Summary
This study tested whether a stellate ganglion block—a shot that numbs certain nerves in the neck—could help people who lost their sense of smell after COVID-19. Twenty adults with smell problems lasting at least a year took part. Researchers measured changes in smell ability and overall improvement to see if the treatment is safe and effective.
