Both of my children (age 5 and 8) have rashes behind their ears. The rash is a combo of red, slightly swollen skin and bumps - looks very irritated. They both also have head colds - mild nasal congestion, sneezing, etc. They don t otherwise appear sick - good energy, etc. Can this rash be associated with the head cold? The climate here is cool and dry right now so a heat/humidity rash doesn t make sense and neither have a history of rashes, eczema.
