I've been unwell since Tuesday. Sore throat, head and body aches and so tired. Work has been tough so that hasn't helped. Virtually lost my voice. No cold-sneezing or snotty nose etc. I'm still feeling rubbish and coughed up blood tonight-not a lot but never done it before. My chest is sore too. I thought it was just viral nut should I stay off on Monday and see Dr? Or nothing to worry about and wait it out?
