@kris1130 I share your frustration and offer something for you to consider. I chased the Long COVID/Vaccine Injury rabbit for about 3 years (beginning November 2021, first and last vaccine booster) until I found a Doctor on my own (all the local Doctors including Mayo Clinic Rochester testing came back normal). After treatment by Dr. Bruce Patterson (I had considered Dr. Vaughn), and no improvement after test 2, Dr. Patterson said hmmmm, we should test you for Lyme and Mold Illness. I tested positive for Mold (Mycotoxins). Turns out there are many crossover symptoms which confuses medical professionals (if they even think of testing for Mold Illness). At about 5 months (and 4-1/2 years after symptom onset) on the Mold Illness regimen, my health is returning, I can exercise, my brain fog is gone, and I feel like doing things again (in reflection the most damning symptom is 'amotivation' - not wanting to do a damn thing about anything. Mold Illness even exists in dry climates like Arizona and its usually caused my mold exposure in your home (its that old house smell). Take a moment and watch a YouTube video by Dr. Andrew Campbell and see what you think. Best wishes on your journey.
