Chicken soup, because it’s a cold.
A cold or the flu. Certainly not “Covid” unless, possibly, you got the jab.
There were several confirmed cases at the church my grandchildren attend. My 13 year old granddaughter had stomach problems and the sniffles. Those are the symptoms we’ve been told those confirmed cases had. She is feeling much better after three days. No doctor needed.
Yup.
Deal with it like any other cold.
