my son is 4 years old, about 39lbs and has had a temp of 101-103 for over 24 hours now. he is complaining of his head hurting a lot, and won t really eat or drink because he says it hurts to. he was just given a bath and once he got out i realized he started to get a blotchy red/pink rash on both arms, his cheeks, chin , and neck . don t know what to do or what this could be
