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.
