I've been feeling rubbish for a few days now with breathlessness, weird back of head headache, extreme tiredness, loss of appetite, bit of an achy chest and a really achy back and neck. Not been at all Ill before this. Also no asthma or anaemia, as I have been tested. Just wondered if this could be an atypical covid presentation? I've been referred for a chest xray , but hopefully that is just a precaution by the docs.
