That's the definition of long covid, no? How can you feel fine, get covid, then feel bad weeks later and call it "long covid"?
As per the trial design, if a patient had any symptoms of Covid and a positive Covid test, then they could be included. And despite a battery of tests, there was no physiological difference between those patients and the controls who had never been infected with Covid.
I had some symptoms of it two weeks after testing positive but now I'm living under the spectre of a lifelong disablement. Or, I'm overthinking it.
I'm slowly ramping up exercise, my only symptoms are some sleep issues as well as a relatively anxious malaise but there are a lot of life stressors unrelated to the illness I recently recovered from.
