DS aged 6 tested positive 2 weeks ago and was totally fine throughout. A very slight cough and snotty nose day 0 and day 1 but otherwise his usual energetic self. Went back to school mid week and on Thurs night and last night has complained of feeling 'tired like I can't move'. Today he doesn't want to go to football, which he loves usually, because he's tired. Anyone else's dc been like this after covid even though they were never actually poorly?
