This is availability bias. Because you hear it in the news so much, whenever you have some weird pain in the body, the bias make you think "covid-19".

I'm not saying you don't have it, but I'm saying your mind is making it seem much more likely than it actually is.

Fact is, that when I know when something feels unusual. And when this happened, I had no idea what the Covid symptoms are like. And at the time, I also didn't think that it was this. Only after several people in my community reported the same "symptoms" did I become suspicious.

And hence, the availability bias.

Mostly sure!
