Effect of Stellate Ganglion Block on ME/CFS

Completed · Phase 1

Conditions studied: Encephalomyelitis, Myalgic, Chronic Fatigue Syndrome, Chronic Fatigue Disorder, Chronic Fatigue and Immune Dysfunction Syndrome, Myalgic Encephalomyelitis, Postviral Fatigue Syndrome, Systemic Exertion Intolerance Disease, Infectious Mononucleosis-Like Syndrome, Chronic, Chronic Fatigue-Fibromyalgia Syndrome

In brief

The goal of this clinical trial is to study the effects of stellate ganglion block (SGB) in participants with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). The main questions it aims to answer are: Does SGB treatment improve symptoms of ME/CFS (e.g. brain fog, fatigue)? Do changes in symptoms go along with changes in blood or saliva? Participants will receive a total of six blocks over three weeks (one block on each side, one day apart, per week). Prior to treatment and at two points following treatment, participants will complete surveys, take a cognitive (puzzle type) test, and provide blood and saliva for analysis. Participants will measure their heart rate daily using a free smart phone app.
