Hi, I wanted to comment on your post. First of all, I’m so sorry you’re suffering for such a long time. I too lost my taste and smell from Covid in December of 2022. It’s now March 19th 2025 and I still don’t have it back. I’ve had 7 Stellate Ganglion Block Injections and the 7th injection was successful in getting rid of my anxiety or PTSD, but I still can’t taste a single thing. Some days I can detect a more salty, sweet or bitter taste on my tongue, but no flavors of any kind. You definitely want an experienced doctor doing it. I was having a light twilight before the procedure because my blood pressure would spike so high before it. I also took a Valium. (5 mg) beforehand. My suggestion to you would be to find a doctor who has done many of these blocks and see that person. I live in the Chicagoland area and went to Northwestern in downtown Chicago to their Pain Management Clinic. They are skilled in doing this injection. I wish you luck and good health!
