I'm on day 2, having had a high temperature on day 0 (the day I tested positive) and today. Apart from a cough and sore throat I can feel my nose on fire! 
I can still smell strong smells like Vicks but am put off my food and can feel this burning tight sensation in my nose. Anyone else? I thought Omicron was mild. I had 2 vaccines and the booster. Is this Delta, possibly or is it impossible to say?
