A nerve-block injection may help people with long COVID restore their sense of smell, new research suggests.
The injection, called a stellate ganglion block, is given into a bundle of nerves in the neck. The new study, presented Nov. 20 at the annual meeting of the Radiological Society of North America, along with other preliminary reports, hints that the injection could help long COVID patients with parosmia, or an altered sense of smell. This condition can make pleasant scents seem revolting and can have a major impact on a person's quality of life.
