I've might have had it. Before midsummer last year. I had issues breathing, it hurt like a motherfucker in the lungs. Like really bad. Like someone was stabbing you, short on breath etc. fever, feeling just really, really ill.
I waited at home for 5 days before they allowed me to go to the ER to get checked. My breathing was better, but I was coughing like an old rustbucket. They tried my breathing and it was around 95. Which is the lowest I ever had, I'm normal 98 to 100. They took my blood and saw I had something, but they had so many patients inside and I wasn't dying, that they recommended me to stay home.
Sweden at the time didn't do tests except when someone was on the sickbed. So after like a month, I manage to get a PCR. But then I were fine. After 6 months, you could do antibodies test and I had none inside me. So it's a mystery. The doctor I spoke to think I might have had it, but since nothing say that I did except the blood test that said I had a big increase in white blood cells, they don't know.
Tested positive for COVID last Wednesday. Feel 90% better now but my sense of smell is shot. Taste is 80% back though.
I hope you get a speedy recovery!
