My first was rough, today feels about the same as yesterday but no worse, a bit sniffy, not very wet nose, some leg ache which was peculiar for me the first time. I guess my pancreas is getting hit again. Lungs feel fine though, no cough.
I'm still prone to believe that there is a degree of the inoculation dose level effect.
The first time I was driving my father-in-law somewhere for two hours and he was solidly ill with it. But it was a very hot place so I put on the AC to help him risking his "Christmas (2019) cold". I was solidly exposed, symptoms in four days. This time it was just a brush, probably just from the Uber door handle or whatever.
But I have no science, just that's my impression from over the years in medical environments. Inoculation level seems important.
Did you get a second PCR test to be sure? I remember when Elon Musk tweeted (2 years ago?) that he got 4 tests in a row, two were positive and two were negative. I can't imagine him having any reason to lie about that, and I myself have always been suspicious of the accuracy of those tests.
I remember early last year when myself and a few friends all got woefully symptomatic with what we thought was Covid, but all our PCR tests came back negative, so we chalked it up to RSV which was showing it's face 'round these parts at the time.
