Andrea Piacquadio/PexelsYou wake with a sore throat and realise you are sick. Is this going to be a two-day or a two-week illness? Should you go to a doctor or just go to bed?
Most respiratory illnesses have very similar symptoms at the start: sore throat, congested or runny nose, headache, fatigue and fever. This may progress to a dry cough.
