When the nervous system is stuck in overdrive after COVID, calming it down can change how you feel day to day. Two nerves sit at the center of that calming: the vagus nerve and the trigeminal nerve. Stimulating them gently is one of the more promising, lower-risk tools for dysautonomia, fatigue, and brain fog.
This is the first layperson’s guide to both vagus and trigeminal nerve stimulation for Long COVID. It explains what these nerves do and how to work with them, in plain language, so you can try something active rather than only avoid triggers.
What you’ll find
Most Long COVID advice is about what to avoid. This is about something you can actively do to help your nervous system recover.

Robert Groysman, MD
He began treating Long COVID before it had a name, after a stellate ganglion block unexpectedly restored the taste and smell in his post-COVID patients. That was the first clue that something deeper was going on.
He has experienced Long COVID himself. This series is based on findings in his own practice.
Written for a patient, not a textbook
“A thorough explanation of the role the vagus and trigeminal nerves play in dysautonomia.”
“It explains the vagus and trigeminal nerves in a way that’s actually easy to get. A great, no-nonsense guide.”
