I've had many family members refer to having long covid because they had a persistent stuffy nose for a few months. Prob virus related to some degree but the looseness of the language makes invites skepticism.
Also some people also love being very vocal about any possible pathology they might have as a political position. Just invites more skepticism.
But, what I'm trying to say in my layman way is, I feel like I get sick differently after having covid. It's more frequent and lasts way longer. I'm currently at the tail end of a ~4 week long "cold" during which it felt like I'd improve/regress each week and it varied from my being completely functional to having fairly bedridden days. It was all just a "common cold", I think; who knows I might have had covid again (I'm not getting tested each time I get sick any more). These "colds" have been happening roughly every 3-6 months the last couple years since I got covid. Prior to that, I'd get sick only about once a year and sometimes 2-3 times without getting sick. Duration of sickness previously was typically 3-5 days, very rarely ever >1 week. Not sure if it's related, but the time of year is off too. I almost never got sick in the summer months before. Where I live it's been above 100F most of the past several weeks and typically I get sick in shoulder season months (Nov-Dec / Feb-Mar for my locale).
