Stellate Ganglion Block (SGB)
SGB has been useful in treating many disorders, such as PTSD. Groysman discovered that it is also effective against long COVID-19 when he was treating a military veteran for PTSD. “He also had long COVID, and we saw an immediate resolution of his olfactory symptoms with SBG.” In this outpatient procedure, the physician uses ultrasound as a guide to block the nerves used by the sympathetic nervous system to communicate between the head and the rest of the body. The process takes 10 to 15 minutes and is done without sedation. Improvement in taste and smell are usually felt within 5 minutes, says Groysman.
TENS Vagus Nerve Stimulation
The vagus nerve, which is essential to several body functions such as breathing, heartbeat and digestion, may thicken with long COVID. TENS is a small unit that delivers electrical impulses to nerves and is normally used to treat the pain associated with sore muscles. Groysman has repurposed TENS to deliver impulses for vagus nerve stimulation at the ear. He says it may take a month or longer to get results, but patients need to follow a specific protocol. The beauty of TENS is that it is inexpensive and can be done at home.
