@po777 I wasn’t sure who you were asking about what were they doing to treat taste/smell, but I will answer what I’ve done. I had 7 Stellate Ganglion Block Injections that finally took my PTSD/Anxiety way down. I also was having Green Violet Laser Light Therapy and also Red Light Therapy on my tongue, vagus nerves, sinuses. I did this light treatment through my Chiropractor and just stopped doing them, as I had about 3 months of treatments and stopped noticing any progress. I am currently seeking treatment at a Holistic Wellness Center having facial, mouth and head lymphatic massages. Time will tell if this is helping. I’m finding that I’m blowing my nose more frequently and hoping this is getting rid of some of the inflammation causing this.🤷‍♀️
