Started with a tickle in my throat sunday, yesterday small sore throat and small fever covid negative, today fever and head congestion and wicked itchy ears. positive covid test today. what day am i on and can i expect this to get worse?

Have been vaccinated & boostered? Sunday was day one of your covid infectious. Symptoms move along pretty quickly as the virus escapes the defense mechanisms in your throat. I think by day 3 or 4 if you don't develop pulmonary involvement by then you'll most likely escape with a mild case. Drink lots of fluids,isolate from others until you go 48 hours with absolutely no symptoms. Call MD as neede
