What Is Long Covid?

Long covid, long hauler’s or post acute sequalae syndrome (PASC) as its been called over the last few years is a multisystem condition that can occur weeks after recovering from a covid-19 infection.  Even if the infection was mild or asymptomatic, you can still develop long covid.  It often causes chronic fatigue, brain fog, post exertional malaise, taste and smell abnormalities, neuropathies, abdominal pain and bloating, chest pain, and vibration sensations.  These are but some of the 203 recorded symptoms.  Long covid is also associated with postural orthostatic tachycardia syndrome (PoTS), chronic fatigue (ME/CFS), and mast cell activation syndrome (MCAS), each with there own set of symptoms.  Some people continue to suffer from these issues for over 3 years.  Dr. Groysman treats long covid daily.  He is the leading expert.

Because of the breadth of symptoms and multisystem involvement, it requires extensive experience and knowledge of the mechanisms involved in order to understand how to treat it.  This is the where the expertise of Dr. Groysman comes in.  While he started treating long covid with a stellate ganglion block (SGB), he has expanded treatments to external vagus nerve stimulation, nicotine patch, prescription medications, supplements, herbals, and IV therapy.
