Neck injection tested as potential fix for COVID's weird smell side effect
NCT ID NCT06253806
Summary
This study tested if a stellate ganglion block—a targeted injection of local anesthetic in the neck—could improve distorted smell (parosmia) in people with Long COVID. In this double-blind trial, 48 participants were randomly assigned to receive either the real injection or a placebo saline injection. The goal was to see if the procedure could reset nerve signals and provide relief for this persistent and distressing symptom.
