I would like to add, i have something now that is eerily similar to something i had back late dec 2019 - jan 2020, a weird malaise and a cough that lasted weeks thats caused by deep feeling phelm within the lungs with no other symptoms, it wasnt to rough, but because it lasted so long it wore me down.
then everybody around me over the next 2 years got covid, i never caught it, despite mixing with tons of people who tested positive the next day after sitting close to me etc, for a while i thought i was some kind of immune carrier. eventually i got delta last holidays, and it was mild on the lungs, with some painful aches but generally like a moderate flu, but the fever was the worst ive ever experience, just shy of 105f at peak, it was nuts, i was about 30 mins away from calling an ambulance at that point, it felt like the most fake unnatural sickness i have ever experienced, took me like 2 weeks to recover 95% and another 2 weeks to feel back to normal.
then again in august, i started getting these weird aches in my legs, the exact same pains i felt when i got delta and a weird cold coming on, and i felt a bit run down, so i thought huh, ill do a rapid test, covid again, right when omicron was doing the rounds, kicked it than time in 5 days, was fairly mild, didnt hit the lungs again either, fever was nowhere near as bad.
Im sick again right now, its showing negative on lateral tests, feels like exactly what i caught in dec19/jan20...personally i think this is my 4th time ive had covid, i think its just not showing on tests now, could be the viral epitopes have mutated enough that it doesnt show on tests because the protein doesnt bind, or its been modified deliberately to not show on testing
