The Complete Long COVID Handbook

The Complete Long COVID Handbook, Volume 2: Dysautonomia

By Dr. Robert Groysman, MD

A roadmap to one of Long COVID's most overlooked root causes.

Millions are living with lingering symptoms after COVID-debilitating fatigue, brain fog, dizziness, palpitations, gut issues, sleep problems, and strange neurological sensations. At the center of these struggles lies dysautonomia, a malfunction of the autonomic nervous system that controls heart rate, digestion, temperature, and more.

In this groundbreaking volume, Dr. Robert Groysman-board-certified anesthesiologist, pain medicine specialist, and pioneer in Long COVID care-explains how dysautonomia fuels persistent symptoms and, most importantly, how to treat it.

Inside, you'll discover:

• Clear explanations of how the autonomic nervous system works-and what happens when it's stuck in "fight or flight."
• Practical tools to recognize, test for, and monitor dysautonomia, including HRV and COMPASS-31.
• Therapies that restore balance:
  • Stellate Ganglion Block (SGB)
  • Vagus Nerve Stimulation (tVNS)
  • Epipharyngeal Abrasive Therapy (EAT)
  • Medications, supplements, and breathing protocols
• How stress, inflammation, and poor sleep worsen symptoms-and strategies to reset the system.
• Real patient stories that highlight recovery, setbacks, and hope.

More than symptom management

Dr. Groysman connects dysautonomia to conditions such as POTS, MCAS, ME/CFS, and neuropathies, showing how these fit into the larger Long COVID puzzle. He translates complex science into clear, actionable steps patients can take to their doctors-without overwhelming jargon.

• Patients searching for answers and a plan to move forward.
• Caregivers who want to understand what their loved ones are going through.
