustainable progress through a phased, root-cause approach.
