I'm on day 10 of Covid and what felt like a heavy cold.
Agree with pp that the cough was tickly and not chesty.
I was bed bound for a few days with fever, sweating, snot, headaches, sneezing, chills and dizziness. It wasn't pleasant.
Eight years ago, aged 40, I had flu for the first time in my life. It completely floored me. I'd never experienced anything like it and it scared me. I hoped my bout of Covid would not be the same. Fortunately, it was not in the same league as flu (for me) and had I not done a positive LFT before symptoms, followed by a PCR when DS tested positive, then it would have appeared to be a stonking cold.
If in doubt, even if you think it's a cold, get tested.
