My 3 year had a really high temp no lower than 38.5 but as high as 41 back in February. Was told it was just virual and to give her the usual paracetamol and ibuprofen. She was like this for 2 weeks then got a ear infection so was on antibiotics start to be her normal self then went down hill again after they had finished. She then started getting a hives type rash took her doctors and they said it's a allergy to some type of food which she has never had in the past and I've not changed anything. Seen the nurses twice as they wouldn't let me see a doctor this whole time until I demand to see one as the rash wasn't getting any better the even gave her a epipen aswell. She ended up having a blood test which showed up that her white blood cells were really low which she needed to have repeated and also tested for leukemia which showed her white blood cells were still low but there was no leukemia which we are thankful for. We had to repeat the same blood test for a 3rd time and her blood cells are back to normal. 2 doctors have both pretty much confirmed it was actually covid 19 that she had we won't actually know for 100% until she gets the antibody test but she has been fighting what ever it is for just Under 5 months now. She is a little superstar ..
