I had my third covid infection in mid-December of 2022, absolutely the worst of the lot despite being fully vax'd. I was in bed for two weeks and then, like some kind of Miracle, I felt perfectly well! I was painfree for the first time in over a year and the depression was gone. My Primary said she'd "never heard of any such thing!" but other medical people said it wasn't uncommon, that sometimes it lasted & sometimes the symptoms returned.
The return of any symptoms was very gradual but this time they were different. I hit rock bottom with the depression (my Primary had referred me to a post-covid recovery clinic that was worse than useless and there wasn't a single psychiatrist with any openings so I had to rely on xanax & buspar), and then I had several severe Afib attacks. I was wearing a Holter monitor at the time and my new cardiologist was immediately notified; switched me from a beta-blocker to a calcium channel blocker & added a blood thinner. I don't know what one thing has to do with another, but I immediately felt much better.
What remains is a pitched battle with mcas (terrible leg muscle/joint pain and the itchy rash all over my torso) that my cardiologist believes was triggered by the latest Pfizer booster shot. However, I am no longer depressed; the brain fog is minimal; and the H1, H2 protocol is starting to bring relief from the itching and muscle pain.
