Has anyone else had a flu type virus? Started 11 days ago with horrendously sore throat, was not able to get out of bed for a few days - headache, chills, achy joints, tiredness, slight cough, achy back. Got a sick note for work this week but still struggling with tiredness, headache (especially come afternoon/evening) and wondering if I should stay off next week or part of next week but don't want to feel like I am taking the mick. Done LFTs which are all coming back negative for covid.
