What is Long COVID?
Long COVID, also known as post-acute sequelae of SARS-CoV-2 infection (PASC), refers to the persistence of symptoms weeks or months after the acute phase of a COVID-19 infection. This page links to individual treatment options designed to guide patients on their recovery journey. These lingering effects can impact multiple organ systems, significantly affecting quality of life. Common symptoms include:
- Fatigue and exercise intolerance.
- Brain fog and memory issues.
- Shortness of breath and chest pain.
- Joint pain and muscle weakness.
- Sleep disturbances and mood disorders.

One of the most difficult aspects of Long COVID is its variability.
Symptoms can range from mild to debilitating and often overlap with other post-viral syndromes. This complexity makes accurate diagnosis and effective treatment essential.
Dr. Groysman’s Approach to Long COVID
Dr. Robert Groysman and his dedicated staff bring a personal connection to their Long COVID care. Having dealt with the condition on a personal level, they understand the profound challenges it presents. This empathy, combined with their expertise, drives their commitment to providing effective, compassionate treatment.
Dr. Robert Groysman specializes in providing comprehensive care for patients suffering from Long COVID. His approach focuses on identifying and addressing the root causes of symptoms through personalized treatment plans that may include:
- Advanced Diagnostics: In-depth testing to uncover the underlying drivers of symptoms, including inflammation, immune dysfunction, and autonomic dysregulation.
- Targeted Therapies: Evidence-based treatments like vagus nerve stimulation, mitochondrial support protocols, and stellate ganglion blocks.
- Lifestyle and Nutritional Interventions: Tailored dietary recommendations, stress management techniques, and exercise plans to promote recovery.
Why Choose Comprehensive Care?
Published research supports several of these approaches. A 2023 retrospective cohort study (Pearson L, et al., Cureus) reported symptom relief in 86% of 41 Long COVID patients treated with stellate ganglion block. Results in any individual case vary, and SGB remains an off-label use.
Long COVID requires a multidisciplinary approach that addresses both physical and emotional health. Dr. Groysman’s expertise in pain management, immunology, and holistic care ensures that patients receive support for every aspect of their recovery journey.
Patient Success Stories
Dr. Groysman & his team are so wonderful. I came in for 2 SGB’s and an EAT procedure. I flew in and felt so comfortable with the staff. I got some relief from my long covid and dysautonomia as well! I came back the next day for an ANS test and you couldn’t ask for a more knowledgeable doctor and staff who have experience! – Amy M.
When I first engaged with Dr. Groysman I was at the point of desperation due to intense long Covid symptoms. Before seeing him I had seen numerous doctors who were unable to provide much help. Some of their recommendations actually made me more sick. Dr. Groysman developed a treatment protocol specific to my situation and my needs. I’m not being dramatic when I say with these treatments I have been resurrected.
I’m no longer struggling with debilitating cognitive, emotional and physical fatigue. My crushing headaches, head pressure and tinnitus are gone. The horrible cough that kept me from sleeping for more than a year and a half is gone. My body feels like I’m alive again.
I still have to pace myself as my body continues to heal. But it’s simply life changing to be able to hold a conversation without feeling as if I’m going to collapse, to enjoy cooking again, walk my puppy, grocery shop, or go to the nursery.
Thank you Dr. G and your amazing staff. You saved my life! – Lisa W.
Amazing team. I travelled to this clinic from Ireland and from the start the communication was brilliant. On arrival every member of staff were so polite, attentive and kind. Chris, Hailey, Caroline, Dawn and Dr Groysman everyone was just fantastic. Keep up the good work 💪 – Rose F.
My daughter suffered symptoms of long-covid for 3 years, significant enough that she was unable to attend her sophomore year of high school in-person. We searched all this time for anything that would restore her health. We finally found that help with Dr. G, and thanks to his care she reports an 80% improvement. She finally has her life back! We are so grateful and excited to watch her continue to improve with his help. – Janet L.
Dr. Groysman is the only doctor in the US currently offering Epipharyngeal Abrasive Therapy (EAT) EAT in combination with Stellate Ganglion Block (SGB) for long-haul covid. After my first treatment, I already feel more energy and a sense of clear-headedness that I haven’t felt in months. I highly recommend him to anyone who wants innovative and specialized care for post-covid syndrome. – Nat C.
