Revolutionary Treatment Restores Sense of Smell in Long COVID Patients

A new study suggests that a novel treatment called stellate ganglion block could restore a normal sense of smell and taste in people with long COVID who have not responded to other therapies. The treatment involves injecting anesthetic into a cluster of nerves in the neck to stimulate the autonomic nervous system. In a study of 54 participants, 22 reported improved symptoms a week after treatment, with additional significant improvement a month later. Three months later, there was an average 49% improvement in symptoms among the group. However, not all patients responded to the treatment, and further research is needed.
