This is terrifying. I am 8 weeks in after testing positive. A blood exam reveal no more viral or bacterial infection but I still experience some anxiety and brain fog, today was one of those days (yesterday was an awesome day on the other hand).
I get cold hands all the time when I am starting to feel unwell.
