I am very sorry that you’re suffering so much and are so young! I, too, suffer from Long Covid. I had Covid in December of 2022 and lost my taste and smell on day 2 of the virus and it’s now May 20o25 and it’s still not back. I have had 7 Stellate Ganglion Block injections and the 7th one took away my PTSD/Anxiety to almost 0. I do still, when I push myself to stay up late, have body tremors and sleepless nights, but I’ve learned I can no longer do that, so I don’t stay up late. I also have Hashimoto’s and stopped eating gluten, dairy and soy products and that has helped tremendously with body inflammation. I would definitely look into the Stellate Ganglion Block Injections. I had mine done at our big hospital Northwestern in their Pain Management Clinic. Good luck!
