It’s different for everyone. A friend in her 80s said she wouldn’t have known she had it if she hadn’t lost her sense of smell for 24 hours. DH and I tested positive 3 and a half weeks ago. He’s asthmatic, but just had mild cold symptoms for two days, then straight back to normal. I had a few very mild symptoms off and on over the 10 days - bit of a cough, fuzzy headed, dozed a lot. I only had to take paracetamol once. I did lose my sense of smell on day 5, but it’s coming back gradually. I haven’t got my full energy back yet, but it can take a while.
Hope you feel better soon, Parky.
