my 5 year old had a slight fever at 101 on Wed. We picked him up from school. Then he started to have a rash around his mouth on that night, slight pink/almost not visible to naked eye tiny bumps. The next morning it spread around his face, then throughout his entire body except his hand, feet and ears. I have did some research and it may seems like a rash from his fever? heat rash? But his fever since has gone away, he has only slight runny nose now but his rash has only slightly improved. We have given him a dose of childrens claritin each day for 3 days now. Anyone know what this may be? I am going to bring him in to see a doctor if it doesn't improve in another 2/3 days but wondering if I should bring him to ER instead if it's something serious. Thx!
