Day 3/4 here (positive LFT and cough on Boxing Day evening). So far my symptoms have been: day 1 and 2 very dry cough and tickly throat. Day 3: blocked sinuses, headache. Day 4 (today): runny nose, sneezing.
Thankfully I haven’t had any body aches, vomiting or extreme fatigue - I’m tired but DC are not sleeping at the moment so don’t think that’s a Covid symptom!
So far fairly mild for me thankfully. I had my booster 4 days before testing positive so may have had some extra immunity I guess.
