I tested positive on 22nd Jan, had cough and fever for a week and then fine. Was completely well for about a week but now have low grade fevers (37.8-38.3) most days- but otherwise completely well.
Completely normal set of bloods.
GP saying could be a 'post covid fever' 
(Will give it a few weeks and then go back and discuss further investigations- I'm not one to sit on my laurels!)
