Interestingly my son has had a similar sounding virus this last two weeks; he had a fever for two days and rash all over his body, then a cough and runny nose. What’s worried me more has been his behaviour as he’s been extremely clingy, whiny etc, he’s had extremely long naps in the days like 3.5 hours and I’ve ended up having to wake him up for school runs etc. he’s not wanted to eat which is extremely unusual for him. He doesn’t have a non blanching rash but he has developed patches of dry skin. I’ve put it down to a nasty virus but if the behaviour continues I will be taking him to the docs. I think re the non blanching rash it’s worth getting him checked again if it doesn’t go away or if it increases in size. If dr thinks it’s eczema have you tried an emollient cream? Only suggesting this as when my son had HFM he developed patches of eczema and the pharmacist told me the virus had stripped the barrier off his skin and recommended a cream which built the barrier back up -it worked
I would do an appointment get another opinion as now a days doctors just claim everything as a “virus” now a days ❤️ we know our baby’s if they aren’t right ❤️
