It's a good kind of negative. A member of my household had occasion to be tested for COVID-19. I was very interested in the results, since I've been feeling like hammered shit myself for the last week or so.
Test results arrived yesterday. Whatever it is, it's apparently not COVID-19 (unless it was a false negative). And I started feeling a little better yesterday, to the point that I was able to stop considering whether to move my desk and computer into the bathroom (my symptoms were somewhat different from the other person's, but all were consistent with the possibility of the dreaded SARS-COV-2 virus being involved), and even went to the store last night, since self-quarantine didn't seem called for anymore.
Since I got my flu vaccine a few days before I started feeling bad, I'm wondering if it might have been some kind of reaction. Or maybe a flu bug that the vaccine either didn't address or hadn't had time to become effective against.
