While many remain unfamiliar with it, Stellate Ganglion Blocks (SGB) can be a life-changing advance in modern medicine to help calm anxiety and fear-based responses. SGB is a safe, ultrasound-guided injection that targets a collection of nerves in the neck, blocking impulses that trigger fear- and anxiety-based responses in our bodies, such as with post-traumatic stress disorder (PTSD). SGB is an outpatient procedure, taking less than thirty minutes to administer. The effects, which are often felt immediately, can last for up to several years.
