Could a simple neck injection bring back smell for long COVID sufferers?
NCT ID NCT05445921
Summary
This study tested whether a stellate ganglion block—an ultrasound-guided injection of local anesthetic into a nerve bundle in the neck—could help people who lost or had changes to their sense of smell after COVID-19. The goal was to see if this procedure could improve smell and potentially ease other long COVID symptoms like fatigue and 'brain fog' by calming an overactive nervous system. Twenty adults with persistent smell problems for over a year after COVID participated in this early-stage pilot study.
