A three week cold. It took several days to get bad enough to stay at home, then stay in bed. A period of intense sneezing, a head produces bags of snot, then it went to my chest. I coughed for 5 days and nights. Then, slowly, things have improved.
A month on I have the slightest residual cough which could be seasonal allergy as much as the left overs of the cold. My inclination is to keep wearing a mask as I don't want to give my cold to anyone else ... or for them to pass on further germs to me, like 'flu or Covid.
