According to a recent clinical study by Research Triangle Park-based RTI International, a procedure historically used to treat pain could also be used to help people with post-traumatic stress disorder. Researchers found that a treatment called stellate ganglion block (SGB) improved symptoms of PTSD in their study participants. SGB is a 30-minute procedure used to treat nerve injuries or pain in the upper body and has little to no recovery time. Researchers are waiting on more grants to further study the effects of SGB treatment for PTSD patients
