Based on the premise that the Stellate Ganglion Block For Ptsd may regulate the body's "fight or flight" response and the overactive sympathetic nervous system, which is frequently linked to PTSD, a stellate ganglion block is one method of treating post-traumatic stress disorder (PTSD). It is thought that by using an anesthetic to inhibit the stellate ganglion, the treatment may help reset or modify the body's stress response.
