My 3rd bout of COVID in Three years, this has been the worst. Five days and still infected, fever was brutal, but feeling better. Chest infection is almost non existent, which is not uncommon for me. But, lingering aches and pains are still there. nervous system feels better, less jarring. I Probably exasperated the illness, by assuming that I was just dehydrated (like a bad hangover), thus I exercised over the weekend, when COVID kicked in. I just didn't release it was COVID.
