Much appreciated. I know there are many who believe Covid is just the flu, but it isn't. It is unlike any virus I've had. My symptoms were always bizarre and not flu like at all. The first time I got it, the only symptom I had was I couldn't taste or smell anything. It was about a month later when my nerves went berserk and I got a blood test to confirm that I had high antibody count.

I hope this helps your friend and I highly recommended finding a good functional doc who will listen.
