@robinrm There is really nothing to be nervous about. The Stellate Ganglion Block injection are of Lidocaine, which is a pain blocking medication, that is injected into your parasympathetic veins in your neck, guided by ultrasound so they see exactly where the injection is going. You will have a Horner’s Syndrome happen to the opposite side where your eye will droop for a while, but will return to normal by end of day or next day for sure. It’s not painful, but I ask for a twilight sleep because I get nervous before the procedure as well and my blood pressure shoots up! I live in the suburbs of Chicago, so I went to the Pain Management Clinic at Northwestern Hospital in Chicago on Erie. It’s worth a try and what they did for me was take my PTSD/Anxiety down and that is a blessing. Still waiting on getting my taste and smell back, but many of my side effects from Covid are dissipating, so I’m hopeful that too will come back.🤞
