My just turned 5 year old is self isolating till the 28th due to a positive case in her year group. She is complaining of a sore ear today, which makes sense as she has had a snotty cold for ages. No fever, no other COVID symptoms. Would you contact gp for possible ear infection? Give calpol today and see how she is tomorrow? They won't want to see her understandably without a negative COVID test, would you get her tested for that?!
I'm usually happy to go for a wait and see approach but don't want her to be in pain all over Xmas!
