Reviving Sense of Smell in Long Covid Patients: Promising Treatment Shows Results
A procedure called stellate ganglion block, which involves injecting an anesthetic into the nerves in the neck, has shown promise in reducing parosmia (distorted sense of smell) in some long Covid patients who did not respond to other therapies. Out of 37 patients who received the treatment, 22 reported improved smell distortion after one week, and 18 of them experienced significant improvement after one month. The procedure, which has been used for chronic pain, is relatively harmless and only causes temporary side effects such as a droopy eyelid and dilated pupil. Further research is needed to understand why the treatment works and its long-term effects.
